Generate documentation from annotated Ansible roles using templates
This project is based on the idea (and at some parts on the code) of ansible-autodoc by Andres Bott so credits goes to him for his work.
ansible-doctor is a simple annotation like documentation generator based on Jinja2 templates. While
ansible-doctor comes with a default template called
readme, it is also possible to write your own templates. This gives you the ability to customize the output and render the data to every format you like (e.g. html or xml).
ansible-doctor is designed to work within your CI pipeline to complete your testing and deployment workflow. Releases are available as Python Packages on GitHub or PyPI and as Docker Image on DockerHub.

Keep in mind, that you have to pass selinux labels (:Z or :z) to your mount option if you are working on a selinux enabled system.
ansible-doctor comes with default settings which should be sufficient for most users to start, but you can adjust most settings to your needs.
Changes can be made on different locations which will be processed in the following order (last wins):
- default config (build-in)
- global config file (path depends on your operating system)
- folder-based config file (.ansibledoctor.yml|.ansibledoctor.yaml|.ansibledoctor in current working dir)
- environment variables
- cli options

If you don't pass a folder to
ansible-doctor your current working directory will be used. The first step is to identify if the given folder is an ansible role. This check is very simple, if the folder contains a subfolder called
tasks is MUST be an ansible role! :)
After the successful check,
ansible-doctor will try to read some static files into a dictionary:
This will be the base result set which is used as data source for every output template. Without any work, you will get at least a documentation about available variables and some meta information. Theses basic information can be expanded with a set of available annotations. In general, an annotation is a comment with an identifier. This identifier is followed by colon separated options and ends with a value.
# @identifier option1:option2: <value> # @var docker_registry_password:example: "%8gv_5GA?" # @var docker_registry_password:description: Very secure password to login to the docker registry # @var docker_registry_password:description: > # You can also write it as multiline description # Very secure password to login to the docker registry. # @end docker_registry_password: "secret"
These list of pre-defined identifiers is currently available:
