CRI-O is a lightweight container runtime for Kubernetes. Kubespray supports basic functionality for using CRI-O as the default container runtime in a cluster.
- Kubernetes supports CRI-O on v1.11.1 or later.

download_container: false
skip_downloads: false
etcd_deployment_type: host
kubelet_deployment_type: host
container_manager: crio
