This problem can be solved by setting a different instanceName for the consumer instance.

Under HOST networking mode, all dockers managed by Rancher are with the same docker0 IP, which is 172.17.0.1. Thus, RemotingUtil.getLocalAddress() always returns "172.17.0.1" for those dockers, which leads to a collision between consumers with the same PID, if using default "IP@pid" clientId.
But it's recommended you bump up your client version to the lastest, because the instanceName change to a new one with nanoTime to prevent this collision:
` if (this.instanceName.equals("DEFAULT")) {
this.instanceName = UtilAll.getPid() + "#" + System.nanoTime();
}`
