Test goal: connect docker to a custom bridge instead of the default docker0 bridge.

Process:

Install bridge-utils

Apt-get install bridge-utils

Close the docker0 bridge

Ifconfig docker0 down

Customize a bridge:

Brctl addbr bridge0ifconfig bridge0 192.168.227.1 netmask 255.255.255.0

Edit the / etc/defautl/docker file and append the following to specify the bridge to use:

DOCKER_OPTS= "- b=bridge0"

Start docker again:

Service docker start

Check to see if the bridge is working:

As you can see, the new bridge0 has been successfully created.
