docker-compose-theme-development.yaml

---

# An experimental docker-compose file to simplify theme development.
# Use this to deploy a database and the keycloak image: -
#
#   docker compose -f docker-compose-theme-development.yaml build
#   docker compose -f docker-compose-theme-development.yaml up -d
#
# 'keycloak.local' is the hostname used by the keycloak image
# so make sure your '/etc/hosts' file has an entry to allow routing
# to your local docker engine, typically: -
#
#   127.0.0.1 keycloak.local
#
# You can then navigate to keycloak at http://keycloak.local:8080
# where you should be able to login as 'admin' with the password 'blob111'.
#
# The project 'themes' directory is mounted into the container
# at '/opt/keycloak/themes'. This allows you to develop themes
# and modify the theme from outside the container and see the
# result without having to rebuild the container.
#
# The database is mounted into the local directory './data'.
# To reset the database shutdown the service and remove the data directory: -
#
#   docker compose -f docker-compose-theme-development.yaml down
#   rm -rf data

  # Our keycloak container image expects a PostgreSQL database
  # with a database called 'keycloak' and a 'keycloak' user.
