Systemd Timer¶

Description¶

This role configures a systemd timer to periodically start a corresponding service. It uses a Jinja2 template to create a timer unit file that specifies the scheduling parameters (such as OnCalendar and RandomizedDelaySec) and then restarts the timer service accordingly.

Overview¶

Optimized for automated task scheduling in a systemd environment, this role: - Generates a timer unit file for a given service (using the system_service_timer_service variable). - Reloads and restarts the timer using systemd to ensure that changes take effect. - Supports dynamic configuration of scheduling parameters via variables like system_service_on_calendar and RANDOMIZED_DELAY_SEC.

Purpose¶

The primary purpose of this role is to provide a reusable mechanism for scheduling recurring tasks on a system. By creating and managing a systemd timer unit, the role ensures that specified services are automatically started at defined intervals, enhancing system automation and reliability.

Features¶

Dynamic Timer Configuration: Uses a Jinja2 template to create a timer unit file based on provided variables.
Automated Service Management: Automatically reloads the systemd daemon and restarts the timer when changes are detected.
Flexible Scheduling: Supports configuration of parameters such as OnCalendar and RandomizedDelaySec for precise control over task timing.
Persistent Timers: Optionally enables persistent timer behavior to ensure missed activations are handled.
