ansible.builtin.systemd_service module – Manage systemd units
Note
This module is part of ansible-core and included in all Ansible
installations. In most cases, you can use the short
module name
systemd_service even without specifying the collections keyword.
However, we recommend you use the Fully Qualified Collection Name (FQCN) ansible.builtin.systemd_service for easy linking to the
module documentation and to avoid conflicting with other collections that may have
the same module name.
Synopsis
Controls systemd units (services, timers, and so on) on remote hosts.
ansible.builtin.systemd is renamed to ansible.builtin.systemd_service to better reflect the scope of the module. ansible.builtin.systemd is kept as an alias for backward compatibility.
Aliases: systemd

Notes
Note
Before 2.4 you always required
name.Globs are not supported in name, in other words,
postgres*.service.The service names might vary by specific OS/distribution.
The order of execution when having multiple properties is to first enable/disable, then mask/unmask and then deal with the service state. It has been reported that
systemctlcan behave differently depending on the order of operations if you do the same manually.
