Container-native workflow engine for Kubernetes
CRI-O
Lightweight container runtime made specifically for Kubernetes
About CRI-O
CRI-O is an open-source implementation of the Kubernetes Container Runtime Interface that lets the kubelet launch and manage OCI containers directly. It is deliberately minimal — it only does what the CRI requires, covering image management, container lifecycle, logging, monitoring and resource isolation — which makes it a lean, stable runtime for Kubernetes nodes.
