ansible – How to Print Debug Message Variable

ansibledeployment

I try to print the previously registered mosh_version variable using the ansible debug msg command like this:

- name: Print mosh version
  debug: msg="Mosh Version: {{ mosh_version.stdout }}"

It doesn't work and prints the following error:

Note: The error may actually appear before this position: line 55, column 27

- name: Print mosh version
  debug: msg="Mosh Version: {{ mosh_version.stdout }}"
                          ^
We could be wrong, but this one looks like it might be an issue with
missing quotes.  Always quote template expression brackets when they
start a value. For instance:

    with_items:
      - {{ foo }}

Should be written as:

    with_items:
      - "{{ foo }}"

I tried 

- name: Print mosh version
  debug: msg=Mosh Version: "{{ mosh_version.stdout }}"

but this will just print "Mosh".

What's the best way to get this running?

Best Answer

Try this:

- name: Print mosh version
  debug: "msg=Mosh Version: '{{ mosh_version.stdout }}'"

Edited: Something like this works perfect for me:

- name: Check Ansible version
  command: ansible --version
  register: ansibleVersion

- name: Print version
  debug:
    msg: "Ansible Version: {{ ansibleVersion.stdout }}"
