# 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
```yaml
container_manager: containerd
```
## etcd.yml
```yaml
etcd_deployment_type: host
```
## Containerd config
Example: define registry mirror for docker hub
```yaml
containerd_registries:
"docker.io":
- "https://mirror.gcr.io"
- "https://registry-1.docker.io"
```
