single node rancher on docker installation problem - container is in looped restart

[fenem]

Tim,

the

docker run -d --restart=unless-stopped -p 9090:80 -p 9091:443 --privileged -v /opt/rancher:/var/lib/rancher --name=rancher_docker_server rancher/rancher:latest

command instances a container that is in a constant restart loop. there is some noise about this on the internet; but with no clear solution. any insights how to mitigate?

Kind Regards,

Michael Fene'
