k3s in docker

k3s is the lightweight Kubernetes distribution by Rancher: rancher/k3s This repository is basically zeerorg/k3s-in-docker reimplemented in Golang... just because I didn't have time to learn Rust. Also I've added some functionality.

Requirements

  • docker

Install

Grab a release from the release tab.

or...

Build

  1. Clone this repo, e.g. via go get -u github.com/iwilltry42/k3d-go/releases
  2. Inside the repo run
    • make bootstrap to install build tools and then make build to build for your current system
    • go install to install it to your GOPATH
    • make build-cross to build for all systems

Usage

Check out what you can do via k3d help

Example Workflow: Create a new cluster and use it with kubectl

  1. k3d create to create a new single-node cluster (docker container)
  2. export KUBECONFIG=$(k3d get-kubeconfig) to make kubectl to use the kubeconfig for that cluster
  3. execute some commands like kubectl get pods --all-namespaces
  4. k3d delete to delete the default cluster
