OVERVIEW¶




WHAT IS K3D?¶

k3d is a lightweight wrapper to run k3s (Rancher Lab’s minimal Kubernetes
distribution) in docker.

k3d makes it very easy to create single- and multi-node k3s clusters in docker,
e.g. for local development on Kubernetes.

Note: k3d is a community-driven project but it’s not an official Rancher (SUSE)
product. Sponsoring: To spend any significant amount of time improving k3d, we
rely on sponsorships:

- GitHub Sponsors: - LiberaPay: - IssueHunt: https://issuehunt.io/r/k3d-io/k3d

LEARNING¶

k3d demo repository: iwilltry42/k3d-demo

Featured use-cases include:

 * hot-reloading of code when developing on k3d (Python Flask App)
 * build-deploy-test cycle using Tilt
 * full cluster lifecycle for simple and multi-server clusters
 * Proof of Concept of using k3d as a service in Drone CI

 * Rancher Meetup - May 2020 - Simplifying Your Cloud-Native Development
   Workflow With K3s, K3c and K3d (YouTube)


REQUIREMENTS¶

 * docker to be able to use k3d at all
   * Note: k3d v5.x.x requires at least Docker v20.10.5 (runc >= v1.0.0-rc93) to
     work properly (see #807)
 * kubectl to interact with the Kubernetes cluster


RELEASES¶

Platform Stage Version Release Date Downloads so far GitHub Releases stable
GitHub Releases latest Homebrew stable - - Chocolatey stable - -


INSTALLATION¶

You have several options there:


INSTALL SCRIPT¶

INSTALL CURRENT LATEST RELEASE¶

 * wget:
   
   wget -q -O - https://raw.githubusercontent.com/k3d-io/k3d/main/install.sh | bash
   

 * curl:
   
   curl -s https://raw.githubusercontent.com/k3d-io/k3d/main/install.sh | bash
   

INSTALL SPECIFIC RELEASE¶

Use the install script to grab a specific release (via TAG environment
variable):

 * wget:
   
   wget -q -O - https://raw.githubusercontent.com/k3d-io/k3d/main/install.sh | TAG=v5.0.0 bash
   

 * curl:
   
   curl -s https://raw.githubusercontent.com/k3d-io/k3d/main/install.sh | TAG=v5.0.0 bash
   


OTHER INSTALLERS¶

Other Installation Methods

 * :fontawesome-solid-beer: Homebrew (MacOS/Linux):
   
   brew install k3d
   
   
   
   
   Note: The formula can be found in homebrew/homebrew-core and is mirrored to
   homebrew/linuxbrew-core

 * AUR (Arch Linux User Repository):
   
   yay -S rancher-k3d-bin
   
   
   
   
   Package rancher-k3d-bin

 * Download GitHub Release
   
   Grab a release binary from the release tab and install it yourself

 * Chocolatey (Windows): choco install k3d
   
   Note: package source can be found in erwinkersten/chocolatey-packages

 * arkade: arkade get k3d

 * asdf: asdf plugin-add k3d && asdf install k3d latest
   
   Note: asdf plugin-add k3d, then asdf install k3d <tag> with <tag> = latest or
   5.x.x for a specific version (maintained by spencergilbert/asdf-k3d)

 * Others
   * install via go: go install github.com/k3d-io/k3d/v5@latest (Note: this will
     give you unreleased/bleeding-edge changes)


QUICK START¶

Create a cluster named mycluster with just a single server node:

k3d cluster create mycluster


Use the new cluster with kubectl, e.g.:

kubectl get nodes


Getting the cluster’s kubeconfig (included in k3d cluster create)

Get the new cluster’s connection details merged into your default kubeconfig
(usually specified using the KUBECONFIG environment variable or the default path
$HOME/.kube/config) and directly switch to the new context:

k3d kubeconfig merge mycluster --kubeconfig-switch-context
