Examples

---
# This example adds a schedule, it saves the scheduler config to disk, but
# avoids loading the scheduler config to runtime (this might be because
# several servers 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_scheduler:
    login_user: 'admin'
    login_password: 'admin'
    interval_ms: 1000
    filename: "/opt/maintenance.py"
    state: present
    load_to_runtime: False

# This example removes a schedule, saves the scheduler config to disk, and
# dynamically loads the scheduler config to runtime.  It uses credentials
# in a supplied config file to connect to the proxysql admin interface.

- proxysql_scheduler:
    config_file: '~/proxysql.cnf'
    filename: "/opt/old_script.py"
    state: absent
