To implement conditions in Ansible, we use the when keyword. The keyword takes Boolean expressions based on a value or a variable from previous tasks or facts gathered from the remote hosts. This guide will teach you how to implement conditions in Ansible playbooks using the when keyword.
This module allows setting new variables. Variables are set on a host-by-host basis just like facts discovered by the setup module. These variables will be available to subsequent plays during an ansible-playbook run.
As per latest Ansible Version 2.5, to check if a variable is defined and depending upon this if you want to run any task, use undefined keyword. tasks: - shell: echo "I've got '{{ foo }}' and am not afraid to use it!" when: foo is defined - fail: msg="Bailing out. this play requires 'bar'" when: bar is undefined.
If variable1 is a string, and you are searching for a substring in it, this should work:
when: '"value" in variable1' if variable1 is an array or dict instead, in will search for the exact string as one of its items.
