# Build the Docker containers for the SDP - now using podman instead of docker

# Usage:
#   build_docker_image.sh [<OS>] [-clean]
# Usage Examples from 'test' dir under workspace branch root:
#    sdp/test/build_docker_image.sh
#    sdp/test/build_docker_image.sh ubuntu20
#    sdp/test/build_docker_image.sh centos7 ubuntu20
#    sdp/test/build_docker_image.sh all
#    sdp/test/build_docker_image.sh ALL -clean
#
# Goes together with run_docker_tests.sh
# This is provided as a useful tool for testing!
#
# Note that this file is expecting to be mapped into the root of the workspace
# and with the sdp directory in the same root.
# So workspace view should look something like:
#    View:
#        //guest/perforce_software/sdp/main/... //myws.sdp/sdp/...

# This file should be in <workspace-root>/sdp/test/
# We calculate dir relative to directory of script
ScriptDir="${0%/*}"
# shellcheck disable=SC2164
