# Ansible AWX Template: Template
|
||
|
|
||
|
Ansible AWX is the method used for the Rocky Linux infrastructure, as a replacement for using the CLI. This template should be copied, as to manage playbooks and tasks into reproducible, repeatable, and organized manner.
|
||
|
|
||
|
## Provides / Information
|
||
|
|
||
|
This repository is for AWX templates.

## Guidelines
|
||
|
|
||
|
These are the general guidelines for creating and maintaining these repositories. Please read carefully to ensure that you are meeting the criteria.
|
||
|
|
||
|
1. Copy this template into a new repository with the format `ansible-type-usage`. For example, if this is for ipa management, you could use a name like `ansible-ipa-management`.
|
||
|
2. Change the top of the `README.md` from "Template" to an appropriate name for your repo.
|
||
|
3. Modify the `README.md` file at the Provides/Information section of what these tasks do. Please be descriptive and list all of the playbooks and accompanying tasks (see the example). Hint: Use the `tree` command.
|
||
|
4. List any requirements to run the playbooks, such as vars, mandatory or optional in playbooks. Optionally, you may list them in the `README.md` here.
|
||
|
5. Run `pre-commit install` - There is already a provided `.pre-commit-config.yaml` with some default settings.
|
||
|
6. (Optional) Remove everything starting at "Guidelines" in this README to reduce clutter.
|
||
|
|
||
|
## Designing Playbooks
|
||
|
|
||
|
Generally, your playbooks should be doing the following:
|
||
|
|
||
|
1. Checking if ansible can be ran on a specific host
|
||
|
2. Asserting if variables are filled and are correctly formed
|
||
|
3. Importing tasks from the `./tasks` directory
|
||
|
4. Importing roles, if necessary
|
||
|
5. Post tasks, if necessary
|
||
|
|
||
|
**Note**: At no point should you be using `./tasks/main.yml`
|
||
|
|
||
|
### Pre-flight and Post-flight tasks
|
||
|
|
||
|
```
|
||
|
pre_tasks:
|
||
|
- name: Check if ansible cannot be run here
|
||
|
stat:
|
||
|
path: /etc/no-ansible
|
||
|
register: no_ansible
|
||
|
|
||
|
- name: Verify if we can run ansible
|
||
|
assert:
|
||
|
that:
|
||
|
- "not no_ansible.stat.exists"
|
||
|
success_msg: "We are able to run on this node"
|
||
|
fail_msg: "/etc/no-ansible exists - skipping run on this node"
|
||
|
|
||
|
# Assertions and other checks here
|
||
|
|
||
|
# Import roles/tasks here
|
||
|
|
||
|
post_tasks:
|
||
|
- name: Touching run file that ansible has ran here
|
||
|
file:
|
||
|
path: /var/log/ansible.run
|
||
|
state: touch
|
||
|
mode: '0644'
|
||
|
owner: root
|
||
|
group: root
|
||
|
```
|
||
|
|
||
|
### Comments
|
||
|
|
||
|
Each playbook should have comments or a name descriptor that explains what the playbook does or how it is used. If not available, README-... files can be used in place, especially in the case of adhoc playbooks that take input. Documentation for each playbook/role does not have to be on this wiki. Comments or README's should be sufficient.
|
||
|
|
||
|
### Tags
|
||
|
|
||
|
Ensure that you use relevant tags where necessary for your tasks.
|
||
|
|
||
|
### Playbook naming
|
||
|
|
||
|
```
|
||
|
init-* -> Starting infrastructure playbooks that run solo or import other
|
||
|
playbooks that start with import-
|
||
|
adhoc -> These playbooks are one-off playbooks that can be used on the CLI or
|
||
|
in AWX. These are typically for basic tasks.
|
||
|
import -> Playbooks that should be imported from the top level playbooks
|
||
|
role-* -> These playbooks call roles specifically for infrastructure tasks.
|
||
|
Playbooks that do not call a role should be named init or adhoc based
|
||
|
on their usage.
|
||
|
```
|
||
|
|
||
|
### Pre-commits / linting
|
||
|
|
||
|
When pushing to your own forked version of this repository, pre-commit must run to verify your changes. They must be passing to be pushed up. This is an absolute requirement, even for roles.
|
||
|
|
||
|
When the linter passes, the push will complete and you will be able to open a PR.
|
||
|
|
||
|
## How are these repositories used?
|
||
|
|
||
|
These repositories are generally cloned/pulled into AWX for the latest version, so they can be called within AWX either by hand or at a scheduled time.
