Missing bridge-utils dependency

[ruphin]

On a vanilla Ubuntu install with Docker 0.9, pipework produces the following error:

pipework: line 152: brctl: command not found

The brctl command is part of the bridge-utils package in Ubuntu, which was a dependency of LXC. With Docker 0.9 no longer depending on LXC, it is no longer installed. I recommend putting up a message in the Readme notifying Docker 0.9 users that Pipework requires bridge-utils.

Ah, wait, that shouldn't happen — pipework should be able to operate without brctl. It is supposed to degrade gracefully to ip link. I guess something is wrong here.

Thanks for reporting this!

I also get this error (but the line number is now 149). I tried executing the ip link command directly and it fails. I'm not sure what this means.

$ sudo ip link set br1 type bridge
Cannot find device "br1"

chatter, can you post the output of running your pipework command?

[chatterplug]

Here it is:

$ pipework br1 $(docker inspect --format='{{.ID}}' mongo) 192.168.1.1/16
/usr/bin/pipework: line 149: brctl: command not found

you need to have bridge-utils package installed

sudo apt-get update

sudo apt-get install bridge-utils

kikitux is correct, you are specifying a bridge interface that does not exist, pipework is trying to create it for you.
