Rancher Container Keep Crashing with "Restarting (1)" Error

Rancher one line start up script usually some with this format

docker run -d -v /data/docker/rancher-server/var/lib/rancher/:/var/lib/rancher/ --restart=unless-stopped --name rancher-server -p 80:80 -p 443:443 rancher/rancher:stable

 It crashed all the time and working fine if we don't map the volume (docker -v)

Checking the docker log

/var/lib/docker/containers/<container_id>/<container_id>-json.log

 

Fixed it by adding the --privileged attribute

docker run --privileged -d -v /data/docker/rancher-server/var/lib/rancher/:/var/lib/rancher/ --restart=unless-stopped --name rancher-server -p 80:80 -p 443:443 rancher/rancher:stable
