app-emulation/docker-compose: doesn't pull app-emulation/docker. Is it supposed behavior? Thanks!

Interesting question.  It's dependency dev-python/docker-py does not seem to depend on Docker either.  You could in theory set DOCKER_HOST to something that's not on your local machine.  If that was your case and we'd depend on docker as of today, someone else would open a ticket to get rid of that dependency maybe.

What do you think?

Thanks for reply!

I don't know Gentoo traditions so good.

Maybe, `remote` flag? Off by default, I think. IMHO your scenario is not default.

Cannot you even use a different engine like rkt?

[Comment 4 Alexander Kurakin 2020-04-12 07:35:09 UTC]

Not `remote` but `docker`, `rkt`, etc. flags, then?

I thought about it more and it's clear to me now that:

- Someone who aims at building docker images locally using docker-compose has a use case that dependencies on both docker and docker-compose and hence can be exacted to install both.

- The usual approach of printing helpful text about suggested packages in pkg_postinst does not seem needed because need of docker for local builds is obvious, in case of local builds.

- An use flag would not cause more trouble than good, e.g. needless rebuilds in case of change.

I would therefore like to close this ticket as "good enough as is".  Is that okay with you?

Yes, thanks.

Great, thanks for your understanding!
