Move sanitarium masters to dedicated puppet role
Closed, ResolvedPublic


Currently the sanitarium masters use role::mariadb::core. This makes it ~impossible to distinguish them on an automation level. If we duplicate role::mariadb::core (and make the default binlog format be ROW while we're at it), this will simplify things.

E.g. is something that could be autogenerated if we could identify sanitarium masters at a puppet level.
