centos-jekyll-sites

Community effort to redesign CentOS websites using jekyll 4 and bootstrap 4.

Installation

This section describes the steps you need to follow in order to render the final site using jekyll in Fedora 31.

  1. Clone this repository:

    ]$ git clone https://git.stg.centos.org/centos/centos.org.git

  2. Download jekyll container:

    ]$ podman pull jekyll/jekyll

  3. Create an alias to run jekyll container by adding the following line to ~/.bashrc:

    ]$ alias jekyll='podman run --volume="$PWD:/srv/jekyll:z" --volume="$PWD/vendor/bundle:/usr/local/bundle:z" -p 4000:4000/tcp --rm -it jekyll/jekyll jekyll'

  4. Reload the ./bashrc file:

    ]$ source ~/.bashrc

  5. Update directory permissions using the container user namespace uid (1000) and gid (1000). This is necessary for jekyll inside the container to be able of writing in the host filesystem through the specified volumes:

    ]$ podman unshare chown 1000:1000 centos.org

The permissions must be applied to all the files and directories jekyll reads and writes to (e.g., _site for the final site, vendor/bundle for bundle cache, .jekyll-cache, etc.). Once the files permission have been changed this way you will see them using a high number (e.g., 100999). This number is the subordinate uid and gid the host uses to related to container user namespace uid and gid (e.g., 1000).

  1. Create the vendor/bundle directory inside the centos-jekyll-site directory:

    ]$ podman unshare mkdir -p vendor/bundle

At this point you should be able to run the following:

]$ jekyll -v
ruby 2.6.5p114 (2019-10-01 revision 67812) [x86_64-linux-musl]
jekyll 4.0.0

The first time you run jekyll it takes some time downloading all the gems and dependencies it needs. After this first download, it behaves like a regular command.

Accessing the final site

To access the final site you need to be inside the repository directory structure, where the Gemfile is, and run the following:

]$ jekyll serve

Then visit the site accessing to http://127.0.0.1:4000 in your host.

Making changes

Operations like editing, copying, creating, moving and removing files owned by by jekyll container user namespace uid and gid must be executed using podman unshare <command> [arg]. Otherwise, you may have permission issues. For example, to edit jekyll main configuration, run the following command:

]$ podman unshare nvim _config.yml
