When I input: `docker run -e CATTLE_AGENT_IP="121.xx.xx.4" -it --privileged -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/rancher:/var/lib/rancher rancher/agent:v1.0.2 http://121.xx.xx.4:8080/v1/scripts/874F461593B82EEEEB61:1468335600000:0SsoizxYtibU55WpXq7zcSR5gPg` the agent container started and then exited immediately, no host is added to server. no output can be found when I `docker logs agentcontainerid` My host is a centos 6.5 VM, with upgraded kernel to 3.10.xx. How can I do some troubleshooting? ---

The command given is supposed to run, create two other containers (named `rancher-agent-state` and `rancher-agent`) and then exit. Are the other two there? What’s in the logs for `rancher-agent`? ---

It looks like the rancher-agent-state was never run. There’s actually 3 containers that run. Can you look at the detailed agent logs?

But I can not find rancher directory in /var/log, so no any rancher agent log can be found. ---

The logs are in the container that exited. Use the `cp` command to copy the logs outside. `docker cp :/var/log/rancher /local/path` ---

Nope, I was wrong. It seems that the container that never ran creates the logs you’re looking for. What does `docker logs gigantic_lamarr` say? ---

nothing either. I decide to reset the host OS, it may be a problem related to the host system chaos. Thanks all!
