cmrn/jekyll-webhook

cmrn/jekyll-webhook is a docker image which:

  1. Builds a Jekyll site from source
  2. Runs an Nginx server to host the website
  3. Creates a GitHub webhook to pull in any new changes to the site

Basic Usage

Step 1 - Docker

To start cmrn/jekyll-webhook on port 80:

docker run -d -p 80:80 \ 
           -e REPO="https://github.com/cmrn/cameronmoon.com.git" \ 
           -e WEBHOOK_SECRET="change me" \ 
           cmrn/jekyll-webhook

Set WEBHOOK_SECRET to variable to a long, random passphrase, and set REPO to the clone URL of your GitHub repository.

Step 2 - GitHub

To set up the webhook in GitHub, go to your repository page, then go to Settings > Webhooks & Services > Add webhook. Set "Payload URL" to your server's address, followed by /webhook - for example, http://cameronmoon.com/webhook. Set "Secret" to the same value as WEBHOOK_SECRET. "Content type" should be "application/json", and the Webhook should only recieve the "push" event.

Configuration

The image can be given the following configuration values as environment variables:

  • REPO: Required. The clone URL for your Jekyll repository. If your repository is private, this should also contain a username and password.
  • WEBHOOK_SECRET: Required. The secret which authenticates genuine requests to the webhook. This should be a long, random secret shared only with GitHub.
  • WEBHOOK_ENDPOINT: Optional, defaults to /webhook. The endpoint for the webhook. Change this if you want to publish something at the URL /webhook.
  • BRANCH: Optional, defaults to master. The branch to use from your repository. Another popular value is gh-pages, used by GitHub Pages.

Advanced Configuration

It's also possible to customise the nginx server configuration by linking in a new site.conf template. Save site.conf to your host machine, make your changes, and link it into your container:

docker run -d -p 80:80 \
           -v /path/to/your/site.conf:/site.conf \ 
           -e REPO="https://github.com/cmrn/cameronmoon.com.git" \ 
           -e WEBHOOK_SECRET="change me" \ 
           cmrn/jekyll-webhook
