CentOS.org website

The CentOS.org website is using the following tools:

• jekyll 4
• bootstrap 4.
• podman (but should work with other know containers solutions too)

Contributing to changes to this repo

Needed tools

Just ensure that you have git, podman installed on your CentOS, Fedora workstation (or any other linux distro, just showing this as example):

sudo yum install slirp4netns podman git

Cloning this repo, from your forked version

You should first login with your ACO login on https://git.centos.org, and then fork this repo (if not already done)

Once done, you'll have to clone your fork locally, and submit changes. This section describes the steps you need to follow in order to render the final site using jekyll in Fedora 31/CentOS 8, with rootless container.

Let's assume the following (so feel free to update):

• git_upstream="ssh://git@git.centos.org/forks/<ACO_LOGIN>/centos/centos.org.git" # replace with your ACO username
• git_directory="$HOME/git/" # where you'll git clone git repo

Let's first clone git repo and ensure that some files in container will be owned by jekyll :

test -d ${git_directory} || mkdir -p ${git_directory}
pushd ${git_directory}
test -d centos.org || git clone ${git_upstream}

for i in .jekyll-cache vendor vendor/bundle _site ; do 
 podman unshare mkdir -p ${git_directory}/centos.org/${i}
 podman unshare chown -R 1000:1000 ${git_directory}/centos.org/${i}
done
podman unshare chown -R 1000:1000 ${git_directory}/centos.org/Gemfile.lock
popd

Let's now for the first time launch jekyll :

podman images |grep -q jekyll || podman run --volume="${git_directory}/centos.org:/srv/jekyll:z" --volume="${git_directory}/centos.org/vendor/bundle:/usr/local/bundle:z" --rm -it jekyll/jekyll bundle update

If that works, you'll have everything you need. You can then render/build the website (under _site directory) like this :

podman run --volume="${git_directory}/centos.org:/srv/jekyll:z" \
  --volume="${git_directory}/centos.org/vendor/bundle:/usr/local/bundle:z" \
  --rm -it jekyll/jekyll jekyll build

The better way to work on changes is to have jekylly to automatically "watch" for local changes, and rebuild automatically on the fly when it detects that files were added/modified. To do this, and then to be able to browse "live" onhttp://localhost:4000 , launch Jekyll like this :

podman run --volume="${git_directory}/centos.org:/srv/jekyll:z" \
  --volume="${git_directory}/centos.org/vendor/bundle:/usr/local/bundle:z" \
  -p 4000:4000/tcp \
  --rm -it jekyll/jekyll jekyll serve

Opening a PR (Merge request)

Once you're satisfied with local changes, proceed as usual :

• git commit and git push to origin (your fork)
• open PR on git.centos.org

Reviewing a PR (for admins)

When someone will open a PR, there is a way to pull locally the proposed changed and render locally. We can apply the method above with "jekyll serve" but we can pull locally. On each PR, there is a link at bottom named "Pull this pull-request locally" with a link to instructions. If you proceed, that will create a new temporary branch named pr<number>, so you can then git checkout pr<number> , render website automatically and see if that looks ok. If it is, you can go back to git.centos.org, and then either comment (if you need some changes) or just merge it. Merging it in main branch will automatically means that website will be rebuild and pushed in the next minute[s] to www.centos.org nodes.
