A task is nothing more than a module that calls ansible, variables can be used in the module parameters; the module execution is idempotent, which means that multiple executions are safe because the results are consistent;

Extra variablesYou may have seen in our template example in the previous chapter that we used avariable called group_names . This is one of the magic variables that are provided byAnsible it
() results = super(ActionModule, self).run(tmp, task_vars) # remove as modules might hide due to nolog del results['invocation']['module_args'] results = merge_hash(results, self._execute_module(tmp=tmp, task_vars=task_vars)) # Remove special fields from the result, which can only be set # internally by the executor engine. We do this only here in # the 'normal' action, as other action plugins may set this. # # We don't want modules

Finding files with variablesAll modules can take variables as part of their arguments by dereferencing themwith {{ and }} . You can use this to load a particular file based on a variable.For example, you might want to select a different config file for NRPE (a Nagioscheck daemon) based on the architecture in use. Here is how that would look:---#1- name: Configure NRPE for the right architecture#2hosts: ansibletest#3user: root#4tasks:#5
