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.
  • Helm and other tools may not function as normal due to dependency on Docker.
  • scale.yml and upgrade-cluster.yml are not supported on clusters using CRI-O.

To use CRI-O instead of Docker, set the following variables:

all.yml

download_container: false
skip_downloads: false

k8s-cluster.yml

kubelet_deployment_type: host
container_manager: crio

etcd.yml

etcd_deployment_type: host
