3 [containerd] An industry-standard container runtime with an emphasis on simplicity, robustness and portability
4 Kubespray supports basic functionality for using containerd as the default container runtime in a cluster.
6 _To use the containerd container runtime set the following variables:_
10 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.
13 container_manager: containerd
19 etcd_deployment_type: host
24 Example: define registry mirror for docker hub
27 containerd_registries:
29 - "https://mirror.gcr.io"
30 - "https://registry-1.docker.io"
33 `containerd_registries` is ignored for pulling images when `image_command_tool=nerdctl`
34 (the default for `container_manager=containerd`). Use `crictl` instead, it supports
35 `containerd_registries` but lacks proper multi-arch support (see
36 [#8375](https://github.com/kubernetes-sigs/kubespray/issues/8375)):
39 image_command_tool: crictl
