My concerns echo Bob’s.
There is a ton to like about k3s. There is a super enthusiastic user community and it has pioneered bringing together an opinionated set of components with a streamlined experience. That is awesome!
- Is k3s a distribution? Many people publicly refer to it as such. The project page itself (k3s.io) has a headline saying “The certified Kubernetes distribution built for IoT & Edge computing”.
- Should the CNCF be a place to host distributions? (purpose discussion for the TOC)
- The name is very confusing. Kubernetes and k8s are synonymous. In fact, “k8s” is a registered trademark of the LF (https://www.linuxfoundation.org/trademark-list/). I’m not a lawyer, but these clearly commercially overlap and there is confusion in the marketplace. The LF may need to take action here regardless of the TOC decision.
- The places where k3s has made progress has, traditionally, included essentially forking parts of k8s and rebuilding. That forking has gotten thinner over time but is still there. There are promises around pushing changes upstream, but, to my knowledge, that has been minimal. The relationship there is fraught with a lot of history of friction and conflict.
- [point in time concern] The project is still pretty entangled with the rest of Rancher. This can be solved but obviously hasn’t been a priority. An example is that the documentation for k3s is part of the Rancher docs repo. Would the docs be included in the assets that come into the CNCF?
- The repo is also part of the Rancher org. The set of code owners is hidden and looks to be driven exclusively by Rancher (https://github.com/rancher/k3s/blob/master/CODEOWNERS).
There are a lot of thorny issues here. I have confidence in the TOC to be able to detangle these.
I’m deeply concerned about the idea that CNCF is accepting what appears to be a Kubernetes fork into sandbox.
The statements about “encouraging upstream” seem like good intentions only.
Kubernetes as a project has, in my opinion, succeeded in part because of the community dedication to staying upstream and not forking.
For clarity, I would be strongly in favor of k3s being part of Kubernetes upstream.
