Can not get -bip to work

[Lars-Erik Helander]

I am trying to assign a specific ip network to be used for containers using
the -bip option when starting the docker daemon.
The docker program (version 0.7.3) do not assign containers with ipadresses
from the network specified via the bip command.
Could anyone provide a working example where the bip option is used?

Hi,

What's the exact command-line that you're using, what does your network
setup look like, and what's the exact command that you use to start your
test container?

Thank you!

I have tried various ways to start the docker daemon:

docker -d -bip=192.168.55.0/24
docker -d -bip=192.168.55.0
docker -d -bip="192.168.55.0/24"
docker -d -bip="192.168.55.0"

My host has one physical ethernet port, assigned to 192.168.1.98. There are a number of other (non-docker) host on the 192.168.1.0 network.

My test container is started using

docker run -t -i busybox /bin/sh

Hi,

Sorry for the late answer, but then again, someone might hit this problem
as well...
If the docker0 bridge already exists, the -bip option has no effect.
Try to:
- shutdown Docker
- destroy docker0 ("ip link del docker0")
- restart Docker ("docker -d -bip=192.168.55.1/24")

Note that you should specify a netmask, and you shouldn't specify the
network address.

HTH,
