Using handlers and specifying the notify: reboot

Question

Using handlers and specifying the notify: reboot

Closed this issue 2 years ago · 2 comments

Since you are using handlers, the notify: reboot is going to happen at the end of the play. Since the handler is only going to run once when the play has ended no need to call it multiple times.

if you need handlers to run before the end of the play, add a task to flush them using the meta module which executes ansible actions. More details: https://docs.ansible.com/ansible/latest/user_guide/playbooks_handlers.html#controlling-when-handlers-run

The meta: flush_handlers task triggers any handlers that have been notified at that point in the play. Mind you since this is a reboot your gonna have to get your env to wait before proceeding if you need to flush prior to end of play.

This also applies for notify: restart container service in https://github.com/hybrid-cloud-patterns/ansible-edge-gitops/blob/main/ansible/roles/container_lifecycle/tasks/main.yml

Thanks - I I think the reboot is OK where it is. In the original demo, the reboot was at the end of the play - I'm refactoring a bit to make it so the code is more idempotent. The mechanism for reboot as a handler has tested successfully so far.
