grunt-ansible-docs

A grunt plugin for generating documentation for Ansible from inline comments. It generates documentation for inventory groups, and variables read from both roles and group_vars.

Example

Given an inventory file inventory:

# The primary server 
[primary]
server1
 
# The replica server 
[replica]
server2

...a role with a default vars file at roles/myrole/defaults/main.yml:

# A role variable 
role_var: foo
 
# Another role variable 
second_role_var: bar

..and a group vars file group_vars/all.yml:

# A playbook variable 
play_var: one
 
# An override of the role var 
role_var: two

...running the following:

grunt ansible-docs

...would produce a JSON file at ansible_docs.json:

{
  "vars": {
    "play_var": { "description": "A playbook variable", "value": "one" },
    "role_var": { "description": "An override of the role var", "value": "two" },
    "second_role_var": { "description": "Another role variable", "value": "bar" }
  },
  "inventory": {
    "primary": { "description": "The primary server", "value": "server1" },
    "replica": { "description": "The replica server", "value": "server2" }
  }
}

This JSON file can then be further processed to generate a Markdown file, LaTeX document, HTML website, or whatever.

Getting Started

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-ansible-docs --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-ansible-docs');
