3.1 - List

3.2 - Run

  • With ansible, example running a module
ansible all -i sub.example.net, -m moduleToRun 

where:

  • all is the host group(s) to which the command should apply (in this case, all)
  • the inventory (-i, the device or devices to target - without the trailing comma -i points to an inventory file)
  • the module (-m, the ansible module to run)

4 - Types

Name New / Old Style Module Note
Action plugins Take actions before executing a module
Python New-style
Powershell New-style Written with the powershell module framework
Binary modules
Want JSON modules Get a JSON file with the module parameters (Non-native module)
JSONARGS Replace a placeholder in the script with the parameters of the module
Old-style modules similar to want JSON modules, except that the file that they take contains key=value pairs for their parameters instead of JSON.
Ansible decides that a module is old-style when it doesn’t have any of the markers that would show that it is one of the other types.

All official modules (shipped with Ansible) use either Ansiballz framework or the powershell module framework.

New-style modules - All of the modules that ship with Ansible fall into this category. - New-style modules have the arguments to the module embedded inside of them in some manner whereas Non-new-style modules must copy a separate file over to the managed node, which is less efficient as it requires two over-the-wire connections instead of only one.
