# Builds and runs a container
#
# For consistent testing environment, it's the best to build the image locally and push it to
# the Docker hub repository. There exists one repository on Dockerhub: apachearchiva.
# The login data for the Dockerhub ID has to be given by the environment variable: DOCKER_HUB_PW
#
# The script first checks, if a image with the given CONTAINER_VERSION exists. If not, it tries to
# pull the image from Docker hub. If the pull fails, it tries to build a local one.
#
# If you have changes on the image, you should change CONTAINER_VERSION in this file, create it locally
# and push it to the Dockerhub repository: apachearchiva/build-webtest:${CONTAINER_VERSION}
# After that, push the changes to the git repository.
#
# The script tries to cleanup orphaned images from the local docker repository, if the CONTAINER_VERSION
# has changed.
#
# Always change the version, if your Dockerfile or scripts of the container change
