# Build a docker container and optionally execute command within a it
#
# Usage: build.sh <CONTAINER_TYPE> [--tag <DOCKER_IMAGE_TAG>]
#                [--dockerfile <DOCKERFILE_PATH>] [-it]
#                [--env <ENVIRONMENT_VARIABLE>]
#                [--net=host] [--cache-from <IMAGE_NAME>] [--cache]
#                [--name CONTAINER_NAME] [--context-path <CONTEXT_PATH>]
#                [--spec DOCKER_IMAGE_SPEC]
#                [--platform <BUILD_PLATFORM>]
#                [<COMMAND>]
#
# CONTAINER_TYPE: Type of the docker container used the run the build,
#                 e.g. "ci_cpu", "ci_gpu"
#
# BUILD_PLATFORM: (Optional) Type of build platform used for the build,
#                 e.g. "arm", "cpu", "gpu". Defaults to "cpu".
#
# DOCKER_IMAGE_TAG: (Optional) Docker image tag to be built and used.
#                   Defaults to 'latest', as it is the default Docker tag.
#
# DOCKERFILE_PATH: (Optional) Path to the Dockerfile used for docker build.  If
#                  this optional value is not supplied (via the --dockerfile
#                  flag), will use Dockerfile.CONTAINER_TYPE in default
#
# DOCKER_IMAGE_SPEC: Override the default logic to determine the image name and
#                    tag
#
# ENVIRONMENT_VARIABLE: Pass any environment variables through to the container.
#
# IMAGE_NAME: An image to be as a source for cached layers when building the
#             Docker image requested.
#
# CONTAINER_NAME: The name of the docker container, and the hostname that will
#                 appear inside the container.
#
# CONTEXT_PATH: Path to be used for relative path resolution when building
#               the Docker images.
#
# COMMAND (optional): Command to be executed in the docker container
