[ansible-project] Ternary or when in ansible

[Prady A]

Hi Ansible experts 

I am confused which one to use 

I want to subscribe US servers default but if the server is in UK I want to subscription should Point to UK capsule server..

If IS_UK= TRUE  

Subscription-manager <UK CAPSUSULE SERVER>

then 

Subscription-manager <US CAPSUSULE SERVER>

Regards

Is "Subscription-manager" a command you want to run, or part of a string you're trying to initialize, or are you trying to set a variable for later use?
Is "IS_UK" a variable you already have, or is the problem how to create or set "IS_UK" itself?

In other words, you've described very well what you want to do, but you haven't described at all the problem(s) you've encountered doing it with Ansible.

Hi TODD,

Thanks for your reply.

Yes I ve that variable(IS_UK= TRUE)
defined already  and it is coming from upstream.

Just need to the logic for efficient if then syntax in ansible.

Secondly subscription manager is shell command. 

Regards

Prady

Hi again 

For simplicity I thought to do like this. 

Current code

- name: Subscribe my repo

   shell: |

      subscription-manager register bla bla 

After 

- name: Subscribe US REPO 

   shell: |

      subscription-manager register US server

    When: 

        IS_UK = false

- name: Subscribe UK REPO

   shell: |

      subscription-manager register UK server

    When: 

        IS_UK = True 

Regards 

PD

I would use a helper variable to you can reuse in some places, for example in the task title:

  vars:
    IS_UK: false
    server: "{{ IS_UK | ternary('UK-server', 'US-server') }}"

  tasks:
    - name: "Subscribe to {{ server }} repo"
      ansible.builtin.shell:
        echo subscription-managed register {{ server }}
