The galera_server role now includes the functionality from the
galera_client role, and can optionally install the client and server
components. This is controlled using two booleans, galera_install_server
and galera_install_client, both of which default to false.
upgrade:
- |
The galera_server role now includes the functionality from the
galera_client role, and as a result a number of the variables from
the galera_client defaults are now available to override in the
galera_server role defaults. In addition, a number of default variables
have been generalised, removing the specific `_client_` or `_server_`
parts of the names. Users of this role should check that any overrides
they are using have the correct variables names for the new combined
role.
