Ansible: Rubrik

Run ansible commands from in the anbible/ folder to ensure that the ansible.cfg is used.

cd ansible

Test connectivity to the hosts:

ansible -m ping rubrik-*

Run the Ansible playbook for the rubrik environment:

ansible-playbook configure.yml

:::info For testing on a limited subset of hosts in an environment, use -l <host-fqdn>.

ansible-playbook configure.yml -l rubrik-[abd].maas.home.morey.tech

:::

After running the playbook, generate a cluster join command on the "primary" node (default rubrik-a) for each additional node:

ansible rubrik-a.maas.home.morey.tech -a "microk8s add-node"

Copy the generated microk8s join command in the output and run it on the other host to join it to the cluster:

ansible rubrik-<n>.maas.home.morey.tech -a "microk8s join 192.168.3.17:25000/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/xxxxxxxxxx"

Confirm that the nodes are clustered together:

ansible rubrik-a.maas.home.morey.tech -a "microk8s status"

The expect status is:

microk8s is running
high-availability: yes
  datastore master nodes: 192.168.3.xx:19001 192.168.3.xx:19001 192.168.3.xx:19001
  datastore standby nodes: none

Reset Microk8s to a fresh install

ansible rubrik-[abcd]* -a "microk8s leave" -b
ansible rubrik-[abcd]* -a "microk8s reset" -b
