Examples

---
# 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
# M(proxysql_manage_config) module).  It uses supplied credentials to connect
# to the proxysql admin interface.

- 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.  It uses
# credentials in a supplied config file to connect to the proxysql admin
# interface.

- proxysql_replication_hostgroups:
    config_file: '~/proxysql.cnf'
    writer_hostgroup: 3
    reader_hostgroup: 4
