CRI-O

Lightweight Container Runtime for Kubernetes

About CRI-O

CRI-O is an OCI-compatible container runtime designed specifically for Kubernetes. It provides a lightweight alternative to Docker, enabling Kubernetes to run any OCI-compliant container from any registry. CRI-O is optimized for stability, passing all Kubernetes tests, and supports runtimes like runc and Kata Containers. It integrates seamlessly with Kubernetes tools such as Minikube and kubeadm, and is pre-configured in Kubic. Developed by a community of contributors including Red Hat, Intel, and SUSE, CRI-O is a CNCF graduated project focused on performance, security, and compatibility.
