How do I use this?

Very simple.

1. ansible-galaxy install --force --roles-path=/where/ever/you/want/your/roles CaptTofu.galera

2. Add three galera hosts to your ansible hosts file

   [galera_cluster] host1 host2 host3

3. Use it in your playbook:

   • hosts:
     • galera_cluster roles:
     • CaptTofu.ansible-galera

4. Run your playbook (this is for Docker)

   ansible-playbook -i hosts -u root cluster.yml
