Container Runtimes containerd is a lightweight and performant implementation to run containers. Arguably the most popular container runtime right now. It is used by all major cloud providers for the Kubernetes As A Service products. CRI-O was created by Red Hat and with a similar code base closely related to podman and buildah. Docker - The standard for a long time, but never really made for container orchestration. The usage of Docker as the runtime for Kubernetes has been deprecated and removed in Kubernetes 1.24.
