# There are two types of releases managed by this script. If the git tag for the release
# is of the form `<semantic_version>`, then the release is a standard rucio release.
# If the git tag for the release is of the form `webui-<semantic_version>`, then the release is a WebUI release.
# Standard rucio releases are tagged with the rucio release version and DO NOT build the WebUI.
# WebUI releases are tagged with the WebUI release version and build the webui containers only.
#
# Below is the usage of the script to describe the tagging scheme used by the Docker Images
#
# Generates the image tags for the containers present in the containers repository
# The input is in CSV format:
# {sub_directory}, {parent_image}, {config_paramms}
# where,
# sub_directory: name of the sub_directory in rucio/containers reposistory that contains
# the Dockerfile. If the Dockerfile has a different name, then the full path to the Dockerfile must be specified.
# For example, fts-cron/Dockerfile_cpp is also a valid value.
# parent_image: OPTIONAL name of the parent image that is required to be available on Docker Hub before building this image.
# Parent images must begin with rucio- and can specify the #TAG placeholder to refer to the current tag being pushed.
# For example, rucio-clients:release-#TAG
# config_params: These are described in the CONFIG section and are used to generate
# the image tags that will be pushed to DockerHub for the given {sub_directory}
#
# CONFIG PARAMS
# -------------
# prepend-rucio: adds `rucio-` to image name
# prepend-release: adds `release-` to image name
# push-tagged: adds the $GIT_TAG to image name
# push-latest: if present, and the latest commit SHA on master branch
# matches the last commmit SHA of the current tag, adds release
# version to image name.
# force-latest: if present, the latest tag will be force pushed to Docker Hub
# latest-only: if present, only the latest tag will be pushed to Docker Hub
# custom-tag=value: If present, the value of the custom tag will be appended to the image tag.
# If push-latest is also present, then the custom tag will be appended to the latest tag as well.
# For example, custom-tag=java will append `java` to the image name.
#
# The following truth table is used to determine the Docker Hub tag
# The configuration parammeters are: preprend_release, push_tagged
# | prepend_release | push_tagged | image_tag |
# |----------------- |------------- |------------------- |
# | 0 | 0 | Check for latest tag|
# | 0 | 1 | :$GIT_TAG |
# | 1 | 0 | Config Error |
# | 1 | 1 | :release-$GIT_TAG |
