The Kubernetes control plane can now be distributed across multiple nodes, bringing resiliency to the cluster while maintaining a low footprint using [Dqlite](https://dqlite.io/), the distributed SQL engine as the Kubernetes datastore. On Linux, you can download and test highly available MicroK8s from the ‘ha-preview’ branch: ``` sudo snap install microk8s --classic --channel=latest/edge/ha-preview ``` If you already have MicroK8s, learn how to upgrade to the ha-preview channel and set up your MicroK8s HA cluster in the [MicroK8s HA documentation](https://microk8s.io/docs/high-availability). If you want to test the HA feature on [Windows](https://microk8s.io/docs/install-alternatives#heading--windows) and [macOS](https://microk8s.io/docs/install-alternatives#heading--macos), follow the corresponding installation instructions and run the following command after the installation is complete: ``` multipass exec microk8s -- sudo snap refresh microk8s --classic --channel=latest/edge/ha-preview ``` Note that the ha-preview version comes with the high availability feature enabled by default. This means that adding at least two nodes to the cluster will automatically form a highly available control plane across the three nodes. Once you have added the additional nodes to the HA cluster, microk8s status output will look like this: We would love to hear your feedback on this new feature, so feel free to reach out to our team on [Discourse](https://discuss.kubernetes.io/c/general-discussions/microk8s), the [Kubernetes Slack](http://slack.kubernetes.io/) #microk8s channel or raise any bugs you might find on [MicroK8s GitHub](https://github.com/ubuntu/microk8s/issues/). ## Sign up for our newsletter Get the latest Canonical news and updates in your inbox.
