Debug Module Returns "Hello, World!" when a message is specified.

[Philip Gregory]

Using Ansible 2.4.2.0 on Ubuntu 16.04, I try running a plaubook with the following:

- name: Create repo line in Ubuntu/Debian

command: bash -c "echo \"deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable\" "

register: docker_repo_line

when:

ansible_distribution == 'Debian'

or

ansible_distribution == 'Ubuntu'

- debug:

msg: "{{ docker_repo_line.stdout }}"

when:

ansible_distribution == 'Debian'

or

ansible_distribution == 'Ubuntu'

- name: Add Docker Repo on Ubuntu/Debian

apt_repository:

repo: "{{ docker_repo_line.stdout }}"

state: present

when:

ansible_distribution == 'Debian'

or

ansible_distribution == 'Ubuntu'

However, the Debig Module set the message as "hello, world" when I run the command. Looking at the module documentation, this is the default if no msg is specified. However, I do I have line for hte message. Am I missing something here?

My guess is all the module results are contained in a key called 'results' within the var that you registered.

Try this

- debug:
var: "{{ docker_repo_line }}"

I suspect that the bit you want is in
- debug:
msg: "{{ docker_repo_line.results.stdout }}"

But try inspecting the whole of the var. If there is a lot of output, use something like Jsonlint.com to pretty print the json so that you can get a clearer idea of what is being returned.

Hope this helps,
