Proposal: Possibility to exclude containers on remove

[avoinea]

Motivation for this proposal

• Possibility to bulk remove all container except some (e.g. data container).

Proposal

• Add --exclude option for rm command:

  $ docker-compose rm -v --exclude data

The command above should remove all containers, except data one.

In some ways this is related to #1294 in that it's a request to be able to execute some command on a subset of services.

As you probably already know, this is possible by listing the services to include, but there is no way to say "all but one" or, "all but some".

If we were to support that, I think we would want to support it in a way that works for all commands, without having to add a new flag to each.

I have been considering something like this:

docker-compose rm -v -data

The - prefix would mean to exclude it from the list of services. I'm not sure how that would work with the docopt argument parser though.

I believe this is similar enough to #1294, going to close

I am sad that this was closed. Issue #1294 mentions both up and down but only addresses up and ignores down, while this issue is specifically about down, but was closed due to the other issue that only ended up addressing up. So now there is no issue specific to down such as this.
