What Would a Kubernetes 2.0 Look Like As we approach the 10 year anniversary of the 1.0 release of Kubernetes, let's take stock of the successes and failures of the project in the wild. Also what would be on a wish list for a Kubernetes 2.0 release.

Wrote up what I'd love for #kubernetes 2.0: https://matduggan.com/what-would-a-kubernetes-2-0-look-like/ #devops #programming
