# The base image runs certbot itself (ENTRYPOINT ["certbot"]). Reset it, or the
# CMD below is appended as arguments to certbot instead of replacing it. Both
# directives are in exec form: a shell-form ENTRYPOINT makes docker drop CMD
# altogether, and a shell-form CMD would expand into a nested /bin/sh -c.
# Keeping the loop in CMD is what lets a one-off run replace it outright:
#   docker run --rm -v letsencrypt:/etc/letsencrypt <image> certbot certificates
