@ -35,14 +35,18 @@ Create a customized bridge on the Docker host
**Docker containers** connect to the Docker host network via a network bridge. To run xCAT in Docker, you should create a customized bridge according to the cluster network plan, instead of the default bridge "docker0".
As an example, create a bridge "br0" and attach the network interface "eth0" to it ::
Since the commands to create the bridge will break the network connection on "eth0", you'd better create a script such as "mkbridge" to create the bridge instead of running the commands sequencially. As an example, create a bridge "br0" and attach the network interface "eth0" to it. ::
[root@dockerhost1 ~]# cat /tmp/mkbridge
#!/bin/bash
brctl addbr br0
brctl setfd br0 0
ip addr del dev eth0 10.5.106.1/24
ip addr del dev eth0 10.5.106.5/24
brctl addif br0 eth0
ip link set br0 up
ip addr add dev br0 10.5.106.1/24
ip addr add dev br0 10.5.106.5/24
[root@dockerhost1 ~]# chmod +x /tmp/mkbridge
[root@dockerhost1 ~]# /tmp/mkbridge
