Fork, make your changes, then make a pull request.

You can use your own Jekyll install but to make testing with a consistent environment easier, a container image is available. If you use docker, alias podman="docker".

Assuming that the repository has been cloned into ~/linux-ph, run the Jekyll container with podman run --rm --publish 4000:4000/tcp --publish 35729:35729/tcp --volume ~/linux-ph:/var/www and go to http://localhost:4000/.

The container runs jekyll server --host --livereload by default. You can override this by supplying different arguments. To build the site manually for example, you can execute podman run --rm --volume ~/linux-ph:/var/www build

If you are using a system with SELinux enabled, mount the host directory with :Z e.g. --volume ~/linux-ph:/var/www:Z to relabel it. Alternatively, you can disable label confinement with --security-opt "label=disable".

Building the Jekyll image

$ cd ~/linux-ph
$ podman build --file --tag localhost/jekyll-build:latest ${PWD}
$ podman run --rm localhost/jekyll-build:latest > ruby-3.0.1-jekyll.tar.gz
$ podman build --file Containerfile --tag ${PWD}
