This project is based on the idea (and at some parts on the code) of [ansible-autodoc](https://github.com/AndresBott/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](https://github.com/xoxys/ansible-doctor/releases) or [PyPI](https://pypi.org/project/ansible-doctor/) and as Docker Image on [DockerHub](https://hub.docker.com/r/xoxys/ansible-doctor).

### Setup
|
||||
|
||||
#### Using pip
|
||||
|
||||
```Shell
|
||||
# From PyPI as unprivilegd user
|
||||
$ pip install ansible-doctor --user
|
||||
|
||||
# .. or as root
|
||||
$ sudo pip install ansible-doctor
|
||||
|
||||
# From Wheel file
|
||||
$ pip install https://github.com/xoxys/ansible-doctor/releases/download/v0.1.1/ansible_doctor-0.1.1-py2.py3-none-any.whl
|
||||
```
|
||||
|
||||
#### Using docker
|
||||
|
||||
```Shell
|
||||
docker run \
|
||||
-e ANSIBLE_DOCTOR_ROLE_DIR=example/demo-role/ \
|
||||
-e ANSIBLE_DOCTOR_OUTPUT_DIR=example/ \
|
||||
-e ANSIBLE_DOCTOR_FORCE_OVERWRITE=true \
|
||||
-e ANSIBLE_DOCTOR_CUSTOM_HEADER=example/demo-role/HEADER.md \
|
||||
-e ANSIBLE_DOCTOR_LOG_LEVEL=info \
|
||||
-e PY_COLORS=1 \
|
||||
-v $(pwd):/doctor \
|
||||
-w /doctor \
|
||||
xoxys/ansible-doctor
|
||||
```
|
||||
|
||||
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.
|
||||
|
||||
### Configuration
|
||||
|
||||
`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
|
||||
|
||||
#### Default settings
|
||||
|
||||
```YAML
|
||||
---
|

dry_run: False
|
||||
|
||||
logging:
|
||||
# possible options debug | info | warning | error | critical
|
||||

|
||||

|
||||
# load custom header from given file and append template output
|
||||
# to it before write.
|
||||
custom_header: ""
|
||||
|
||||
exclude_files: []
|
||||
# Examples

|
||||
|
||||

|
||||

|
||||

```
|
||||
|
||||
### Usage
|
||||
|
||||
```Shell
|
||||
ansible-doctor FOLDER
|
||||
```
|
||||
|
||||
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:
|
||||
|
||||
* defaults/main.yml
|
||||
* meta/main.yml
|
||||
|
||||
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.
|
||||
|
||||
```Yaml
|
||||
# @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:
|
||||
|
||||
* @meta
|
||||
* @todo
|
||||
* @var
|
||||
* @tag
