## Urgent Upgrade Notes 

### (No, really, you MUST read this before you upgrade)

After its deprecation in v1.20, the dockershim component has been removed from the kubelet.
From v1.24 onwards, you will need to either use one of the other [supported runtimes](https://kubernetes.io/docs/setup/production-environment/container-runtimes/) (such as containerd or CRI-O)
or use cri-dockerd if you are relying on Docker Engine as your container runtime.
For more information about ensuring your cluster is ready for this removal, please
