OCI, CRI, ??: Making Sense of the Container Runtime Landscape in Kubernetes - Phil Estes, IBM

on YouTube ↗23m

" summary

OCI forms the interoperability layer born in 2015 with the runtime spec and runc implementation (2017), and Kubernetes uses the CRI abstraction so any CRI-compliant runtime can plug in. Major implementations include containerd 18% adoption and cri-o 4% in surveys, containerd is now default in some managed services and Fargate, OpenShift defaults to cri-o, sandboxes like gVisor/Kata/Firecracker are usable via runtimeClass, and operators use crictl talking to the CRI socket for runtime-agnostic ops.
