mkdocs uses a markdown renderer that is hardcoded to 4 spaces per tab
for detecting indentation levels, including ordered- and
unordered-lists. Since we cannot easily change the renderer, begin using
a markdown linter in CI that will fail if official docs do not adhere to
the spacing rules.
As a starting point, the markdownlint config does not begin with the
default set of checks, which might overwhelm attempts to fix them.
Instead, focus on list-tab-spacing rules and a few other highly useful
checks.
markdownlint also has some gaps in its abilities that allow common Rook
doc issues to pass acceptance. However, it allows creating custom
linting plugins. Create 2 such linting plugins to check 2 things:
- all doc lines (except code blocks) must be aligned to a 4-space
boundary, without exception. This ensures that markdown will render
correctly with mkdocs. This unfortunately makes it possible to create
lists that are internally aligned strangely.
- admonitions must all follow the same format of
```
!!! header
body
```
For the strange lists, this is allowed and renders correctly, but it
looks strange:
```md
- first bullet
- second bullet
still second bullet
- third bullet
has a paragraph
of text inside
- last bullet

We are using MkDocs with the Material for MkDocs theme.
Markdown Extensions
Thanks to the MkDocs Material theme we have certain "markdown syntax extensions" available:
For a whole list of features Reference - Material for MkDocs.
Local Preview
To locally preview the documentation, you can run the following command (in the root of the repository):
make docs-preview
When previewing, now you can navigate your browser to http://127.0.0.1:8000/ to open the preview of the documentation.
!!! hint
Should you encounter a command not found error while trying to preview the docs for the first
time on a machine, you probably need to install the dependencies for MkDocs and extensions used:
pip3 install -r build/release/requirements_docs.txt. Make sure that your Python binary path is
included in your PATH.
Making docs
helm-docs is a tool that generates the documentation for a helm chart automatically. If there are changes in the helm chart, the developer needs to run make docs (to run helm-docs) and check in the resulting autogenerated files.
To make it easy to check locally for uncommitted changes generated by make docs, an additional make target exists: simply running make check-docs will run the docs auto-generation and will complain if this produces uncommitted changes to doc files. It is therefore a good habit to always run make check-docs locally before creating or updating a PR.
