Kubernetes 1.20: The Raddest Release
#kubernetes, #release

We’re pleased to announce the release of Kubernetes 1.20, our third and final release of 2020! This release consists of 42 enhancements: 11 enhancements have graduated to stable, 15 enhancements are moving to beta, and 16 enhancements are entering alpha.

A new Kubernetes release is always exciting, this one as well is. Another article talking about the news: Kubernetes 1.20 - What’s New?

My favorites:

  • Kubectl Debug Graduates to Beta. OpenShift had this since a long time as oc debug, it's good to finally see this coming to kubectl.
  • Alpha with updates: IPV4/IPV6. I'm still waiting to be finally able to have proper multi-stack support, this one brings us closer.

CentOS Project shifts focus to CentOS Stream
#centos

The future of the CentOS Project is CentOS Stream, and over the next year we’ll be shifting focus from CentOS Linux, the rebuild of Red Hat Enterprise Linux (RHEL), to CentOS Stream, which tracks just ahead of a current RHEL release. CentOS Linux 8, as a rebuild of RHEL 8, will end at the end of 2021. CentOS Stream continues after that date, serving as the upstream (development) branch of Red Hat Enterprise Linux.

This news flooded my news stream this week. Some other articles talking about this subject:

When I first read about this news I was puzzled and didn't understand the exact change. But now I get it and I'm more and more OK with the change. When I read the article from Kristian Köhntopp it all made sense. Todays world (at least in the area I'm working in) containers are the main way to package, distribute and run applications. The underlying OS just needs to make sure that containers and the Kubelet can run and provide a Linux Kernel, that's all. That's why I really like e.g. k3OS. And because of this I do not think that this move from the CentOS project is of any big issue. Of course there are use cases for a big-fat OS, it's just not something I use anymore.

How open is too open?
#opensource

When I look at open source projects, I divide the people involved into three categories: the investors, the contributors, and the users. The contributors do the work on the project, while the investors (if any) support the contributors in some way. The users are those who simply use the project without contributing to it.
