Hello. I'm trying to run the rancher/rancher for educational purposes with no luck. I want to run it as a single container as said in the rancher doc so the same container makes of master and worker node, but I've had no luck. It stops at "provisioning cluster" and begin to restart the container over and over. So I wonder if someone has been successful on running this container.

I haven't activated notify me

Nobody has tried it?

I haven't been able to get it running. It's erroring out waiting for containerd startup. Combined with the poor community apps template and lack of support thread, I'm guessing someone just messed up the configuration of the docker with some sort of auto-generation and just never tested it.

Did you eventually get this going?

You can think of the Rancher docker container as a management console for creating Kubernetes clusters. It should be possible to manually provision a VM and have rancher use this VM to create a one node kubernetes cluster. If you want to go beyond one node, you'd be using at least 3 VMs + the rancher container.

 

What would be really cool is if someone could figure out a way to enable the Rancher container to automatically provision VMs to run as k8s nodes on Unraid.

Necroing this thread, but it's the top search recommendation from Google on this topic, just for anyone else who runs into the problem. 4 years later, this Docker container still does not work on Unraid. I have a separate cluster of RasPi's already made, and I'm just wanting to manage it from my Unraid host, which is a more powerful machine. When the container starts up, it's looking for a k3s configuration already built, but obviously, it's not going to have that because it's in a container on Unraid. There's no obvious way to configure this, as Docker is expecting a simple port and volume mapping. I don't think it's actually possible for this to work in Unraid. I believe you'd need to have k3s running in the Unraid host system, which is inadvisable (not even sure if possible, would be a lot of effort if it is).

The best workaround I can think of is to just create a VM and install Rancher the normal way. Good luck, I wish LimeTech would moderate these apps a little!
