Today, Kubernetes upstream made the 1.21 release candidate available for download and experimentation ahead of general availability, which will come later in April. 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.

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 or Slack (#microk8s). And if you have any bugs or technical issues to report, you can file them over on GitHub.

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/beta –classic

Alternatively, go to https://snapcraft.io/microk8s and select 1.21/beta

MicroK8s runs on Ubuntu and all major Linux distributions, and even natively on Windows and macOS. It is compatible with x86 and ARM architectures, so you can test it on your RaspberryPi 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, GitHub or Slack (#microk8s). We’d really appreciate it.

For more on MicroK8s you can read the docs, follow the tutorials or dive into the use cases.
