CRI-O, an OCI-based implementation of Kubernetes Container Runtime Interface, used in SUSE and openSUSE projects. CRI-O is meant to provide an integration path between OCI conformant runtimes and the kubelet. Specifically, it implements the Kubelet Container Runtime Interface (CRI) using OCI conformant runtimes. In this session, we will explore the CRI-O arhitecture to undersand how it leverages OCI projects to work with kubelet via CRI.
