====== Docker - Networking - Change the default IP address ======

Change the default 172.17.0.0/16 network.

Add **DOCKER_OPTS="--bip=10.0.0.10/24"** to /etc/docker/docker.io and reboot.

<file bash /etc/default/docker>
DOCKER_OPTS="--bip=10.0.0.10/24"
</file>

Check the IP:

<code bash>
ip addr | grep docker
8: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default 
    inet 10.0.0.10/24 brd 10.0.0.0 scope global docker0
</code>

or

<code bash>
ifconfig docker0
docker0   Link encap:Ethernet  HWaddr 56:84:7a:fe:97:99  
          inet addr:10.0.0.10  Bcast:0.0.0.0  Mask:255.255.0.0
