    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
