Overview
CRI-O is an implementation of the Kubernetes CRI (Container Runtime Interface) designed to allow Kubernetes to use any OCI (Open Container Initiative) compatible runtime. It serves as a lightweight alternative to Docker, Moby, or rkt for running Kubernetes pods. CRI-O supports OCI container images and can pull images from any compliant container registry. It utilizes the containers/image library to pull images and the containers/storage library to manage layers and create root file-systems. Networking is configured through CNI, making it compatible with various CNI plugins. CRI-O is a community-driven, open-source project developed by contributors from companies like Red Hat, Intel, SUSE, and IBM. It is suitable for users who require a focused and efficient container runtime specifically for Kubernetes environments.
