You can test the changes to this repository via a container.

Run a Jekyll container

• Clone repository, check out source branch and prepare the Jekyll site

  git clone -b source https://github.com/redhat-cop/openshift-migration-best-practices.git && cd openshift-migration-best-practices
  for i in .jekyll-cache _site; do mkdir ${i} && chmod 777 ${i}; done
  for i in Gemfile.lock; do touch ${i} && chmod 777 ${i}; done

• On a SELinux enabled OS:

  podman run -it --rm --name jekyll -p 4000:4000 -v $(pwd):/srv/jekyll:Z jekyll/jekyll jekyll serve --watch --future

  NOTE: The Z at the end of the volume (-v) will relabel its contents so that it can be written from within the container, like running chcon -Rt svirt_sandbox_file_t -l s0:c1,c2 yourself. Be sure that you have changed your present working directory to the git cloned directory as shown above.

• On an OS without SELinux:

  podman run -it --rm --name jekyll -p 4000:4000 -v $(pwd):/srv/jekyll jekyll/jekyll jekyll serve --watch --future
