Matrixtest-IaC-Ansible

This ansible playbook creates a three node cluster in openstack.

In this case a microk8s cluster.

The following tasks is executed by this playbook.

  • Creates a custom security group with rules to accept traffic between the nodes.
  • Create an os volume from the debian-12 image.
  • Create an snap volume to be used as an LVM volume for easy resize and mounted on /lib/snap.
  • Query all security groups in the project.
  • Create an network port for each node and use a selection of the queried security groups.
  • Create an instance with os volume, snap volume and port attached and a custom cloudinit config.

Cloudinit config.

Cloudinit does the following tasks.

  • Install tools for LVM2,XFS and the Chronyd ntp sevice.
  • Configure Chronyd to use netnod.se as a source.
  • Configure a lvol_snap LVM volume and format it with XFS.
  • Add a mount record of the lvm volume in fstab and verifies it.
