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:

      - {{ foo }}

Should be written as:

      - "{{ 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?


Try this:

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

More info in http://docs.ansible.com/YAMLSyntax.html#gotchas

Edited: Something like this works perfect for me:

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

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

  • There are no more syntax errors, but it doesn't work either: TASK: [ Print mosh version] ************************************** ok: [] => { "msg": "Mosh" } – Zulakis Jun 1 '15 at 12:23
  • Try first just print variable and see output without custom message, like this: - name: Print mosh version debug: var=mosh_version.stdout_lines – Tom Aac Jun 1 '15 at 12:30
  • ok: [] => { "var": { "mosh_version.stdout_lines": [ "mosh 1.2.4a [build mosh-1.2.4-57-g9eeb2fb]" ] } } this works, I'd really prefer the custom message though ;-) – Zulakis Jun 1 '15 at 12:37

    Please note: debug: "msg=Mosh Version: '{{ mosh_version.stdout }}'" will display only "Mosh". The msg="..." must be in quotes, instead of the whole message. But answer from @xddsg works better, as it is more detailed var dump. – Dalibor Filus Nov 26 '15 at 14:42

Simplest answer

- debug: var=mosh_version.stdout

Just remove the colon

debug: msg="Mosh Version {{ mosh_version.stdout }}"

  • Honestly, this is not a full solution but still it worked and solved the next issue I had. Can't use the other syntax because I use it with when so removing the colon actually is the simplest way to solve this. so I upvote ;) – TecHunter Oct 27 '16 at 9:48

I use this, notice the location of double quotes(") and single quotes(')

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

Anytime I have problems with special characters in Ansible strings/cmds I do this:

  1. Wrap with single quotes
  2. Wrap with double curly brackets

So your standard colon becomes {{':'}}

And your task becomes:

- debug: msg="Ansible Version{{':'}} {{ ansibleVersion.stdout }}"

Again this works for most special characters, even strings. Consider the following:

docker ps --format '{{.Names}}'

In order to run this in Ansible, just apply the same logic, the following task executes as expected:

- name: Get the docker container names
  become: yes
  shell: "docker ps --format '{{'{{'}}.Names{{'}}'}}'"
  register: docker_containers

I have displayed variable and message in the debug same task.

Ansible Task

- name: Report the /boot/initramfs file status for latest installed kernel
    msg: "{{ ansible_hostname }} =  {{INITRAMFS_LAST_KERNEL.stdout}}"


TASK [os-upgrade.linux : Report the /boot/initramfs file status for latest installed kernel] *******************************************
ok: [IEEMEANSBL1A] => {
    "msg": "IEEMEANSBL1A =  /boot/initramfs-3.10.0-1062.12.1.el7.x86_64.img"
