conditional on a result using a fact as the condition

Hi All,

Ansible 2.8

Trying to do something like this:

  • name: task
    shell: blah blah
    register: shell_result

  • name: do if hostname is in result
    shell: blah blah
    when: shell_result.stdout.find(inventory_hostname)

so obviously the line " when: shell_result.stdout.find(inventory_hostname)" is the problem. I have tried a few things but dont know what is the best way to achieve this (and without getting jinja templating warnings when running)

btw “inventory_hostname” is an ansible fact with the hostname

Thanks for any help

Hi Ansible

Hi All,

  when: shell_result.stdout.find(inventory_hostname)

so obviously the line " when: shell_result.stdout.find(inventory_hostname)" is the problem. I have tried a few things but dont know what is the best way to achieve this (and without getting jinja templating warnings when running)

You provided ambiguous and/or incomplete information.
Instead of guessing what you mean, please tell clearly:

* what you are trying to achieve
* how you are doing this
* what errors/problems you encounter
* what the relevant tasks/playbooks/code/variables look like

Thx

Hi, apologies for the lack of clarity. Nonetheless i figured out my problem… here is the working sample of the concept I was struggling with (in this case matching a variable to the shell result).

  • name: something that outputs stuff
    shell: hostname
    register: shell_result

  • debug:
    var: shell_result.stdout

  • debug:
    var: ansible_hostname

  • name: if hostname is in output then do something
    debug:
    msg: HELLO
    when: ansible_hostname in shell_result.stdout
    # I couldnt get this conditional to work with .find “when: shell_result.stdout.find(ansible_hostname)”
