# Jaeger
|
||||
|
||||
[Jaeger](https://www.jaegertracing.io/) is a distributed tracing system.
|
||||
|
||||
## Introduction
|
||||
|
||||
This chart adds all components required to run Jaeger as described in the [jaeger-kubernetes](https://github.com/jaegertracing/jaeger-kubernetes) GitHub page for a production-like deployment. The chart default will deploy a new Cassandra cluster (using the [cassandra chart](https://github.com/kubernetes/charts/tree/master/incubator/cassandra)), but also supports using an existing Cassandra cluster, deploying a new ElasticSearch cluster (using the [elasticsearch chart](https://github.com/elastic/helm-charts/tree/master/elasticsearch)), or connecting to an existing ElasticSearch cluster. Once the storage backend is available, the chart will deploy jaeger-agent as a DaemonSet and deploy the jaeger-collector and jaeger-query components as Deployments.
|
||||
|
||||
## Installing the Chart
|
||||
|
||||
Add the Jaeger Tracing Helm repository:
|
||||
|
||||
```bash
|
||||
helm repo add jaegertracing https://jaegertracing.github.io/helm-charts
|
||||
```
|
||||
|
||||
To install the chart with the release name `jaeger`, run the following command:
|
||||
|
||||
```bash
|
||||
helm install jaeger jaegertracing/jaeger
|
||||
```
|
||||
|
||||
By default, the chart deploys the following:
|
||||
|
||||
- Jaeger Agent DaemonSet
|
||||
- Jaeger Collector Deployment
|
||||
- Jaeger Query (UI) Deployment
|
||||
- Cassandra StatefulSet
|
||||
|
||||
|
||||
|
||||
IMPORTANT NOTE: For testing purposes, the footprint for Cassandra can be reduced significantly in the event resources become constrained (such as running on your local laptop or in a Vagrant environment). You can override the resources required run running this command:
|
||||
|
||||
```bash
|
||||
helm install jaeger jaegertracing/jaeger \
|
||||
--set cassandra.config.max_heap_size=1024M \
|
||||
--set cassandra.config.heap_new_size=256M \
|
||||
--set cassandra.resources.requests.memory=2048Mi \
|
||||
--set cassandra.resources.requests.cpu=0.4 \
|
||||
--set cassandra.resources.limits.memory=2048Mi \
|
||||
--set cassandra.resources.limits.cpu=0.4
|
||||
```
|
||||
|
||||
## Installing the Chart using an Existing Cassandra Cluster
|
||||
|
||||
If you already have an existing running Cassandra cluster, you can configure the chart as follows to use it as your backing store (make sure you replace `<HOST>`, `<PORT>`, etc with your values):
|
||||
|
||||
```bash
|
||||
helm install jaeger jaegertracing/jaeger \
|
||||
--set provisionDataStore.cassandra=false \
|
||||
--set storage.cassandra.host=<HOST> \
|
||||
--set storage.cassandra.port=<PORT> \
|
||||
--set storage.cassandra.user=<USER> \
|
||||
--set storage.cassandra.password=<PASSWORD>
|
||||
```
|
||||
|
||||
## Installing the Chart using an Existing Cassandra Cluster with TLS
|
||||
|
||||
If you already have an existing running Cassandra cluster with TLS, you can configure the chart as follows to use it as your backing store:
|
||||
|
||||
Content of the `values.yaml` file:
|
||||
|
||||
```YAML
|
||||
storage:
|
||||
type: cassandra
|
||||
cassandra:
|
||||
host: <HOST>
|
||||
port: <PORT>
|
||||
user: <USER>
|
||||
password: <PASSWORD>
|
||||
tls:
|
||||
enabled: true
|
||||
secretName: cassandra-tls-secret
|
||||
|
||||
provisionDataStore:
|
||||
cassandra: false
|
||||
```
|
||||
|
||||
Content of the `jaeger-tls-cassandra-secret.yaml` file:
|
||||
|
||||
```YAML
|
||||
apiVersion: v1
|
||||
kind: Secret
|
||||
metadata:
|
||||
name: cassandra-tls-secret
|
||||
data:
|
||||
commonName: <SERVER NAME>
|
||||
ca-cert.pem: |
|
||||

|
||||
<CERT>
|
||||
-----END CERTIFICATE-----
|
||||
client-cert.pem: |
|
||||
-----BEGIN CERTIFICATE-----
|
||||
<CERT>
|
||||
-----END CERTIFICATE-----
|
||||
client-key.pem: |
|
||||
-----BEGIN RSA PRIVATE KEY-----
|
||||
-----END RSA PRIVATE KEY-----
|
||||
cqlshrc: |
|
||||
[ssl]
|
||||
certfile = ~/.cassandra/ca-cert.pem
|
||||
userkey = ~/.cassandra/client-key.pem
|
||||
usercert = ~/.cassandra/client-cert.pem
|
||||
|
||||
```
|
||||
|
||||
```bash
|
||||
kubectl apply -f jaeger-tls-cassandra-secret.yaml
|
||||
helm install jaeger jaegertracing/jaeger --values values.yaml
|
||||
```
|
||||
|
||||
## Installing the Chart using a New ElasticSearch Cluster
|
||||
|
||||
To install the chart with the release name `jaeger` using a new ElasticSearch cluster instead of Cassandra (default), run the following command:
|
||||
|
||||
```bash
|
||||
helm install jaeger jaegertracing/jaeger \
|
||||
--set provisionDataStore.cassandra=false \
|
||||
--set provisionDataStore.elasticsearch=true \
|
||||
--set storage.type=elasticsearch
|
||||
```
|
||||
|
||||
## Installing the Chart using an Existing Elasticsearch Cluster
|
||||
|
||||
A release can be configured as follows to use an existing ElasticSearch cluster as it as the storage backend:
|
||||
|
||||
```bash
|
||||
helm install jaeger jaegertracing/jaeger \
|
||||
--set provisionDataStore.cassandra=false \
|
||||
--set storage.type=elasticsearch \
|
||||
--set storage.elasticsearch.host=<HOST> \
|
||||
--set storage.elasticsearch.port=<PORT> \
|
||||
--set storage.elasticsearch.user=<USER> \
|
||||
--set storage.elasticsearch.password=<password>
|
||||
```
|
||||
|
||||
## Installing the Chart using an Existing ElasticSearch Cluster with TLS
|
||||
|
||||
If you already have an existing running ElasticSearch cluster with TLS, you can configure the chart as follows to use it as your backing store:
|
||||
|
||||
Content of the `jaeger-values.yaml` file:
|
||||
|
||||
```YAML
|
||||
storage:
|
||||
type: elasticsearch
|
||||
elasticsearch:
|
||||
host: <HOST>
|
||||
port: <PORT>
|
||||
scheme: https
|
||||
user: <USER>
|
||||
password: <PASSWORD>
|
||||
provisionDataStore:
|
||||
cassandra: false
|
||||
elasticsearch: false
|
||||
query:
|
||||
cmdlineParams:
|
||||
es.tls.ca: "/tls/es.pem"
|
||||
extraConfigmapMounts:
|
||||
- name: jaeger-tls
|
||||
mountPath: /tls
|
||||
subPath: ""
|
||||
configMap: jaeger-tls
|
||||
readOnly: true
|
||||
collector:
|
||||
cmdlineParams:
|
||||
es.tls.ca: "/tls/es.pem"
|
||||
extraConfigmapMounts:
|
||||
- name: jaeger-tls
|
||||
mountPath: /tls
|
||||
subPath: ""
|
||||
configMap: jaeger-tls
|
||||
readOnly: true
|
||||
spark:
|
||||
enabled: true
|
||||
cmdlineParams:
|
||||
java.opts: "-Djavax.net.ssl.trustStore=/tls/trust.store -Djavax.net.ssl.trustStorePassword=changeit"
|
||||
extraConfigmapMounts:
|
||||
- name: jaeger-tls
|
||||
mountPath: /tls
|
||||
subPath: ""
|
||||
configMap: jaeger-tls
|
||||
readOnly: true
|
||||
|
||||
```
|
||||
|
||||
Generate configmap jaeger-tls:
|
||||
|
||||
```bash
|
||||
keytool -import -trustcacerts -keystore trust.store -storepass changeit -alias es-root -file es.pem
|
||||
kubectl create configmap jaeger-tls --from-file=trust.store --from-file=es.pem
|
||||
```
|
||||
|
||||
```bash
|
||||
helm install jaeger jaegertracing/jaeger --values jaeger-values.yaml
|
||||
```
|
||||
|
||||
## Installing the Chart with Ingester enabled
|
||||
|
||||
The architecture illustrated below can be achieved by enabling the ingester component. When enabled, Cassandra or Elasticsearch (depending on the configured values) now becomes the ingester's storage backend, whereas Kafka becomes the storage backend of the collector service.
|
||||
|
||||
|
||||
|
||||
## Installing the Chart with Ingester enabled using a New Kafka Cluster
|
||||
|
||||
To provision a new Kafka cluster along with jaeger-ingester:
|
||||
|
||||
```bash
|
||||
helm install jaeger jaegertracing/jaeger \
|
||||
--set provisionDataStore.kafka=true \
|
||||
--set ingester.enabled=true
|
||||
```
|
||||
|
||||
## Installing the Chart with Ingester using an existing Kafka Cluster
|
||||
|
||||
You can use an exisiting Kafka cluster with jaeger too
|
||||
|
||||
```bash
|
||||
helm install jaeger jaegertracing/jaeger \
|
||||
--set ingester.enabled=true \
|
||||
--set storage.kafka.brokers={<BROKER1:PORT>,<BROKER2:PORT>} \
|
||||
--set storage.kafka.topic=<TOPIC>
|
||||
```
|
||||
|
||||

# Cassandra
|
||||
A Cassandra Chart for Kubernetes
|
||||
|
||||
## Install Chart
|
||||
To install the Cassandra Chart into your Kubernetes cluster (This Chart requires persistent volume by default, you may need to create a storage class before install chart. To create storage class, see [Persist data](#persist_data) section)
|
||||
|
||||
```bash
|
||||
helm install --namespace "cassandra" -n "cassandra" incubator/cassandra
|
||||
```
|
||||
|
||||
After installation succeeds, you can get a status of Chart
|
||||
|
||||
```bash
|
||||
helm status "cassandra"
|
||||
```
|
||||
|
||||
If you want to delete your Chart, use this command
|
||||
```bash
|
||||
helm delete --purge "cassandra"
|
||||
```
|
||||
|
||||
## Upgrading
|
||||
|
||||
To upgrade your Cassandra release, simply run
|
||||
|
||||
```bash
|
||||
helm upgrade "cassandra" incubator/cassandra
|
||||
```
|
||||
|
||||
### 0.12.0
|
||||
|
||||
This version fixes https://github.com/helm/charts/issues/7803 by removing mutable labels in `spec.VolumeClaimTemplate.metadata.labels` so that it is upgradable.
|
||||
|
||||
Until this version, in order to upgrade, you have to delete the Cassandra StatefulSet before upgrading:
|
||||
```bash
|
||||
$ kubectl delete statefulset --cascade=false my-cassandra-release
|
||||
```
|
||||
|
||||
|
||||
## Persist data
|
||||
You need to create `StorageClass` before able to persist data in persistent volume.
|
||||
To create a `StorageClass` on Google Cloud, run the following
|
||||
|
||||
```bash
|
||||
kubectl create -f sample/create-storage-gce.yaml
|
||||
```
|
||||
|
||||
And set the following values in `values.yaml`
|
||||
|
||||
```yaml
|
||||
persistence:
|
||||
enabled: true
|
||||
```
|
||||
|
||||
If you want to create a `StorageClass` on other platform, please see documentation here [https://kubernetes.io/docs/user-guide/persistent-volumes/](https://kubernetes.io/docs/user-guide/persistent-volumes/)
|
||||
|
||||
When running a cluster without persistence, the termination of a pod will first initiate a decommissioning of that pod.
|
||||
Depending on the amount of data stored inside the cluster this may take a while. In order to complete a graceful
|
||||
termination, pods need to get more time for it. Set the following values in `values.yaml`:
|
||||
|
||||
```yaml
|
||||
podSettings:
|
||||
terminationGracePeriodSeconds: 1800
|
||||
```
|
||||
|
||||
## Install Chart with specific cluster size
|
||||
By default, this Chart will create a cassandra with 3 nodes. If you want to change the cluster size during installation, you can use `--set config.cluster_size={value}` argument. Or edit `values.yaml`
|
||||
|
||||
For example:
|
||||
Set cluster size to 5
|
||||
|
||||
```bash
|
||||
helm install --namespace "cassandra" -n "cassandra" --set config.cluster_size=5 incubator/cassandra/
|
||||
```
|
||||
|
||||
## Install Chart with specific resource size
|
||||
By default, this Chart will create a cassandra with CPU 2 vCPU and 4Gi of memory which is suitable for development environment.
|
||||
If you want to use this Chart for production, I would recommend to update the CPU to 4 vCPU and 16Gi. Also increase size of `max_heap_size` and `heap_new_size`.
|
||||
To update the settings, edit `values.yaml`
|
||||
|
||||
## Install Chart with specific node
|
||||
Sometime you may need to deploy your cassandra to specific nodes to allocate resources. You can use node selector by edit `nodes.enabled=true` in `values.yaml`
|
||||
For example, you have 6 vms in node pools and you want to deploy cassandra to node which labeled as `cloud.google.com/gke-nodepool: pool-db`
|
||||
|
||||
Set the following values in `values.yaml`
|
||||
|
||||
```yaml
|
||||
nodes:
|
||||
enabled: true
|
||||
selector:
|
||||
nodeSelector:
|
||||
cloud.google.com/gke-nodepool: pool-db
|
||||
```
|
||||
|
||||

## Scale cassandra
|
||||
When you want to change the cluster size of your cassandra, you can use the helm upgrade command.
|
||||
|
||||
```bash
|
||||
helm upgrade --set config.cluster_size=5 cassandra incubator/cassandra
|
||||
```
|
||||
|
||||
## Get cassandra status
|
||||
You can get your cassandra cluster status by running the command
|
||||
|
||||
```bash
|
||||
kubectl exec -it --namespace cassandra $(kubectl get pods --namespace cassandra -l app=cassandra-cassandra -o jsonpath='{.items[0].metadata.name}') nodetool status
|
||||
```
|
||||
|
||||
Output
|
||||
```bash
|
||||

|
||||
|
||||
## Benchmark
|
||||
You can use [cassandra-stress](https://docs.datastax.com/en/cassandra/3.0/cassandra/tools/toolsCStress.html) tool to run the benchmark on the cluster by the following command
|
||||
|
||||
```bash
|
||||
kubectl exec -it --namespace cassandra $(kubectl get pods --namespace cassandra -l app=cassandra-cassandra -o jsonpath='{.items[0].metadata.name}') cassandra-stress
|
||||
```
|
||||
|
||||
Example of `cassandra-stress` argument
|
||||
- Run both read and write with ration 9:1
|
||||
- Operator total 1 million keys with uniform distribution
|
||||
- Use QUORUM for read/write
|
||||
- Generate 50 threads
|
||||
- Generate result in graph
|
||||
- Use NetworkTopologyStrategy with replica factor 2
|
||||
|
||||
```bash
|
||||
cassandra-stress mixed ratio\(write=1,read=9\) n=1000000 cl=QUORUM -pop dist=UNIFORM\(1..1000000\) -mode native cql3 -rate threads=50 -log file=~/mixed_autorate_r9w1_1M.log -graph file=test2.html title=test revision=test2 -schema "replication(strategy=NetworkTopologyStrategy, factor=2)"
|
||||

Cassandra CQL can be accessed via port {{ .Values.config.ports.cql }} on the following DNS name from within your cluster:
|
||||
Cassandra Thrift can be accessed via port {{ .Values.config.ports.thrift }} on the following DNS name from within your cluster:
|
||||
|
||||
If you want to connect to the remote instance with your local Cassandra CQL cli. To forward the API port to localhost:9042 run the following:
|
||||
- kubectl port-forward --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "cassandra.name" . }},release={{ .Release.Name }} -o jsonpath='{ .items[0].metadata.name }') 9042:{{ .Values.config.ports.cql }}
|
||||
|
||||
If you want to connect to the Cassandra CQL run the following:
|
||||
{{- if contains "NodePort" .Values.service.type }}
|
||||
- export CQL_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ template "cassandra.fullname" . }})
|
||||
- export CQL_HOST=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
|
||||
- cqlsh $CQL_HOST $CQL_PORT
|
||||
|
||||
{{- else if contains "LoadBalancer" .Values.service.type }}
|
||||
NOTE: It may take a few minutes for the LoadBalancer IP to be available.
|
||||
Watch the status with: 'kubectl get svc --namespace {{ .Release.Namespace }} -w {{ template "cassandra.fullname" . }}'
|
||||
- export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "cassandra.fullname" . }} -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
|
||||
- echo cqlsh $SERVICE_IP
|

|
||||
echo cqlsh 127.0.0.1 9042

You can also see the cluster status by run the following:
|
||||
- kubectl exec -it --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "cassandra.name" . }},release={{ .Release.Name }} -o jsonpath='{.items[0].metadata.name}') nodetool status
|
||||
|
||||
To tail the logs for the Cassandra pod run the following:
|
||||
- kubectl logs -f --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "cassandra.name" . }},release={{ .Release.Name }} -o jsonpath='{ .items[0].metadata.name }')
|
||||
|
||||
{{- if not .Values.persistence.enabled }}
|
||||
|
||||
Note that the cluster is running with node-local storage instead of PersistentVolumes. In order to prevent data loss,
|
||||
pods will be decommissioned upon termination. Decommissioning may take some time, so you might also want to adjust the
|
||||
pod termination gace period, which is currently set to {{ .Values.podSettings.terminationGracePeriodSeconds }} seconds.

## Requirements
|
||||
|
||||
* [Helm][] >=2.8.0 and <3.0.0
|
||||
* Kubernetes >=1.8
|
||||
* Minimum cluster requirements include the following to run this chart with
|
||||
default settings. All of these settings are configurable.
|
||||
* Three Kubernetes nodes to respect the default "hard" affinity settings
|
||||
* 1GB of RAM for the JVM heap
|
||||
|
||||
See [supported configurations][] for more details.
|
||||
|
||||
|
||||
## Installing
|
||||
|
||||
This chart is tested with 7.8.1 version.
|
||||
|
||||
* Add the Elastic Helm charts repo:
|
||||
`helm repo add elastic https://helm.elastic.co`
|
||||
|
||||
* Install 7.8.1 release:
|
||||
`helm install --name elasticsearch --version 7.8.1 elastic/elasticsearch`
|
||||
|
||||
|
||||
## Upgrading
|
||||
|
||||
Please always check [CHANGELOG.md][] and [BREAKING_CHANGES.md][] before
|
||||
upgrading to a new chart version.
|
||||
|
||||
|
||||
## Usage notes
|
||||
|
||||
* This repo includes a number of [examples][] configurations which can be used
|
||||
as a reference. They are also used in the automated testing of this chart.
|
||||
* Automated testing of this chart is currently only run against GKE (Google
|
||||
Kubernetes Engine).
|
||||
* The chart deploys a StatefulSet and by default will do an automated rolling
|
||||
update of your cluster. It does this by waiting for the cluster health to become
|
||||
green after each instance is updated. If you prefer to update manually you can
|
||||
set `OnDelete` [updateStrategy][].
|
||||
* It is important to verify that the JVM heap size in `esJavaOpts` and to set
|
||||
the CPU/Memory `resources` to something suitable for your cluster.
|
||||
* To simplify chart and maintenance each set of node groups is deployed as a
|
||||
separate Helm release. Take a look at the [multi][] example to get an idea for
|
||||
how this works. Without doing this it isn't possible to resize persistent
|
||||
volumes in a StatefulSet. By setting it up this way it makes it possible to add
|
||||
more nodes with a new storage size then drain the old ones. It also solves the
|
||||
problem of allowing the user to determine which node groups to update first when
|
||||
doing upgrades or changes.
|
||||
* We have designed this chart to be very un-opinionated about how to configure
|
||||
Elasticsearch. It exposes ways to set environment variables and mount secrets
|
||||
inside of the container. Doing this makes it much easier for this chart to
|
||||
support multiple versions with minimal changes.

## FAQ
|
||||
|
||||
### How to deploy this chart on a specific K8S distribution?
|
||||
|
||||
This chart is designed to run on production scale Kubernetes clusters with
|
||||
multiple nodes, lots of memory and persistent storage. For that reason it can be
|
||||
a bit tricky to run them against local Kubernetes environments such as
|
||||
[Minikube][].
|
||||
|
||||
This chart is highly tested with [GKE][], but some K8S distribution also
|
||||
requires specific configurations.
|
||||
|
||||
We provide examples of configuration for the following K8S providers:
|
||||
|
||||
- [Docker for Mac][]
|
||||
- [KIND][]
|
||||
- [Minikube][]
|
||||
- [MicroK8S][]
|
||||
- [OpenShift][]
|
||||
|
||||
### How to deploy dedicated nodes types?
|
||||
|
||||
All the Elasticsearch pods deployed share the same configuration. If you need to
|
||||
deploy dedicated [nodes types][] (for example dedicated master and data nodes),
|
||||
you can deploy multiple releases of this chart with different configurations
|
||||
while they share the same `clusterName` value.
|
||||
|
||||
For each Helm release, the nodes types can then be defined using `roles` value.
|
||||
|
||||
An example of Elasticsearch cluster using 2 different Helm releases for master
|
||||
and data nodes can be found in [examples/multi][].
|
||||
|
||||
#### Clustering and Node Discovery
|
||||
|
||||
This chart facilitates Elasticsearch node discovery and services by creating two
|
||||
`Service` definitions in Kubernetes, one with the name `$clusterName-$nodeGroup`
|
||||
and another named `$clusterName-$nodeGroup-headless`.
|
||||
Only `Ready` pods are a part of the `$clusterName-$nodeGroup` service, while all
|
||||
pods ( `Ready` or not) are a part of `$clusterName-$nodeGroup-headless`.
|
||||
|
||||
If your group of master nodes has the default `nodeGroup: master` then you can
|
||||
just add new groups of nodes with a different `nodeGroup` and they will
|
||||
automatically discover the correct master. If your master nodes have a different
|
||||
`nodeGroup` name then you will need to set `masterService` to
|
||||
`$clusterName-$masterNodeGroup`.
|
||||
|
||||
The chart value for `masterService` is used to populate
|
||||
`discovery.zen.ping.unicast.hosts` , which Elasticsearch nodes will use to
|
||||
contact master nodes and form a cluster.
|
||||
Therefore, to add a group of nodes to an existing cluster, setting
|
||||
`masterService` to the desired `Service` name of the related cluster is
|
||||
sufficient.
|
||||
|
||||
### How to deploy clusters with security (authentication and TLS) enabled?
|
||||
|
||||
This Helm chart can use existing [Kubernetes secrets][] to setup
|
||||
credentials or certificates for examples. These secrets should be created
|
||||
outside of this chart and accessed using [environment variables][] and volumes.
|
||||
|
||||
An example of Elasticsearch cluster using security can be found in
|
||||
[examples/security][].
|
||||
|
||||
### How to migrate from helm/charts stable chart?
|
||||
|
||||
If you currently have a cluster deployed with the [helm/charts stable][] chart
|
||||
you can follow the [migration guide][].
|
||||
|
||||
### How to install OSS version of Elasticsearch?
|
||||
|
||||
Deploying OSS version of Elasticsearch can be done by setting `image` value to
|
||||
[Elasticsearch OSS Docker image][]
|
||||
|
||||
An example of Elasticsearch cluster using OSS version can be found in
|
||||
[examples/oss][].
|
||||
|
||||
### How to install plugins?
|
||||
|
||||
The recommended way to install plugins into our Docker images is to create a
|
||||
[custom Docker image][].
|
||||
|
||||
The Dockerfile would look something like:
|
||||
|
||||
```
|
||||
ARG elasticsearch_version
|
||||
FROM docker.elastic.co/elasticsearch/elasticsearch:${elasticsearch_version}
|
||||
|
||||
RUN bin/elasticsearch-plugin install --batch repository-gcs
|
||||
```
|
||||
|
||||
And then updating the `image` in values to point to your custom image.
|
||||
|
||||
There are a couple reasons we recommend this.
|
||||
|
||||
1. Tying the availability of Elasticsearch to the download service to install
|
||||
plugins is not a great idea or something that we recommend. Especially in
|
||||
Kubernetes where it is normal and expected for a container to be moved to
|
||||
another host at random times.
|
||||
2. Mutating the state of a running Docker image (by installing plugins) goes
|
||||
against best practices of containers and immutable infrastructure.
|
||||
|
||||
### How to use the keystore?
|
||||
|
||||
#### Basic example
|
||||
|
||||
Create the secret, the key name needs to be the keystore key path. In this
|
||||
example we will create a secret from a file and from a literal string.
|
||||
|
||||
```
|
||||
kubectl create secret generic encryption_key --from-file=xpack.watcher.encryption_key=./watcher_encryption_key
|
||||
kubectl create secret generic slack_hook --from-literal=xpack.notification.slack.account.monitoring.secure_url='https://hooks.slack.com/services/asdasdasd/asdasdas/asdasd'
|
||||
```
|
||||
|
||||
To add these secrets to the keystore:
|
||||
|
||||
```
|
||||
keystore:
|
||||
- secretName: encryption_key
|
||||
- secretName: slack_hook
|
||||
```
|
||||
|
||||
#### Multiple keys
|
||||
|
||||
All keys in the secret will be added to the keystore. To create the previous
|
||||
example in one secret you could also do:
|
||||
|
||||
```
|
||||
kubectl create secret generic keystore_secrets --from-file=xpack.watcher.encryption_key=./watcher_encryption_key --from-literal=xpack.notification.slack.account.monitoring.secure_url='https://hooks.slack.com/services/asdasdasd/asdasdas/asdasd'
|
||||
```
|
||||
|
||||
```
|
||||
keystore:
|
||||
- secretName: keystore_secrets
|
||||
```
|
||||
|
||||
#### Custom paths and keys
|
||||
|
||||
If you are using these secrets for other applications (besides the Elasticsearch
|
||||
keystore) then it is also possible to specify the keystore path and which keys
|
||||
you want to add. Everything specified under each `keystore` item will be passed
|
||||
through to the `volumeMounts` section for mounting the [secret][]. In this
|
||||
example we will only add the `slack_hook` key from a secret that also has other
|
||||
keys. Our secret looks like this:
|
||||
|
||||
```
|
||||
kubectl create secret generic slack_secrets --from-literal=slack_channel='#general' --from-literal=slack_hook='https://hooks.slack.com/services/asdasdasd/asdasdas/asdasd'
|
||||
```
|
||||
|
||||
We only want to add the `slack_hook` key to the keystore at path
|
||||
`xpack.notification.slack.account.monitoring.secure_url`:
|
||||
|
||||
```
|
||||
keystore:
|
||||
- secretName: slack_secrets
|
||||
items:
|
||||
- key: slack_hook
|
||||
path: xpack.notification.slack.account.monitoring.secure_url
|
||||
```
|
||||
|
||||
You can also take a look at the [config example][] which is used as part of the
|
||||
automated testing pipeline.
|
||||
|
||||
### How to enable snapshotting?
|
||||
|
||||
1. Install your [snapshot plugin][] into a custom Docker image following the
|
||||
[how to install plugins guide][].
|
||||
2. Add any required secrets or credentials into an Elasticsearch keystore
|
||||
following the [how to use the keystore][] guide.
|
||||
3. Configure the [snapshot repository][] as you normally would.
|
||||
4. To automate snapshots you can use a tool like [curator][]. In the future
|
||||
there are plans to have Elasticsearch manage automated snapshots with
|
||||
[Snapshot Lifecycle Management][].
|
||||
|
||||
### How to configure templates post-deployment?
|
||||
|
||||
You can use `postStart` [lifecycle hooks][] to run code triggered after a
|
||||
container is created.
|
||||
|
||||
Here is an example of `postStart` hook to configure templates:
|
||||
|
||||
```yaml
|
||||
lifecycle:
|
||||
postStart:
|
||||
exec:
|
||||
command:
|
||||
- bash
|
||||
- -c
|
||||
- |
|
||||
#!/bin/bash
|
||||
# Add a template to adjust number of shards/replicas
|
||||
TEMPLATE_NAME=my_template
|
||||
INDEX_PATTERN="logstash-*"
|
||||
SHARD_COUNT=8
|
||||
REPLICA_COUNT=1
|
||||
ES_URL=http://localhost:9200
|
||||
while [[ "$(curl -s -o /dev/null -w '%{http_code}\n' $ES_URL)" != "200" ]]; do sleep 1; done
|
||||
curl -XPUT "$ES_URL/_template/$TEMPLATE_NAME" -H 'Content-Type: application/json' -d'{"index_patterns":['\""$INDEX_PATTERN"\"'],"settings":{"number_of_shards":'$SHARD_COUNT',"number_of_replicas":'$REPLICA_COUNT'}}'
|
||||
```

# Config
|
||||
|
||||
This example deploy a single node Elasticsearch 7.8.1 with authentication and
|
||||
custom [values][].
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
* Create the required secrets: `make secrets`
|
||||
|
||||
* Deploy Elasticsearch chart with the default values: `make install`
|
||||
|
||||
* You can now setup a port forward to query Elasticsearch API:
|
||||
|
||||
```
|
||||
kubectl port-forward svc/config-master 9200
|
||||
curl -u elastic:changeme http://localhost:9200/_cat/indices
|
||||
```
|
||||
|
||||
|
||||
## Testing
|
||||
|
||||
You can also run [goss integration tests][] using `make test`
|

# KIND
|
||||
|
||||
This example deploy a 3 nodes Elasticsearch 7.8.1 cluster on [Kind][]
|
||||
using [custom values][].
|
||||
|
||||
Note that this configuration should be used for test only and isn't recommended
|
||||
for production.
|
||||
|
||||
Note that Kind < 0.7.0 are affected by a [kind issue][] with mount points
|
||||
created from PVCs not writable by non-root users. [kubernetes-sigs/kind#1157][]
|
||||
fix it in Kind 0.7.0.
|
||||
|
||||
The workaround for Kind < 0.7.0 is to install manually
|
||||
[Rancher Local Path Provisioner][] and use `local-path` storage class for
|
||||
Elasticsearch volumes (see [Makefile][] instructions).
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
* For Kind >= 0.7.0: Deploy Elasticsearch chart with the default values: `make install`
|
||||
* For Kind < 0.7.0: Deploy Elasticsearch chart with `local-path` storage class: `make install-local-path`
|
||||
|
||||
* You can now setup a port forward to query Elasticsearch API:
|
||||
|
||||
```
|
||||
kubectl port-forward svc/elasticsearch-master 9200
|
||||
curl localhost:9200/_cat/indices

# MicroK8S
|
||||
|
||||
This example deploy a 3 nodes Elasticsearch 7.8.1 cluster on [MicroK8S][]
|
||||
using [custom values][].
|
||||
|
||||
Note that this configuration should be used for test only and isn't recommended
|
||||
for production.
|
||||
|
||||
|
||||
## Requirements
|
||||
|
||||
The following MicroK8S [addons][] need to be enabled:
|
||||
- `dns`
|
||||
- `helm`
|
||||
- `storage`
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
* Deploy Elasticsearch chart with the default values: `make install`
|
||||
|
||||
* You can now setup a port forward to query Elasticsearch API:
|
||||
|
||||
```
|
||||
kubectl port-forward svc/elasticsearch-master 9200
|
||||
curl localhost:9200/_cat/indices
|
||||
```

# Migration Guide from helm/charts
|
||||
|
||||
There are two viable options for migrating from the community Elasticsearch Helm
|
||||
chart from the [helm/charts][] repo.
|
||||
|
||||
1. Restoring from Snapshot to a fresh cluster
|
||||
2. Live migration by joining a new cluster to the existing cluster.
|
||||
|
||||
## Restoring from Snapshot
|
||||
|
||||
This is the recommended and preferred option. The downside is that it will
|
||||
involve a period of write downtime during the migration. If you have a way to
|
||||
temporarily stop writes to your cluster then this is the way to go. This is also
|
||||
a lot simpler as it just involves launching a fresh cluster and restoring a
|
||||
snapshot following the [restoring to a different cluster guide][].
|
||||
|
||||
## Live migration
|
||||
|
||||
If restoring from a snapshot is not possible due to the write downtime then a
|
||||
live migration is also possible. It is very important to first test this in a
|
||||
testing environment to make sure you are comfortable with the process and fully
|
||||
understand what is happening.
|
||||
|
||||
This process will involve joining a new set of master, data and client nodes to
|
||||
an existing cluster that has been deployed using the [helm/charts][] community
|
||||
chart. Nodes will then be replaced one by one in a controlled fashion to
|
||||
decommission the old cluster.
|
||||
|
||||
This example will be using the default values for the existing helm/charts
|
||||
release and for the Elastic helm-charts release. If you have changed any of the
|
||||
default values then you will need to first make sure that your values are
|
||||
configured in a compatible way before starting the migration.
|
||||
|
||||
The process will involve a re-sync and a rolling restart of all of your data
|
||||
nodes. Therefore it is important to disable shard allocation and perform a synced
|
||||
flush like you normally would during any other rolling upgrade. See the
|
||||
[rolling upgrades guide][] for more information.
|
||||
|
||||
* The default image for this chart is
|
||||
`docker.elastic.co/elasticsearch/elasticsearch` which contains the default
|
||||
distribution of Elasticsearch with a [basic license][]. Make sure to update the
|
||||
`image` and `imageTag` values to the correct Docker image and Elasticsearch
|
||||
version that you currently have deployed.
|
||||
|
||||
* Convert your current helm/charts configuration into something that is
|
||||
compatible with this chart.
|
||||
|
||||
* Take a fresh snapshot of your cluster. If something goes wrong you want to be
|
||||
able to restore your data no matter what.
|
||||
|
||||
* Check that your clusters health is green. If not abort and make sure your
|
||||
cluster is healthy before continuing:
|
||||
|
||||
```
|
||||
curl localhost:9200/_cluster/health
|
||||
```
|
||||
|
||||
* Deploy new data nodes which will join the existing cluster. Take a look at the
|
||||
configuration in [data.yml][]:
|
||||
|
||||
```
|
||||
make data
|
||||
```
|
||||
|
||||
* Check that the new nodes have joined the cluster (run this and any other curl
|
||||
commands from within one of your pods):
|
||||
|
||||
```
|
||||
curl localhost:9200/_cat/nodes
|
||||
```
|
||||
|
||||
* Check that your cluster is still green. If so we can now start to scale down
|
||||
the existing data nodes. Assuming you have the default amount of data nodes (2)
|
||||
we now want to scale it down to 1:
|
||||
|
||||
```
|
||||
kubectl scale statefulsets my-release-elasticsearch-data --replicas=1
|
||||
```
|
||||
|
||||
* Wait for your cluster to become green again:
|
||||
|
||||
```
|
||||
watch 'curl -s localhost:9200/_cluster/health'
|
||||
```
|
||||
|
||||
* Once the cluster is green we can scale down again:
|
||||
|
||||
```
|
||||
kubectl scale statefulsets my-release-elasticsearch-data --replicas=0
|
||||
```
|
||||
|
||||
* Wait for the cluster to be green again.
|
||||
* OK. We now have all data nodes running in the new cluster. Time to replace the
|
||||
masters by firstly scaling down the masters from 3 to 2. Between each step make
|
||||
sure to wait for the cluster to become green again, and check with
|
||||
`curl localhost:9200/_cat/nodes` that you see the correct amount of master
|
||||
nodes. During this process we will always make sure to keep at least 2 master
|
||||
nodes as to not lose quorum:
|
||||
|
||||
```
|
||||
kubectl scale statefulsets my-release-elasticsearch-master --replicas=2
|
||||
```
|
||||
|
||||
* Now deploy a single new master so that we have 3 masters again. See
|
||||
[master.yml][] for the configuration:
|
||||
|
||||
```
|
||||
make master
|
||||
```
|
||||
|
||||
* Scale down old masters to 1:
|
||||
|
||||
```
|
||||
kubectl scale statefulsets my-release-elasticsearch-master --replicas=1
|
||||
```
|
||||
|
||||
* Edit the masters in [masters.yml][] to 2 and redeploy:
|
||||
|
||||
```
|
||||
make master
|
||||
```
|
||||
|
||||
* Scale down the old masters to 0:
|
||||
|
||||
```
|
||||
kubectl scale statefulsets my-release-elasticsearch-master --replicas=0
|
||||
```
|
||||
|
||||
* Edit the [masters.yml][] to have 3 replicas and remove the
|
||||
`discovery.zen.ping.unicast.hosts` entry from `extraEnvs` then redeploy the
|
||||
masters. This will make sure all 3 masters are running in the new cluster and
|
||||
are pointing at each other for discovery:
|
||||
|
||||
```
|
||||
make master
|
||||
```
|
||||
|
||||
* Remove the `discovery.zen.ping.unicast.hosts` entry from `extraEnvs` then
|
||||
redeploy the data nodes to make sure they are pointing at the new masters:
|
||||
|
||||
```
|
||||
make data
|
||||
```
|
||||
|
||||
* Deploy the client nodes:
|
||||
|
||||
```
|
||||
make client
|
||||
```
|
||||
|
||||
* Update any processes that are talking to the existing client nodes and point
|
||||
them to the new client nodes. Once this is done you can scale down the old
|
||||
client nodes:
|
||||
|
||||
```
|
||||
kubectl scale deployment my-release-elasticsearch-client --replicas=0
|
||||
```
|
||||
|
||||
* The migration should now be complete. After verifying that everything is
|
||||
working correctly you can cleanup leftover resources from your old cluster.

# Minikube
|
||||
|
||||
This example deploy a 3 nodes Elasticsearch 7.8.1 cluster on [Minikube][]
|
||||
using [custom values][].
|
||||
|
||||
If helm or kubectl timeouts occur, you may consider creating a minikube VM with
|
||||
more CPU cores or memory allocated.
|
||||
|
||||
Note that this configuration should be used for test only and isn't recommended
|
||||
for production.
|
||||
|
||||
|
||||
## Requirements
|
||||
|
||||
In order to properly support the required persistent volume claims for the
|
||||
Elasticsearch StatefulSet, the `default-storageclass` and `storage-provisioner`
|
||||
minikube addons must be enabled.
|
||||
|
||||
```
|
||||
minikube addons enable default-storageclass
|
||||
minikube addons enable storage-provisioner
|
||||
```
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
* Deploy Elasticsearch chart with the default values: `make install`
|
||||
|
||||
* You can now setup a port forward to query Elasticsearch API:
|
||||
|
||||

|
||||
- `helm-es-multi-data` for the 3 data nodes using [data values][]
|
||||
|
||||
## Usage
|
||||
|
||||
* Deploy the 2 Elasticsearch releases: `make install`
|
||||
|
||||
* You can now setup a port forward to query Elasticsearch API:
|
||||

# OSS
|
||||
|
||||
This example deploy a 3 nodes Elasticsearch 7.8.1 cluster using
|
||||
[Elasticsearch OSS][] version.
|
||||
|
||||
## Usage
|
||||
|
||||
* Deploy Elasticsearch chart with the default values: `make install`
|
||||
|
||||
* You can now setup a port forward to query Elasticsearch API:
|
||||
|
||||
```
|
||||
kubectl port-forward svc/oss-master 9200
|
||||
curl localhost:9200/_cat/indices
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
You can also run [goss integration tests][] using `make test`

# Security
|
||||
|
||||
This example deploy a 3 nodes Elasticsearch 7.8.1 with authentication and
|
||||
autogenerated certificates for TLS (see [values][]).
|
||||
|
||||
Note that this configuration should be used for test only. For a production
|
||||
deployment you should generate SSL certificates following the [official docs][].
|
||||
|
||||
## Usage
|
||||
|
||||
* Create the required secrets: `make secrets`
|
||||
|
||||
* Deploy Elasticsearch chart with the default values: `make install`
|
||||
|
||||
* You can now setup a port forward to query Elasticsearch API:
|
||||
|
||||
```
|
||||
kubectl port-forward svc/security-master 9200
|
||||
curl -u elastic:changeme https://localhost:9200/_cat/indices
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
You can also run [goss integration tests][] using `make test`

# Upgrade
|
||||
|
||||
This example will deploy a 3 node Elasticsearch cluster using an old chart version,
|
||||
then upgrade it to version 7.8.1.
|
||||
|
||||
The following upgrades are tested:
|
||||
- Upgrade from [7.0.0-alpha1][] version on K8S <1.16
|
||||
- Upgrade from [7.4.0][] version on K8S >=1.16 (Elasticsearch chart < 7.4.0 are
|
||||
not compatible with K8S >= 1.16)
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
Running `make install` command will do first install and 7.8.1 upgrade.
|
||||
|
||||
Note: [jq][] is a requirement for this make target.
|
||||
|
||||
|
||||
## Testing
|
||||
|
||||
You can also run [goss integration tests][] using `make test`.

||||

# Apache Kafka Helm Chart
|
||||
|
||||
This is an implementation of Kafka StatefulSet found here:
|
||||
|
||||
* https://github.com/Yolean/kubernetes-kafka
|
||||
|
||||
## Pre Requisites:
|
||||
|
||||
* Kubernetes 1.3 with alpha APIs enabled and support for storage classes
|
||||
|
||||
* PV support on underlying infrastructure
|
||||
|
||||
* Requires at least `v2.0.0-beta.1` version of helm to support
|
||||
dependency management with requirements.yaml
|
||||
|
||||
## StatefulSet Details
|
||||
|
||||
* https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/
|
||||
|
||||
## StatefulSet Caveats
|
||||
|
||||
* https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#limitations
|
||||
|
||||
## Chart Details
|
||||
|
||||
This chart will do the following:
|
||||
|
||||
* Implement a dynamically scalable kafka cluster using Kubernetes StatefulSets
|
||||
|
||||
* Implement a dynamically scalable zookeeper cluster as another Kubernetes StatefulSet required for the Kafka cluster above
|
||||
|
||||
* Expose Kafka protocol endpoints via NodePort services (optional)
|
||||
|
||||
### Installing the Chart
|
||||
|
||||
To install the chart with the release name `my-kafka` in the default
|
||||
namespace:
|
||||
|
||||
```
|
||||
$ helm repo add incubator http://storage.googleapis.com/kubernetes-charts-incubator
|
||||
$ helm install --name my-kafka incubator/kafka
|
||||
```
|
||||
|
||||
If using a dedicated namespace(recommended) then make sure the namespace
|
||||
exists with:
|
||||
|
||||
```
|
||||
$ helm repo add incubator http://storage.googleapis.com/kubernetes-charts-incubator
|
||||
$ kubectl create ns kafka
|
||||
$ helm install --name my-kafka --namespace kafka incubator/kafka
|
||||
```
|
||||
|
||||
This chart includes a ZooKeeper chart as a dependency to the Kafka
|
||||
cluster in its `requirement.yaml` by default. The chart can be customized using the
|
||||

||||
```
|
||||
|
||||
### Connecting to Kafka from inside Kubernetes
|
||||
|
||||
You can connect to Kafka by running a simple pod in the K8s cluster like this with a configuration like this:
|
||||
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: Pod
|
||||
metadata:
|
||||
name: testclient
|
||||
namespace: kafka
|
||||
spec:
|
||||
containers:
|
||||
- name: kafka
|
||||
image: solsson/kafka:0.11.0.0
|
||||
command:
|
||||
- sh
|
||||
- -c
|
||||
- "exec tail -f /dev/null"
|
||||
```
|
||||
|
||||
Once you have the testclient pod above running, you can list all kafka
|
||||
topics with:
|
||||
|
||||
` kubectl -n kafka exec -ti testclient -- ./bin/kafka-topics.sh --zookeeper
|
||||
my-release-zookeeper:2181 --list`
|
||||
|
||||
Where `my-release` is the name of your helm release.
|
||||
|
||||
## Extensions
|
||||
|
||||
Kafka has a rich ecosystem, with lots of tools. This sections is intended to compile all of those tools for which a corresponding Helm chart has already been created.
|
||||
|
||||
- [Schema-registry](https://github.com/kubernetes/charts/tree/master/incubator/schema-registry) - A confluent project that provides a serving layer for your metadata. It provides a RESTful interface for storing and retrieving Avro schemas.
|
||||
|
||||
## Connecting to Kafka from outside Kubernetes
|
||||
|
||||
### NodePort External Service Type
|
||||
|
||||
Review and optionally override to enable the example text concerned with external access in `values.yaml`.
|
||||
|
||||
Once configured, you should be able to reach Kafka via NodePorts, one per replica. In kops where private,
|
||||
topology is enabled, this feature publishes an internal round-robin DNS record using the following naming
|
||||
scheme. The external access feature of this chart was tested with kops on AWS using flannel networking.
|
||||
If you wish to enable external access to Kafka running in kops, your security groups will likely need to
|
||||
be adjusted to allow non-Kubernetes nodes (e.g. bastion) to access the Kafka external listener port range.
|
||||
|
||||
```
|
||||
{{ .Release.Name }}.{{ .Values.external.domain }}
|
||||
```
|
||||
|
||||
If `external.distinct` is set theses entries will be prefixed with the replica number or broker id.
|
||||
|
||||
```
|
||||
{{ .Release.Name }}-<BROKER_ID>.{{ .Values.external.domain }}
|
||||
```
|
||||
|
||||
Port numbers for external access used at container and NodePort are unique to each container in the StatefulSet.
|
||||
Using the default `external.firstListenerPort` number with a `replicas` value of `3`, the following
|
||||
container and NodePorts will be opened for external access: `31090`, `31091`, `31092`. All of these ports should
|
||||
be reachable from any host to NodePorts are exposed because Kubernetes routes each NodePort from entry node
|
||||
to pod/container listening on the same port (e.g. `31091`).
|
||||
|
||||
The `external.servicePort` at each external access service (one such service per pod) is a relay toward
|
||||
the a `containerPort` with a number matching its respective `NodePort`. The range of NodePorts is set, but
|
||||
should not actually listen, on all Kafka pods in the StatefulSet. As any given pod will listen only one
|
||||
such port at a time, setting the range at every Kafka pod is a reasonably safe configuration.
|
||||

### LoadBalancer External Service Type
|
||||
|
||||
The load balancer external service type differs from the node port type by routing to the `external.servicePort` specified in the service for each statefulset container (if `external.distinct` is set). If `external.distinct` is false, `external.servicePort` is unused and will be set to the sum of `external.firstListenerPort` and the replica number. It is important to note that `external.firstListenerPort` does not have to be within the configured node port range for the cluster, however a node port will be allocated.

## Known Limitations
|
||||
|
||||
* Only supports storage options that have backends for persistent volume claims (tested mostly on AWS)
|
||||
* KAFKA_PORT will be created as an envvar and brokers will fail to start when there is a service named `kafka` in the same namespace. We work around this be unsetting that envvar `unset KAFKA_PORT`.

|
||||
## Prometheus Stats
|
||||
|
||||
### Prometheus vs Prometheus Operator
|
||||
|
||||
Standard Prometheus is the default monitoring option for this chart. This chart also supports the CoreOS Prometheus Operator,
|
||||
which can provide additional functionality like automatically updating Prometheus and Alert Manager configuration. If you are
|
||||
interested in installing the Prometheus Operator please see the [CoreOS repository](https://github.com/coreos/prometheus-operator/tree/master/helm) for more information or
|
||||
read through the [CoreOS blog post introducing the Prometheus Operator](https://coreos.com/blog/the-prometheus-operator.html)
|
||||
|
||||
### JMX Exporter
|
||||
|
||||
The majority of Kafka statistics are provided via JMX and are exposed via the [Prometheus JMX Exporter](https://github.com/prometheus/jmx_exporter).
|
||||
|
||||
The JMX Exporter is a general purpose prometheus provider which is intended for use with any Java application. Because of this, it produces a number of statistics which
|
||||
may not be of interest. To help in reducing these statistics to their relevant components we have created a curated whitelist `whitelistObjectNames` for the JMX exporter.
|
||||
This whitelist may be modified or removed via the values configuration.
|
||||
|
||||
To accommodate compatibility with the Prometheus metrics, this chart performs transformations of raw JMX metrics. For example, broker names and topics names are incorporated
|
||||
into the metric name instead of becoming a label. If you are curious to learn more about any default transformations to the chart metrics, please have reference the [configmap template](https://github.com/kubernetes/charts/blob/master/incubator/kafka/templates/jmx-configmap.yaml).
|
||||
|
||||
### Kafka Exporter
|
||||
|
||||
The [Kafka Exporter](https://github.com/danielqsj/kafka_exporter) is a complementary metrics exporter to the JMX Exporter. The Kafka Exporter provides additional statistics on Kafka Consumer Groups.

# incubator/zookeeper
|
||||
|
||||
This helm chart provides an implementation of the ZooKeeper [StatefulSet](http://kubernetes.io/docs/concepts/abstractions/controllers/statefulsets/) found in Kubernetes Contrib [Zookeeper StatefulSet](https://github.com/kubernetes/contrib/tree/master/statefulsets/zookeeper).
|
||||
|
||||
## Prerequisites
|
||||
* Kubernetes 1.10+
|
||||
* PersistentVolume support on the underlying infrastructure
|
||||
* A dynamic provisioner for the PersistentVolumes
|
||||
* A familiarity with [Apache ZooKeeper 3.5.x](https://zookeeper.apache.org/doc/r3.5.5/)
|
||||
|
||||
## Chart Components
|
||||
This chart will do the following:
|
||||
|
||||
* Create a fixed size ZooKeeper ensemble using a [StatefulSet](http://kubernetes.io/docs/concepts/abstractions/controllers/statefulsets/).
|
||||
* Create a [PodDisruptionBudget](https://kubernetes.io/docs/tasks/configure-pod-container/configure-pod-disruption-budget/) so kubectl drain will respect the Quorum size of the ensemble.
|
||||
* Create a [Headless Service](https://kubernetes.io/docs/concepts/services-networking/service/) to control the domain of the ZooKeeper ensemble.
|
||||
* Create a Service configured to connect to the available ZooKeeper instance on the configured client port.
|
||||
* Optionally apply a [Pod Anti-Affinity](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#inter-pod-affinity-and-anti-affinity-beta-feature) to spread the ZooKeeper ensemble across nodes.
|
||||
* Optionally start JMX Exporter and Zookeeper Exporter containers inside Zookeeper pods.
|
||||
* Optionally create a job which creates Zookeeper chroots (e.g. `/kafka1`).
|
||||
* Optionally create a Prometheus ServiceMonitor for each enabled exporter container
|
||||
|
||||
## Installing the Chart
|
||||
You can install the chart with the release name `zookeeper` as below.
|
||||
|
||||
```console
|
||||
$ helm repo add incubator http://storage.googleapis.com/kubernetes-charts-incubator
|
||||
$ helm install --name zookeeper incubator/zookeeper
|
||||
```
|
||||
|
||||
If you do not specify a name, helm will select a name for you.
|
||||
|
||||
### Installed Components
|
||||
You can use `kubectl get` to view all of the installed components.
|
||||
|
||||
```console{%raw}

1. `statefulsets/zookeeper` is the StatefulSet created by the chart.
|
||||
1. `po/zookeeper-<0|1|2>` are the Pods created by the StatefulSet. Each Pod has a single container running a ZooKeeper server.
|
||||
1. `svc/zookeeper-headless` is the Headless Service used to control the network domain of the ZooKeeper ensemble.
|
||||
1. `svc/zookeeper` is a Service that can be used by clients to connect to an available ZooKeeper server.
|
||||
1. `servicemonitor/zookeeper` is a Prometheus ServiceMonitor which scrapes the jmx-exporter metrics endpoint
|
||||
1. `servicemonitor/zookeeper-exporter` is a Prometheus ServiceMonitor which scrapes the zookeeper-exporter metrics endpoint
|
||||
|
||||
## Configuration
|
||||
You can specify each parameter using the `--set key=value[,key=value]` argument to `helm install`.
|
||||
|
||||
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
|
||||
|
||||
```console
|
||||
$ helm install --name my-release -f values.yaml incubator/zookeeper
|
||||
```
|
||||
|
||||
## Default Values
|
||||
|
||||
- You can find all user-configurable settings, their defaults and commentary about them in [values.yaml](values.yaml).
|
||||
|
||||
## Deep Dive
|
||||
|
||||
## Image Details
|
||||
The image used for this chart is based on Alpine 3.9.0.
|
||||
|
||||
## JVM Details
|
||||
The Java Virtual Machine used for this chart is the OpenJDK JVM 8u192 JRE (headless).
|
||||
|
||||
## ZooKeeper Details
|
||||
The chart defaults to ZooKeeper 3.5 (latest released version).
|
||||
|
||||
## Failover
|
||||
You can test failover by killing the leader. Insert a key:
|
||||
```console
|
||||
$ kubectl exec zookeeper-0 -- bin/zkCli.sh create /foo bar;
|
||||
$ kubectl exec zookeeper-2 -- bin/zkCli.sh get /foo;
|
||||
```
|
||||
|
||||
Watch existing members:
|
||||
```console
|
||||
$ kubectl run --attach bbox --image=busybox --restart=Never -- sh -c 'while true; do for i in 0 1 2; do echo zk-${i} $(echo stats | nc <pod-name>-${i}.<headless-service-name>:2181 | grep Mode); sleep 1; done; done';
|
||||
|
||||
zk-2 Mode: follower
|
||||
zk-0 Mode: follower
|
||||
zk-1 Mode: leader
|
||||
zk-2 Mode: follower
|
||||
```
|
||||
|
||||
Delete Pods and wait for the StatefulSet controller to bring them back up:
|
||||
```console
|
||||
$ kubectl delete po -l app=zookeeper
|
||||
$ kubectl get po --watch-only
|
||||

|
||||
zookeeper-2 1/1 Running 0 41s
|
||||
```
|
||||
|
||||
Check the previously inserted key:
|
||||
```console
|
||||
$ kubectl exec zookeeper-1 -- bin/zkCli.sh get /foo
|
||||
ionid = 0x354887858e80035, negotiated timeout = 30000

|
||||
bar
|
||||
```
|
||||
|
||||
## Scaling
|
||||
ZooKeeper can not be safely scaled in versions prior to 3.5.x
|
||||
|
||||
## Limitations
|
||||
* Only supports storage options that have backends for persistent volume claims.
