Open vSwitch bridged interfaces are not deleted after container stop

[Dmitriusan]

Ubuntu 14.04, docker 1.6.1, ovs-vsctl (Open vSwitch) 2.0.2 Steps to reproduce:

• start container that is bridged to an existing OVS bridge:

# pipework ovs-int $(docker run -d -p 8080:8080 satnam6502/go-webserver-helloworld 
/gopath/src/github.com/satnam6502/go-webserver-helloworld/hello) dhcp 0a:d0:cc:e0:02:01

• identify container

# docker ps
CONTAINER ID        IMAGE                                       COMMAND                CREATED              STATUS              PORTS                    NAMES
084bd6d0b240        satnam6502/go-webserver-helloworld:latest   "/gopath/src/github.   About a minute ago   Up About a minute   0.0.0.0:8080->8080/tcp   insane_mccarthy   

• stop container:

# docker stop 084bd6d0b240

• interface that have been created for container is still up and bridged to OVS:

# ovs-vsctl show
    Bridge ovs-int
        Port "veth1pl6217"
            Interface "veth1pl6217"
        Port ovs-int
            Interface ovs-int
                type: internal

Expected result: Virtual interface should be unbridged & deleted after container stop as stated at documentation

Hi! Thanks for reporting this. Unfortunately, I don't have an OVS setup to reproduce this here :(

Could you also attach the output of docker inspect for this container?

I finally got to reproduce this!

It looks like it's a normal behavior of OVS; when a port is deleted, it remains in the database and it still shows up. It doesn't seem to be related to pipework. If someone has an idea about how to change this, let me know!

But meanwhile I'll close this issue.

Thank you!
