# Run the Docker tests for the SDP - updated to use podman

# Usage Examples from 'test' dir under workspace branch root:
#    sdp/test/run_docker_tests.sh
#    sdp/test/run_docker_tests.sh ubuntu20
#    sdp/test/run_docker_tests.sh rocky9
#    sdp/test/run_docker_tests.sh centos7 ubuntu22
#    sdp/test/run_docker_tests.sh all
#    sdp/test/run_docker_tests.sh ALL
#
# Goes together with run_docker_tests.sh
#
# 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/...
