Can Kubernetes be nodeless, and is nodeless Kubernetes still really Kubernetes? That is the question the Google Kubernetes Engine team asked themselves before embarking on a project to create a new operating mode for their 6-year-old Kubernetes platform, GKE. Go behind the scenes of the creation of GKE Autopilot, a fully managed "nodeless" Kubernetes platform, and hear from one of the creators how it was built, and why various decision decisions were made. Topics covered will include the trade off between operational support, security and Kubernetes compatibility, and why it actually makes sense for nodes to retain their semantic meaning on a nodeless Kubernetes platform. The community has seen several approaches for offering serverless/nodeless Kubernetes to operators, including with technology like Virtual Kubelet. This presentation will break new ground, providing an alternative path to achieving the goals of serverless Kubernetes without removing node-level APIs like affinity.
