Woohoo! We would love to get your feedback ahead of the general release and hear about any bugs or issues you find. Or, if you just want to give the bleeding edge of K8s features a try, get up and running with [MicroK8s](http://microk8s.io/). Test the release on your machine, play around with it, kick the tyres. Then, if you have feedback, good or bad, let us know on [Discourse](https://discuss.kubernetes.io/c/general-discussions/microk8s/26) or [Slack](http://slack.kubernetes.io/) (#microk8s). And if you have any bugs or technical issues to report, you can file them over on [GitHub](https://github.com/ubuntu/microk8s/issues). ## How to test the latest Kubernetes with MicroK8s  To get the latest Kubernetes on your machine, install MicroK8s and get a lightweight, zero-ops K8s cluster: sudo snap install microk8s –channel=1.21/candidate –classic Alternatively, go to and select 1.21/candidate MicroK8s in snapcraft.io MicroK8s runs on Ubuntu and all major Linux distributions, and even natively on [Windows](https://ubuntu.com/tutorials/install-microk8s-on-windows#1-overview) and [macOS](https://ubuntu.com/tutorials/install-microk8s-on-mac-os#1-overview). It is compatible with x86 and ARM architectures, so you can test it on your [RaspberryPi](https://ubuntu.com/tutorials/how-to-kubernetes-cluster-on-raspberry-pi?&_ga=2.226925593.569641029.1615897880-603441733.1611930154#1-overview) if you want. In fact, if you do do this, PLEASE let us know how it goes because that sounds awesome. Just to reiterate: once you’ve done some testing if you have feedback or run into issues, let us know over on [Discourse](https://discuss.kubernetes.io/c/general-discussions/microk8s/26), [GitHub](https://github.com/ubuntu/microk8s/issues) or [Slack](http://slack.kubernetes.io/) (#microk8s). We’d really appreciate it. For more on MicroK8s you can [read the docs](https://microk8s.io/docs), [follow the tutorials](https://microk8s.io/tutorials) or [dive into the use cases](https://ubuntu.com/blog/what-can-you-do-with-microk8s). ## Sign up for our newsletter Get the latest Canonical news and updates in your inbox.
