MDF_MAKEDOCKFILE_VERSION = 1.0.2
MDF_MAKEDOCKFILE_REPOSITORY = https://github.com/Thomvaill/Makedockfile.git
# CONFIG
# The following environment variables MUST be set in Makedockfile.conf:
# - MDF_REPOSITORY : the Docker repository name, ie the image name
#
# The following environment variables SHOULD be set/overriden in Makedockfile.conf, Makedockfile.dist.conf or by an environment variable:
# - MDF_REGISTRY : the Docker registry hostname. Useful for private registries. Default: blank
# - MDF_NAMESPACE : the Docker namespace name: on Docker Hub it's your username. It can be anything on a private one, or blank. Default: blank
# - MDF_BRANCH_TAG : the identifier used to generate the "branch-tag". The result of `git branch` is the default value
# - MDF_VERSION_TAG : the identifier used to generate the "version-tag". Disabled by default
# - MDF_UTAG : a unique identifier used to tag the current image. Something containing the current commit hash is a good choice!
# Default value: MDF_VERSION_TAG-COMMIT_HASH if MDF_VERSION_TAG is defined,
# just COMMIT_HASH if not
# You can execute `make print-utag` to see the result
#
# - MDF_BUILD_PARAMS : additional parameters to pass to docker build. Some useful ones: --no-cache, --squash...
# - MDF_RUN_PARAMS : additional parameters to pass to docker run. Some useful ones: -p, -v...
# - MDF_RUN_CMD : to override the default image command
# - MDF_TEST_PARAMS : additional parameters to pass to docker run in test mode. Especially used for volumes, to bind-mount test results
