The when condition in Ansible is used to control whether a task or a role should be executed. It evaluates an expression and runs the task only if the condition evaluates to true. This allows you to skip certain tasks based on the state of a variable or the result of a previous task. ...

Ansible supports conditional evaluations before executing a specific task on the target hosts. If the set condition is true, Ansible will go ahead and perform the task. If the condition is not true (unmet), Ansible will skip the specified task. ...

In Ansible, you can define conditions that will be evaluated before a task is executed. When a condition is not met, the task is then skipped. This is done with thewhenkeyword, which accepts expressions that are typically based on a variable or a fact. ...
