CRI-O CRI gRPC API is one of 6 APIs that [CRI-O](https://apis.io/providers/cri-o/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include CRI, gRPC, Kubelet, and Kubernetes. The published artifact set on APIs.io includes API documentation and a GitHub repository.

CRI-O implements the Kubernetes Container Runtime Interface (CRI) gRPC API that the kubelet uses to manage pod sandboxes, containers, image lifecycle, and runtime status. The CRI gRPC API is served over a Unix domain socket (default /var/run/crio/crio.sock) and includes services for RuntimeService and ImageService as defined by the upstream CRI protobuf specification.
