  • Main Ansible documentation page
  • Ansible Getting Started
  • Tower User Guide
  • Ansible Community Info

• Functioning Ansible and/or Tower Installed, configured, and running. This includes all of the base Ansible/Tower configurations, needed packages installed, and infrastructure setup.

Also familiarize yourself with the variables in the defaults/main.yml file or the Main Variables Wiki Page.

Documentation

• Repo GitHub Page
• Getting Started
• Customizing Roles
• Per-Host Configuration
• Getting the Most Out of the Role
• Wiki

Dependencies

The following packages must be installed on the controlling host/host where ansible is executed:

• python2-passlib (or just passlib, if using python3)
• python-jmespath

Package 'python-xmltodict' is required if you enable the OpenSCAP tool installation and run a report. Packages python(2)-passlib and python-jmespath are required for tasks with custom filters or modules. These are all required on the controller host that executes Ansible.

Role Variables

This role is designed that the end user should not have to edit the tasks themselves. All customizing should be done via the defaults/main.yml file or with extra vars within the project, job, workflow, etc. These variables can be found here in the Main Variables Wiki page. All variables are listed there along with descriptions.

Tags

There are many tags available for added control precision. Each control has it's own set of tags noting the control number as well as what parts of the system that control addresses.

Below is an example of the tag section from a control within this role. Using this example if you set your run to skip all controls with the tag ssh, this task will be skipped. The opposite can also happen where you run only controls tagged with ssh.

tags:
    - CISC-L2-000010
    - ip_interfaces
    - motd_banner
