Implement `docker-compose down [--volumes]` about sbt-docker-compose

[kurtkopchik]

The plugin was created before dockerComposeDown existed which is why I'm using dockerComposeStop instead. A lot of people are on older versions of Docker (especially build machines) so I would prefer to introduce dockerComposeDown in a minor version as you suggest and deprecate dockerComposeStop for eventual removal in a future major version release.

One thing I did like about dockerComposeStop is that you do have the ability to leave your containers behind which can be helpful when debugging an instance that fails to start.

As for the particular issue with named volumes it would also probably be pretty easy to add some code that gets the set of named volumes and explicitly removes them using docker volume rm <volumeName> command in the same fashion that I remove named networks during the execution of the dockerComposeStop.

Hi @ches, so that you are not affected by the current dockerComposeStop command leaving behind named volumes I made an update that attempts to remove them on shutdown in a similar fashion to how named networks are removed.

I haven't extensively tested it but released a 1.0.24-SNAPSHOT version for now. If it works for you I can look to get it included in the next official release.

resolvers += "Sonatype Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots/"
addSbtPlugin("com.tapad" % "sbt-docker-compose" % "1.0.24-SNAPSHOT")

Thanks a lot for doing this @kurtkopchik, I could have taken a stab at it but you beat me to it. Just getting back to it after a few days but I'm using the snapshot now and it's working well so far.

Hi @ches - Happy to help! This change is now included in an official release:

addSbtPlugin("com.tapad" % "sbt-docker-compose" % "1.0.24")
