Run Jekyll in Docker on Mac OSX

Reading time ~1 minute


Jekyll is based on ruby, so we build our image based on the ruby image.

FROM ruby

Some gems requires a Javascript runtime, so we need to install node and python-pygments is required for syntax highlighting.

RUN apt-get update
RUN apt-get install -y node python-pygments

The jekyll gem. Bundler is required if you have your own Gemfile in the folder.

RUN gem install jekyll bundler

Map a folder from host to /src in the container and expose 4000


Setup working dir.


Ideally, we should run bundle install first and then have the ENTRYPOINT to be ENTRYPOINT ["jekyll"]. I don’t know how to do it that way. (CMD?)

ENTRYPOINT bundle install && jekyll serve -H

Build the docker image

Change directory into where the Dockerfile is stored. Do not miss the “.” a the end.

docker build -t mrcoder/jekyll .

Clone theme

I use a theme forked from here. Simply clone it locally:

git clone

Run the Docker image

docker run --rm -v "$PWD:/src" -p 4000:4000 mrcoder/jekyll

If you are running it with boot2docker, you need to find out the ip of the docker host with boot2docker ip and open the site with http://ip-of-the-host:4000.
