Docker Container Development

In order to improve the docker containers, you must clone the docker container repos and learn the "docker build" command.


  1. Visit https://github.com/terra-ops/docker-drupal. Click the "Fork" button to create your own copy of the repo.
  2. Clone your repo:

    git clone https://github.com/MY-USERNAME/docker-drupal
  3. Edit the Dockerfile as you see fit.

  4. To get the changes to be available in containers on your system, run the docker build command:
    cd docker-drupal
    docker build -t terra/drupal .

Docker will attempt to rebuild the container based on your Dockerfile. If something fails you will have to edit the Dockerfile and try again.

The -t option indicates the name. Use the name from the Docker hub. the . indicates the path to the Dockerfile you are going to build.

When you do this, all new containers built from the terra/drupal image on your system will use your newly built image.

If you need to get rid of your customer terra/drupal image and start over, use docker rmi terra/drupal to get rid of it.

A fresh terra/drupal will download next time you enable your environment.

  1. Destroy any running containers you have for that image:

    docker kill myappenvironment_app_1
  2. Re-enable your environment and it will use the new terra/drupal image:

    terra environment:enable myapp environment
