Hi, I’m new to Kubernetes and Rancher. When I want to set up a local development/learning environment, I failed to make Rancher run in single-node mode using docker. After some painful testing, I figured out it might be related to openSUSE Tumbleweed. I create 3 identical VMs, each having 4 cores, 8GB of RAM, 120GB of storage, 2 NICs (one for VMnet8, DHCP, for accessing the internet; one for VMNet2, static configured, for internal communication). I installed Ubuntu 20.04LTS, openSUSE Tumbleweed, openSUSE 15.3, performed upgrade (apt update && apt full-upgrade -y, zypper dup -y, zypper up -y), and installed docker. The docker on ubuntu is installed by following official documents, the docker on openSUSE is installed by following the wiki ([Docker - openSUSE Wiki](https://en.opensuse.org/Docker)). All dockers can run the hello-world with the non-root account. Then I deployed the Rancher using command: docker run -d --restart=unless-stopped -p 80:80 -p 443:443 --privileged rancher/rancher:latest The result is: Ubuntu 20.03LTS and openSUSE Leap 15.3 have no issues, but the container on Tumbleweed keeps exiting and restarting. It starts, and waiting for server on 127.0.0.1:6443, and then failed with a FATAL, sometimes it’s k3s exit with code 1, sometimes it’s just a connection refused. And the web UI cannot be accessed. Here is the full log: (the log containing URLs to 127.0.0.1 and considered as a link, and new user can only have 2 links in the post, so I can’t post the log here) During the waiting process, I can see there is a k3s process using about 100%~200% CPU, but then exits and the container failed. To give more details about the system configurations, here is the kernel version and docker version: Ubuntu 20.04: Kernel 5.13.0-37-generic, Docker version 20.10.14, build a224086 openSUSE Tumbleweed: Kernel 5.16.15-1-default, Docker version 20.10.12-ce, build 459d0dfbbb51 openSUSE Leap 15.3: Kernel 5.3.18-150300.59.54-default, Docker version 20.10.12-ce, build 459d0dfbbb51 ---

It must be Tumbleweed related. Please take a look at the supported operating systems: [Support matrix | SUSE](https://www.suse.com/suse-rancher/support-matrix/all-supported-versions/rancher-v2-6-3/) ---

Oh, thanks! I noticed the rancher only supports openSUSE Leap 15.3, the Tumbleweed is not listed on the page.
