Lightning Talk: Extending Kubernetes with gRPC - Vladimir Vivien, VMware
summary
gRPC becomes the actual plugin channel for Kubernetes: the Container Storage Interface exposes storage ops as gRPC, letting vendors ship CSI driver runs in a pod that communicates with kubelet and external components via UNIX domain sockets for local RPC or TCP, replacing in-tree volume code. External attacher and provisioner processes talk over gRPC so drivers live outside the API server. Other subsystems (Device Plugin, KMS, CRI device management) adopt the gRPC-based plugin model and it is working in production.
