A Docker container that listens for HTTP posts and generates a Jekyll website in an automated manner. With this container you could self-host a Jekyll website and add support to auto-deploy it when a push is made on Github or Bitbucket.
docker build -t mikroways/jekyll .
To run the container just execute the following command (in this example, it will clone and serve Mikroways' website).
docker run -p 8080:80 -d -e "HTTP_USER=mikroways" -e "HTTP_PASS=password" -e
"REPO_URL=https://github.com/Mikroways/mikroways.net.git" mikroways/jekyll
After starting, the container will deploy the website for the first time and set up basic authentication for automated deployments.
As you can see, you need to define three environment variables (which are required):
- HTTP_USER: username for HTTP authentication.
- HTTP_PASS: password for HTTP authentication.
- REPO_URL: git repository URL to clone from.
Automated deployment works executing the following actions:
- The repository will be cloned (or updated) in /tmp directory.
- bundle install and bundle exec jekyll build commands will be executed.
- The resulting HTML generated files in _site directory will be moved to /data directory, replacing existing files.
The first time the deployment is run can take some time (depending on repository size, internet connection, etc.). Following deployments should be much quicker, as it will just download changes and install only new gems.
Note that /data directory can be mounted from a volume, but that is not a requirement.
To use automated deploy you can choose between a simple method with basic HTTP authentication and a more complex one which uses both basic HTTP authentication and a secret in the requirement's body.
By default, the container supports basic authentication, using the username and password defined with the environment variables HTTP_USER and HTTP_PASS, so no further action is needed to use this method.
To see how to force the deployment, please refer to the Test section of this README.
This requires defining two additional environment variables:
- USE_SECRET: this variable must be set to 'yes' (lowercase).
- SECRET (optional): the secret you want to use.
In case you do not specify a secret, it will be automatically generated. In that case, you'll need to check the container logs and look for the string "Secret to send posts with" to get the secret:
Secret to send posts with:
5se7xfS2waUwwD9Nw4c0k4tvIuqGHUTDuALkeOk8W1Tflxn8xIJcA-O0Ay3S366Z
To test everything works OK follow the steps below.
- Access the website: after the first deploy has finished you should see the website online.
- Force deployment:
If you chose to use just basic authentication:
curl -X POST http://mikroways:password@hostname/deploy-with-basic-auth
If you chose to also use a secret:
curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d
'secret=5se7xfS2waUwwD9Nw4c0k4tvIuqGHUTDuALkeOk8W1Tflxn8xIJcA-O0Ay3S366Z'
http://mikroways:password@hostname/deploy-with-secret
If it worked OK you will see in the container logs that the deployment process has started. If anything was changed in the remote repository, you will see changes applied after deployment finishes.
Github only works with the basic authentication method. To set it up you need to go to Settings -> Webhooks & services -> Create webhook.
- Payload URL: http://HTTP_USER:HTTP_PASS@hostname/deploy-with-basic-auth
- Content type: any.
- Secret: leave it empty.
- Events: Push
