A lightweight alternative to KinD for local development. Read the introductory blog post. There is a more updated tool rancher/k3d which has more functionality than this tool and is written in go, I'd urge you to give it a try over this repo.

1. You need docker installed.

2. Just run:

   curl -sSL https://raw.githubusercontent.com/zeerorg/k3s-in-docker/master/install-script.sh | sudo bash -
   k3d create

3. If you have rust toolchain installed, you can install it using: cargo install k3d && k3d create

1. Supports arm64 and armhf
2. Fast boot time
3. Supports starting and stopping without losing previous state
4. Lightweight compared to KinD

Normal flow:

1. k3d create
2. export KUBECONFIG=$(k3d get-kubeconfig)
3. kubectl get pods --all-namespaces
4. If you want to delete the cluster do: k3d delete

If port 6443 is occupied you can specify a different port in first step: k3d create -p 10001. This will create a docker container named k3s_default with port 10001 exposed.

You can specify a different name for cluster with k3s create -n <name>, but then keep in mind to do k3d get-kubeconfig -n <name> when getting kubeconfig.

k3d 0.1.0

Run k3s in Docker
USAGE:
    k3d [SUBCOMMAND]
FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information
SUBCOMMANDS:
    check-tools       Check docker running
    create            Create a single node k3s server
    delete            Delete cluster
    get-kubeconfig    get kubeconfig.yaml location
    help              Prints this message or the help of the given subcommand(s)
    list              List all clusters
    start             Start a stopped cluster
    stop              Stop a cluster

1. One of the features I wanted to add is an insecure registry support. This can be done after k3s PR #248 is approved.
2. Upgrade this to version 0.2.x of k3s
