Ansible: Display variables and depend on changed
Show run time variable values for host
- name: display all variables and facts known for a host
ansible.builtin.debug:
var: hostvars[inventory_hostname]
Correct way of registering change on shelled out commands
- name: Handle shell output with return code
ansible.builtin.command: cat
register: my_output # <- Registers the command output.
changed_when: my_output.rc != 0
conditional when changed
- name: create systemd unit file
ansible.builtin.template:
dest: /path/to/foo
src: foo.j2
register: unit_file
- name: reload systemd daemon when unit file changed
ansible.builtin.systemd:
daemon_reload: true
when: unit_file.changed
