Canonical introduces high-availability Micro-Kubernetes

Want an even better way to run small Kubernetes clusters on your developer workstations, IoT devices, or the edge? One way to quickly get up to speed on Kubernetes is with Canonical's  MicroK8s. Microk8s also includes Canonical open-source add-on services such as a container registry, storage pass-through, and native GPGPU enablement for hardware acceleration and machine learning workflows.Now, with HA, MicroK8s is ready to move from Internet of Things (IoT) implementations, testing out Kubernetes implementations on a workstation, or simply learning Kubernetes to bigger, better cloud jobs. With the new MicroK8s release, HA is enabled automatically once three or more nodes are clustered, and the data store migrates automatically between nodes to maintain a quorum in the event of a failure. Designed as a minimal conformant Kubernetes, MicroK8s installs, and clusters easily on Linux, macOS, or Windows.To work, a HA Kubernetes cluster needs three elements. If you want, you can also configure MicroK8s to use etcd, but Dqlite provides automatic, autonomous high availability.To get this to work, all you need is to have three or more nodes in your cluster. The automatic promotion of standby nodes into the voting cluster of Dqlite makes MicroK8s HA autonomous and ensures that quorum is maintained even if no administrative action is taken.MicroK8s automatically chooses the best nodes to provide the datastore. MicroK8s manages its own control plane, ensuring API services stay up and running.This is pretty darn neat, and it's remarkably smooth for such a small Kubernetes implementation. MicroK8s is very easy to set up and configure, extremely lightweight and it easily emulates our production environments for seamless migration and deployment of the pipelines."But Canonical points out MicroK8s is also useful in production. In short, the new microK8s may be just what your company needs for developing new apps and deploying them to IoT devices and the edge. 5G5G is no reason to buy the iPhone 12 - or any phoneEnterprise SoftwareLinux 5.9: Not a game-changer, but a good, solid Linux kernelCloudVote safely: How to find a trustworthy election ballot drop-off locationEnterprise SoftwareOpen Invention Network open-source, non-aggression patents now covers Android and exFAT.Please review our terms of service to complete your newsletter subscription.By registering, you agree to the Terms of Use and acknowledge the data practices outlined in the Privacy Policy.You will also receive a complimentary subscription to the ZDNet's Tech Update Today and ZDNet Announcement newsletters.
