# verify_docker invokes the given Docker image with the argument `version` and inspects its output.
# If its output doesn't match the version given, the script will exit 1 and report why it failed.
# This is meant to be run as part of the build workflow to verify the built image meets some basic
# criteria for validity.
#
# Because this is meant to be run as the `smoke_test` for the docker-build workflow, the script expects
# the image name parameter to be provided by the `IMAGE_NAME` environment variable, rather than a
# positional argument.
