# Using Podman instead of Docker Podman has an [Docker API compatibility layer](https://podman.io/blogs/2020/06/29/podman-v2-announce.html#restful-api). k3d uses the Docker API and is compatible with Podman v4 and higher. !!! important "Podman support is experimental" k3d is not guaranteed to work with Podman. If you find a bug, do help by [filing an issue](https://github.com/rancher/k3d/issues/new?labels=bug&template=bug_report.md&title=%5BBUG%5D+Podman) ## Using Podman Ensure the Podman system socket is available: ```bash sudo systemctl enable --now podman.socket # or sudo podman system service --time=0 ``` To point k3d at the right Docker socket, create a symbolic link: ```bash ln -s /run/podman/podman.sock /var/run/docker.sock # or install your system podman-docker if available sudo k3d cluster create ``` Alternatively, set DOCKER_HOST when running k3d: ```bash export DOCKER_HOST=unix:///run/podman/podman.sock sudo --preserve-env=DOCKER_HOST k3d cluster create ``` ### Using rootless Podman Ensure the Podman user socket is available: ```bash systemctl --user enable --now podman.socket # or podman system service --time=0 ``` Set DOCKER_HOST when running k3d: ```bash XDG_RUNTIME_DIR=${XDG_RUNTIME_DIR:-/run/user/$(id -u)} export DOCKER_HOST=unix://$XDG_RUNTIME_DIR/podman/podman.sock k3d cluster create ``` ## Creating local registries Because Podman does not have a default "bridge" network, you have to specify a network using the `--default-network` flag when creating a local registry: ```bash k3d registry create --default-network podman mycluster-registry ``` To use this registry with a cluster, pass the `--registry-use` flag: ```bash k3d cluster create --registry-use mycluster-registry mycluster ``` !!! note "Incompatibility with `--registry-create`" Because `--registry-create` assumes the default network to be "bridge", avoid `--registry-create` when using Podman. Instead, always create a registry before creating a cluster.
