The complete Ansible tree is documented using the MKDocs documentation system. All documentation is done in MarkDown, with a bit of MKDocs flavour added.
And as all documentation is in Markdown with the
mkdocs flavour, the mkdocs package needs to
be installed.
pip install markdown
pip install mkdocs
Every Ansible role has the complete documentation in it's own README.md file
and these README.me files are gathered with the bin/refresh script.
This way the documentation is in the role and chances are it is kept up to date.
Viewing the documentation can be done in multiple ways, which are all web-based.
- Internal webserver
- External webserver
The mkdocs command contains an integrated webserver, that can be started
with:
mkdocs serve
Now you can point your browser to the documentation site: http://docserver:8000
When you already have a webserver, this can be used to display all documentation. Of course you can create a separate virtual host or just host the documentation in a separate directory.
The command
mkdocs build
creates a complete tree of all documentation in the site directory.
To run MKDocs as a service create a systemd service file in
/etc/systemd/system/mkdocs.service containing
[Unit]
Description=MKDocs
After=network.target
[Service]
Type=simple
User=root
Group=root
TimeoutStartSec=0
Restart=on-failure
RestartSec=10
RemainAfterExit=yes
WorkingDirectory=/etc/ansible/roles/docs
ExecStart=/bin/mkdocs serve
[Install]
WantedBy=multi-user.target
And enable and start the service
systemctl daemon-reload
systemctl enable mkdocs
systemctl start mkdocs
And open the firewall
firewall-cmd --add-port=8000/tcp --permanent
firewall-cmd --reload
There is something weird with the fontawesome-webfont font package.
On CentOS the file fontawesome-webfont.svg is missing. This file
is placed in the fonts directory and should be copied to the
/usr/share/fonts/fontawesome directory on the server running MKDocs.
