Jekyll environment for Docker

Extremely helpful Jekyll build and serve environment using Docker.

Environment Variables

• TARGET_REPO - Selects the repository that should be cloned when nothing is bind mounted.
• TARGET_BRANCH - Selects the branch on the selected repository to be cloned. Defaults to the master branch.
• JEKYLL_GITHUB_TOKEN - Sets the token used by the Jekyll GitHub API to get account information. It's only needed for local development, and shouldn't be committed into the repository.

Dockerfile

Here is an example of a Dockerfile that would set the environment variables you need. This version will allow for you to have your Jekyll site cloned and installed at build time, instead of startup time. This would be idea for more of a production type of environment.

FROM raveious/jekyll-website

# Sets the target repository
ENV TARGET_REPO=https://github.com/raveious/raveious.github.io.git \
    TARGET_BRANCH=master

Docker Container

Pull a ready to use Docker image from Docker Hub and run a Jekyll server locally which will also clone the master branch of this repository.

$ docker run -v $PWD:/site -e "TARGET_REPO=https://github.com/raveious/raveious.github.io.git" -p 80:4000 -it raveious/jekyll-website

Docker Compose

Here is an example of a Docker Compose file to start everything up correctly.

version: '2'

services:
  jekyll:
    image: raveious/jekyll-website
    volumes:
      - .:/site
    ports:
      - '80:4000'
    environment:
      - TARGET_REPO=https://github.com/raveious/raveious.github.io.git
      - TARGET_BRANCH=master
    env_file:
      - ./.env

You might not need the env_file section if you don't want to load extra environment variables that way. You would only want to do that if you have stuff that is specific to your local development environment, like the JEKYLL_GITHUB_TOKEN variable.

Volume Locations

• /site - Directory where Jekyll will look for content.
