This issue affects

  • The site generated by GitHub Pages
  • Building sites locally

What did you do (e.g., steps to reproduce)

Attempting to use the github-pages gem using the docker image with the instructions from the README does not work out-of-the-box, for example:

git clone https://github.com/github/pages-gem
cd pages-gem
git checkout v228
docker build -t gh-pages .
cd ..
git clone https://github.com/github/personal-website
cd personal-website
docker run --rm -it -p 4000:4000 -v ${PWD}:/src/site gh-pages

What did you expect to happen?

To be able to run the site locally at localhost:4000

What happened instead?

I got the following error:

Additional information

The only way I could get it working was by running bundle install before jekyll serve:

docker run --rm -it \
    -p 4000:4000 \
    -v ${PWD}:/src/site \
    gh-pages \
    sh -c "bundle install && jekyll serve -H 0.0.0.0 -P 4000"

Shouldn't the github-pages gem be already preinstalled in the docker image?

After updating to the latest version of the pages-gem (v229), the Docker image was updated to Ruby 3 and fails because of issue #752. To work around this you now also need to run bundle add webrick before jekyll serve:

docker run --rm -it \
    -p 4000:4000 \
    -v ${PWD}:/src/site \
    gh-pages \
    sh -c "bundle add webrick && bundle install && jekyll serve -H 0.0.0.0 -P 4000"
