This is an example Ansible project that performs a set of use cases on a two node virtualization cluster.

The following playbooks are implemented:

• status.yml : Displays the current cluster status from pcs status
• setup.yml : Deploys and configures pacemaker and libvirt on the hosts in the "cluster_nodes" group
• cluster_update.yml: Updates the cluster nodes to the latest software packages available
• vm_deploy.yml : Deploys a virtual machine onto the cluster
• vm_delete.yml : Deletes a virtual machine from the cluster

Examples:

ansible-playbook -i hosts setup.yml

Installs and configures the cluster.

ansible-playbook -i hosts status.yml

Show the current cluster status.

ansible-playbook -e 'vm_name=db' -i hosts vm_deploy.yml

Update the cluster.

ansible-playbook -i hosts cluster_update.yml

Deploys a virtual machine named "db" onto the cluster.

ansible-playbook -e 'vm_name=db' -i hosts vm_delete.yml

Deletes a virtual machine named "db" from the cluster.

Configuration is in group_vars/all - add your satellite registration, nfs, and other information in there.

A number of assumptions are made about the environment currently:

• Systems will be registered to Satellite 6
• Storage is on NFS and guests are stored in a directory called "guests" within the NFS volume.
