Which version of Docker? I need to find some time to look at this with 1.9.x now.

The default behavior is to log volumes that it finds, but it only deletes volumes that are NOT connected to a container.

If you have running containers, do an inspect and see if you find one of those volumes in use.

they're not, since we run lots of builds on those specific hosts, we have LOOOOTS of non-used volumes x)

(Off-topic: do you want me to push a scalable stack for gitlab on compose templates? 😄)

Which version of Docker? I need to find some time to look at this with 1.9.x now.

Docker 1.9.0, build 76d6bc9

On the off topic note, I'd love to see a scalable Gitlab template. How are you handling storage/etc? I'm not familiar with Gitlabs architecture at the moment. If you have something to look at, open a PR, we can work through it in the compose-templates repo or if you want to make it a full on catalog entry, that would be good too. We have someone working with us on Mongo DB, and it is one of our first PRs from outside. There is some back and forth that might be helpful outlining what we are looking for.

Related to this issue, in Docker 1.9 you can name volumes, which makes them a little less like orphans and more like pets. Thoughts on what the appropriate behavior is for handling them?

On another unrelated note, have you looked at cloudnautique/cowbell? It is a webhook listener to scale up services in a stack. I'm interested in thoughts/feedback.

How are you handling storage/etc?

btsync handles syncing between hosts and could interact between containers over volume or nfs sharing. For us is great since we just have to run another container on one of our physical hosts and it backups entire storage.

Will do that, but I would prefer a full catalog entry hehehe :)

Nice to hear! We will need that as well!

I know there were changes from 1.8 to 1.9 related to volumes but I'm not on that scope yet, we've been tooooo busy over here.

have you looked at cloudnautique/cowbell?

Saw it now, nice! I've been thinking on how rancher could scale without having human intervention, but it would give some work, things such as using lb and hosts metrics for scaling services, and the most complex, for having pluggable hosts (sort of EC2 auto scalling for those who aren't on AWS) which could be maintained by the system by using docker-machine for creating them or deleting them.

Just an update on this issue, it looks like in 1.9.1 it is actually deleting the volume folder, but docker volume ls still shows the docker volume ls command.

Will need to update the volume stuff to use top level volume command functionality.

Is that implementation hard? (didn't read your repo code yet)

I don't think so, will try and get to it this weekend.

That would be awesome @cloudnautique !

@fernandoneto this is the repo I was talking about, a few days ago, that does some cleanup on unused docker volumes. Do you mind to stay on charge of performing an one-shot upgrade in case @cloudnautique releases a new version?

@cusspvz ok. If @cloudnautique release a new version i make the upgrade.

@fernandoneto @cusspvz I built a v0.3.0 container, and put the fixes on master. (I haven't moved the latest docker tag yet) Would you mind helping to test it out? Perhaps deploy it to a few nodes to make sure it doesn't do anything crazy =D I'm going to roll it to our CI environment as well, but we are still on Docker 1.8.x.

@cloudnautique i will test and as soon as i have news i give you feedback, and thanks for your availability.

@cloudnautique I did some tests and it seems that everything is working properly. i've created and remove some stack's and all volumes associated were deleted.

this is a part of the logs

Cool, thanks!

Based on the logs, I don't think this container did any of the deleting. Looks like Rancher might have done it for you, or docker rm -v was used? In Rancher environments typically systems that run docker natively are the culprits when there are orphaned volumes.

No i didn't use docker rm -v.

OK, I'll move this version to latest, and close out this issue.

Thanks for the help testing.

Just to confirm everything is working perfect with last version of docker

Great! thanks for following up @fernandoneto

@cloudnautique Thank you!!1 :)
