--- # This example adds a replication hostgroup, it saves the mysql server config # to disk, but avoids loading the mysql server config to runtime (this might be # because several replication hostgroup are being added and the user wants to # push the config to runtime in a single batch using the # community.general.proxysql_manage_config module). It uses supplied credentials # to connect to the proxysql admin interface. - name: Add a replication hostgroup community.proxysql.proxysql_replication_hostgroups: login_user: 'admin' login_password: 'admin' writer_hostgroup: 1 reader_hostgroup: 2 state: present load_to_runtime: False # This example removes a replication hostgroup, saves the mysql server config # to disk, and dynamically loads the mysql server config to runtime.
