A MariaDB docker image with the UCEAP Drupal Template development seed data baked-in.
This needs the TERMINUS_TOKEN secret to be set in order to download the database backup from Pantheon.
When working locally you can set the TERMINUS_TOKEN environment variable and pass it to the build process as a secret like so:
docker build -t myusername/devcontainer-db-template --secret id=TERMINUS_TOKEN .
