Try to connect onos contrller in remote sever's container

[minziran]

I try to connect onos contrller in remote sever's container. But it shows Unable to contact the remote controller at 129.00.09.82:8190
The mininet command is sudo mn --topo=linear,3 --controller=remote,ip= 129.00.09.82:8190
The Ip I used is floating Ip
Then I use the command sudo ovs-vsctl set-controller s1 tcp:129.00.09.82:8190:6653 to set controller. It failed.

But if I run mininet on the same sever as docker container
I use the command sudo mn --topo=linear,3 --controller=remote,ip=127.0.0.1:8190
and set use this command sudo ovs-vsctl set-controller s1 tcp:172.17.0.2:6653
I succeed.
I know the success from karaf@root > when I type devices, it shows connected.
