The
hadolintwarning DL3009 is only relevant when optimizing a docker container's size. It's not needed for security or other reasons. Not only is this rule annoying; following the rule can also increase docker image build times. The benefit does not seem to outweight the drawbacks, so I added it to the list of ignored rules.Conversely, DL3047 (about the syntax of CMD statements) is probably better to keep, as a matter of modern practices surrounding Dockerfiles.
