With the move from the common-place Docker-based executor for Kubernetes pods to the Container Runtime Interface (CRI), the definition of the contract between container runtime and Kubernetes pod has gotten much clearer in the past year. Given the CRI is somewhat new, in this talk we'll explore what the CRI is and how container runtimes implement the CRI API to offer container execution to Kubernetes.
In addition, we'll look at how the CNCF containerd 1.0 release and the associated containerd CRI project are building a stable and performant core container execution environment for Kubernetes. We'll demonstrate how to use these CNCF projects together and do a quick demo of Kubernetes 1.9 running with containerd 1.0.1.
