# We need to use the exec form to avoid running our command in a subshell and omitting signals,
# thus being unable to shut down gracefully:
# https://docs.docker.com/engine/reference/builder/#entrypoint
#
# Also we need to use relative path, because the exec form does not invoke a command shell,
# thus normal shell processing does not happen:
