  gather_facts: yes

  roles:
    - role: buluma.keepalived
      keepalived_vrrp_instances:
        - name: VI_1
          state: MASTER
          interface: eth0
          unicast_src_ip: "172.17.0.6"
          secondary_private_ip: "172.17.0.7"
          virtual_router_id: 51

# default settings for keepalived

# You will need to configure it yourself. Check `molecule/default/converge.yml` for an example.
# All nodes can be set to BACKUP unless you want to start one as MASTER.
# You can see virtual IP configuration using `ip addr list eth0`.
