CRI-O

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.
• etcd: configure either kubeadm managed etcd or host deployment

To use the CRI-O container runtime set the following variables:

all/all.yml

download_container: false
skip_downloads: false
etcd_kubeadm_enabled: true

k8s-cluster/k8s-cluster.yml

container_manager: crio

etcd.yml

etcd_deployment_type: host # optionally and mutually exclusive with etcd_kubeadm_enabled

all/crio.yml
