HEALTHCHECK CMD [ "docker-healthcheck" ]

# TODO:  Set healthcheck intervals...
#        https://docs.docker.com/engine/reference/builder/#healthcheck
#        The options that can appear before CMD are:
#
#        --interval=DURATION (default: 30s)
#        --timeout=DURATION (default: 30s)
#        --start-period=DURATION (default: 0s)
#        --retries=N (default: 3)

# TODO:  figure out how to slim down the size of the image. We can't
#        delete the pgtap/ repo because then we can't run makeinstall
#        when the container inits.
#        rm -r /pgtap only seems to save 20 mb
