How can I specify a network to start rancher server in docker?

Archive Rancher 1.x

Hi, please help. I am trying to start rancher server with a docker network, such as macvlan, or bridge, but only got Restarting again and again.

Here is the input and message. What can I do if I want the rancher connect to physical network directly?

[root@rancher rancher]# docker network ls
NETWORK ID NAME DRIVER SCOPE
60de92b7020a bridge bridge local
9832507421bc host host local
c9024ce422e7 none null local

If you are trying to use docker network drivers for your container workloads, that’s not supported. Changing the settings or adding labels while launching rancher/server is of no use. BTW io.rancher.container.network=true is meant for workload containers not rancher server.
