What k3d is
k3d is a lightweight wrapper for running k3s, Rancher Lab’s minimal Kubernetes distribution, in Docker. It creates single-node and multi-node clusters, including for local Kubernetes development. The overview also lists development and CI uses such as code hot-reloading, a build-deploy-test cycle using Tilt, and running k3d as a service in Drone CI.
Docker is required, and kubectl is used to interact with the cluster. For k3d v5.x.x, the overview specifies Docker v20.10.5 or later and runc v1.0.0-rc93 or later. k3d is community-driven and is not an official Rancher (SUSE) product; its Free plan costs nothing, with sponsorships supporting development. It runs on Linux, macOS, and Windows, including self-hosted setups. Cluster configuration can include registry authentication and certificates, and the documentation describes local registries managed by k3d. Services can be exposed through Ingress or NodePort by mapping container ports to the host. Installation options include GitHub release binaries, Homebrew, AUR, Chocolatey, Scoop, arkade, asdf, and Go.
Who it suits

Getting started
- Choose an installation route such as a GitHub release binary, Homebrew, AUR, Chocolatey, Scoop, arkade, asdf, or Go.
- Make sure Docker is available; k3d v5.x.x lists Docker v20.10.5 and runc v1.0.0-rc93 as minimum versions for proper operation.
- Create a single-node or multi-node k3s cluster with k3d.
- Use kubectl to interact with the cluster.
- Configure registries.yaml if the cluster needs registry settings, authentication, or certificates.
Verdict
k3d provides a free, community-driven way to run k3s clusters in Docker, with local development and CI uses listed. Check its Docker and runc requirements before choosing it.
