Ansible Plugins

• Inventory Plugins
• Kubernetes Inventory
• Script Inventory
• Tower Inventory

Modules (also referred to as “task plugins” or “library plugins”) are discrete units of code that can be used from the command line or in a playbook task. Ansible executes each module, usually on the remote target node, and collects return values.
