Potter Docs Generator

This repository contains the build tools, configuration, web framework, etc. for the generating the Potter docs. For site source content including documentation, see the /docs directory in the /gardener/potter-hub and /gardener/potter-controller repos. The repository of the generated website is /gardener/potter-docs. It is served via GitHub Pages.

Dev Setup

Prerequisites

• Python 3.8
• Hugo (should be installed in the same version as in the CI/CD container, see the website build script for the correct version)

Step 1

Clone all involved GitHub repositories to your local machine. Export the repo root directories via the corresponding environment variables.

$ git clone https://github.com/gardener/potter-hub
$ git clone https://github.com/gardener/potter-controller
$ git clone https://github.com/gardener/potter-docs
$ git clone https://github.com/gardener/potter-docsgen

export SOURCE_PATH="<path-to-potter-docsgen-repo>"
export POTTER_HUB_PATH="<path-to-potter-hub-repo>"
export POTTER_CONTROLLER_PATH="<path-to-potter-controller-repo>"
export POTTER_DOCS_PATH="<path-to-potter-docs-repo>"

Step 2

Create a Python virtual environment in the .ci directory and activate it. Then install the Python package gardener-cicd-libs via pip.

$ cd <path-to-potter-docsgen-repo>/.ci
$ virtualenv -p <path-to-python-3.8> env
$ source env/bin/activate
$ pip install gardener-cicd-libs

Depending on whether you want to work on the actual CI script or want to run the website with local changes, perform the actions described in the following sections.

Running the website with local changes

When you want to run the website with local changes in the potter-hub or potter-controller repos, you should run the website build script via the following command:

./build_website.py --skip-build-and-commit=True --include-current-version-only=True

This will copy the /docs directories from the local potter-hub and potter-controller repos into <potter-docsgen-repo-path>/hugo/content and generate some metadata for Hugo. It will only include the current version of the docs directories on your filesystem.

Now execute the following commands:

cd $SOURCE_PATH/hugo
hugo serve

This will startup a local HTTP server which Hugo uses to serve the website.

When perfoming changes in the /docs folder of the local potter-hub and potter-controller repos, you must rerun the website build script in order to sync the changes into the /hugo/content directory.

Sometimes it might also be necessary to stop hugo serve, manually delete the /docs directories from /hugo/content, rerun the website build script, and restart hugo serve.

Working on the website build script

When you want to work on the website build script, you should run the website build script via the following command:

./build_website.py

This will build the website, write the build output to the $POTTER_DOCS_PATH repo, and actually commit all changes to the repo. You therefore shouldn't push the $POTTER_DOCS_PATH repo to origin.
