Hi,

I setup a testing machine with an dhcp ip. After a reboot the IP changed. I reached the web ui via the new IP, but can't interact with RancherOS / Docker anymore. Custom containers are "in Progress". Show container details state is "running" and action "Stopping" is pending.

It seems there isn't a connection to the RancherOS docker anymore.

The IP shouldn't change in production. So it won't be a problem... but is it a bug?

How could I reconnect the "Host" with the local RancherOS docker?

Regards

Also with static IP same problem. After reboot there is a duplicate host in Rancher.
Any fix / update in the near future?

Yes there is a fix in 0.3.2 that will hopefully be released Monday. Regarding changing IPs, after 0.3.2 is released what will happen is that after reboot Rancher will detect the changed IP and you should see that reflected in the UI. Unfortunately we do not dynamically update the networking rules when an IP changes so you may need to restart the network agent. There's a good chance you won't need to, but there is a race condition condition there.

We released v0.3.3 this morning and it contains the fix for duplicate hosts.

After upgrade to 0.3.3 agent is dying after 8-10 seconds. Also deleted server and agent, installed it again. Same problem. I have to do some more tests.
