Ansible supports MariaDB with the mysql community module (as I understand). However MariaDB is not mentioned in the documentation, e.g. here: Community.Mysql — Ansible Community Documentation and here Database modules — Ansible Documentation .
In practice many users are running MariaDB, so it should be mentioned more explicitly. I suggest mentioning MariaDB in the community.mysql collection, changing the header in the list of database modules to “MySQL and MariaDB”, and mentioning MariaDB in each individual mysql module’s documentation - at least under Synopsis and Notes.
I can make a suggestion with a Pull Request for this, but I haven’t found the corresponding rst files in github - can somebody share a URL please?
