Using docker.io/jekyll/jekyll:latest image (sha256:d5ce76846e2c4e037040d093954aae4441eb45e2e2ae4ff84cd7aeca6e694b28) to run the jekyll serve command fails with the following:

The jekyll build command seems to work fine, though:

           Writing: /srv/jekyll/_site/news-and-events/summer-dojo/index.html
                    done in 23.654 seconds.
 Auto-regeneration: disabled. Use --watch to enable.

Adding the gem "webrick" dependency to Gemfile solves the jekyll serve command issue.

I confirm it works now with docker.io/jekyll/jekyll:latest (aka "docker.io/jekyll/jekyll@sha256:d5ce76846e2c4e037040d093954aae4441eb45e2e2ae4ff84cd7aeca6e694b28"
)
