containerd

containerd An industry-standard container runtime with an emphasis on simplicity, robustness and portability Kubespray supports basic functionality for using containerd as the default container runtime in a cluster.

To use the containerd container runtime set the following variables:

k8s_cluster.yml

When kube_node contains etcd, you define your etcd cluster to be as well schedulable for Kubernetes workloads. Thus containerd and dockerd can not run at same time, must be set to bellow for running etcd cluster with only containerd.

container_manager: containerd

etcd.yml

etcd_deployment_type: host

Containerd config

Example: define registry mirror for docker hub

containerd_registries:
  "docker.io":
    - "https://mirror.gcr.io"
    - "https://registry-1.docker.io"
