Have ansible playbook wait until host is active

Question

I am looking to run a playbook that checks if a host is active, and if not check again in 24 hours.

start playbook

    do while host X is not up
    {
        wait 24 hours
    }

Is this possible in ansible? From the docs, it's very unclear if it is.

possibly a common and duplicated question https://stackoverflow.com/a/23888382/338011 need clarification and code. — Baptiste Mille-Mathias, Jul 18 '18 at 13:16

You can use Ansible's wait_for module.

- name: Wait for host
  wait_for:
    host: "{{ inventory_hostname }}"
    port: 22
    sleep: 86400     # check every 24 hours
    timeout: 604800  # exit after 7 days
  delegate_to: localhost

In case you are not waiting for a reboot, but the initial boot, the parameter `gather_facts: no` is helpful. This should be set on the same indentation level as `wait_for`, but even better would be `wait_for_connection`.
