Rancher server restart loop

Rancher 2.x
1

I’m trying to evaluate Rancher 2.1.5 and I’ve hit a snag. I’m using ESXi 6.7 as a platform, and I’ve created a server running RancherOS. After that, I SSH in and run sudo docker run -d --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher:latest -v /opt/rancher:/var/lib/rancher

That appears to work okay, however, a docker ps shows this:

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
f7076c909706 rancher/rancher:latest "entrypoint.sh -v /o…" 35 seconds ago Restarting (0) 1 second ago awesome_wright

And looking at the logs for the container shows this:

rancher version v2.1.5
rancher version v2.1.5
rancher version v2.1.5
rancher version v2.1.5
rancher version v2.1.5
rancher version v2.1.5
rancher version v2.1.5
rancher version v2.1.5
rancher version v2.1.5
rancher version v2.1.5

Running without the -v argument works properly. How can I fix this and get the server to start properly while keeping the data persistent?

My guess is that /opt/rancher does not exist? You may need to manually create the rancher directory in opt

I am in the same case, started using:

sudo docker run -p 80:80 -p 443:443 rancher/rancher:latest -v /opt/rancher:/var/lib/rancher

I suspect my machine to be running already in a docker.
[edit] … after checking, it seems it is not the case. Any idea?

@Crackerjam did you find a solution?

I’m having the same problem. I have tried creating the “/opt/rancher” directory first, turning off SELinux, and changing the directory to 777. It made no difference, it still just goes into a restart loop.

Running without the volume works fine.

The command is as it is shown in the docs, the -v is a docker run parameter, not a Rancher parameter.

docker run -d --restart=unless-stopped \
  -p 80:80 -p 443:443 \
  -v /opt/rancher:/var/lib/rancher \
  rancher/rancher:latest

Thanks, that was my problem. I was just appending the -v parameter to the end.
