systemd service manager Ansible role

This is an Ansible role which manages systemd services.

Features

• starting (restarting) services, in order, according to their priority. Services can all be stopped cleanly and then started anew, or they can be restarted one-by-one (see devture_systemd_service_manager_service_restart_mode)

• making services auto-start (see devture_systemd_service_manager_services_autostart_enabled)

• verifying services managed to start (see devture_systemd_service_manager_up_verification_enabled)

• stopping services, in order, according to their priority

• starting/stopping all defined services, or a group of services (--tags=restart-group, --tags=stop-group)

• restarting services by cleanly stopping them and restarting them, or one by one

Usage

Example playbook:

- hosts: servers
  roles:
    - when: devture_systemd_service_manager_enabled | bool
      role: galaxy/com.devture.ansible.role.systemd_service_manager

Example playbook configuration (group_vars/servers or other):

# See `devture_systemd_service_manager_services_list_auto` and `devture_systemd_service_manager_services_list_additional`
devture_systemd_service_manager_services_list_auto: |
  {{
    ([{'name': 'some-service.service', 'priority': 1000}])
    +
    ([{'name': 'another-service.service', 'priority': 1500}])
  }}

Example playbook invocations tags (e.g. ansible-playbook -i inventory/hosts setup.yml --tags=XXXXX):

• restart, restart-all, start-all - restarts all services and potentially makes them auto-start (depending on devture_systemd_service_manager_services_autostart_enabled)

• restart-group, start-group - restarts services belonging to the specified group (e.g. --extra-vars="group=core")

• stop, stop-all - stops all services

• stop-group - stops services belonging to the specified group (e.g. --extra-vars="group=core")
