Libcompose 1.0.0 <-> Compose 1.6.0 features

[vdemeester]

I've tried to come up with a feature grid / missing feature recap' in order to know what to do to achieve a complete compatibility with docker-compose ; and thus making it easy to follow afterwards.

The goal of this issue is to keep track of what is done and what's not. As it might be a little big, we'll probably split this up into small issues for each missing part.

I've created a 1.0.0 milestone (with a cool name I think 😝) to start having some goals and helping us to focus. I also want to follow the releases of the other docker projects (but that's another story).

Anyway, this is what I've got so far. Note there is some stuff that are present in libcompose but not in docker-compose.

ping @docker/libcompose-maintainers @ibuildthecloud @imikushin for feedback.
I probably missed some stuff so, let me know 😉.

Maybe

Those are in discussion / review on docker-compose so as long as they are not merged or completely sure to get in 1.6.0, it probably shouldn't be in 1.0.0 of libcompose. I'll create issues to track them down.

@vdemeester Wow, thanks, this is really helpful. I'll look over it more next year (next week 😄 )

[vdemeester]

I still have to list some stuff that would be in the 1.6.0 milestone for docker-compose, see https://github.com/docker/compose/milestones/1.6.0.

And there is also the test-acceptance tests, imported from docker-compose that should help 😉.

The --x-networking flag is now removed. Networks are now automatically created by default: https://docs.docker.com/compose/networking/

[vdemeester]

@F21 Thanks :-) I need to close this issue and split it up to be able to follow the gap and progress better ;-)
