Quoting from the rancher docs
"For true HA, a replicated MySQL database with proper backups is recommended. Using Galera and forcing writes to a single node, due to transaction locks, would be an alternative."
- Does this mean that mysql should be configured for master slave mode ?
- If we plan to use galera then do we need to configure write to single node rather than master master configuration ?
- Can we use mariadb instead of mysql ?
