DevOps/Ansible/Modules

Modules add new capabilities to Ansible and is a core component of the software, as of September 2019 there are more than 2.800 modules available: ansible-doc --list. For example you can manage AWS infrastructure using Ansible, execute commands with shell module or collect information using setup module.

• ansible -m setup SERVER_NAME will collect information from your system
• ansible -m setup SERVER_NAME -a 'filter=ansible_distribution'. Collect just OS.

Other common useful modules include:

• Execution modules:
  • command, default for ad-hoc commands, bypasses the shell so won’t be impacted by local shell variables.
  • shell, allow to use shell functionalities such as redirection.
  • raw, do not require python on remote system
• gather_facts, lineinfile, user, group, mount, git, docker, docker_compose and mail modules, see all of them by category: https://docs.ansible.com/ansible/latest/modules/modules_by_category.html
