re-use more layers #4

Open BlinkyStitt opened 6 years ago

BlinkyStitt commented 6 years ago

Move ENTRYPOINT and CMD earlier in the Dockerfile so layers are reused more often.

Also use --no-cache flag instead of manually deleting /var/cache/apk

I'm fine with the --no-cache change, but how does the other change result in layers being reused? I think that would only be the case if you had another image with an ENTRYPOINT named /entrypoint.sh and a CMD of ["curl"], right?

Right now it doesn’t change much. But if you add a version pin to curl and the latest alpine image hasn’t changed, everything up through CMD will be reused.
