k3s on Gitpod

Just click on the button above and you will be in a Gitpod workspace with k3s running.

Based on fntlnz/gitpod-k3s, this version is using a pre-baked workspace image, which has QEMU installed and the VM's root filesystem image pre-created, resulting in much faster initial workspace initialization.

Note: I do not plan to keep this workspace image up-to-date with gitpod/workspace-full. You can build and push your own after checking this repository out:

$ docker build -f Dockerfile.k3s -t <your_registry>/gitpod-k3s-qemu:latest .

$ docker login <your_registry>
$ docker push -a <your_registry>/gitpod-k3s-qemu

You can copy the .gitpod.yml to your own project to have the k3s environment ready in there.

Here's a diagram of the interactions that also shows how the various components interact with each other.

Usage

At start, the workspace will start a VM in your gitpod workspace and automatically install K3S on it on the first workspace start-up. Your local environment will be auto-configured to access it with kubectl.

Connecting via kubectl

When you open your workspace terminal, kubectl is already configured to use the kubeconfig located at /workspace/.kubeconfig.

Connecting via K8S API

The Kubernetes API is reachable on localhost:6443.

Connecting via SSH

You can connect to the VM via ssh at any moment. The ssh daemon is exposed on 127.0.0.1 for the workspace on port 2222.

• username: root
• password: root

ssh -p 2222 root@127.0.0.1

You can use the /opt/qemu-k3s/{ssh.sh, scp.sh} scripts to run commands or copy files to/from the VM.
