[BenMayden]

SUMMARY

The "community.proxysql.proxysql_mysql_users" module does not support adding comment to the comment column of the mysql_users table.

ISSUE TYPE

• Feature Idea

COMPONENT NAME

community.proxysql.proxysql_mysql_users

ADDITIONAL INFORMATION

The mysql_users table has a "comment" column, however, the "community.proxysql.proxysql_mysql_users" module does not support the comment parameter, and so it cannot add a comment to the comment column for a user.

- name: Add a user with a comment
  community.proxysql.proxysql_mysql_users:
    config_file: /some/file/path
    username: user
    password: secretpass
    comment: "Ansible Managed User" <--- This would be a useful parameter
    default_hostgroup: 1
    state: "{{ item.proxysql_state }}"
