## What it is
cri-dockerd is an adapter that exposes the Docker Engine as a Kubernetes-compliant Container Runtime Interface (CRI), replacing the removed built-in dockershim. It is maintained by Mirantis and Docker so Kubernetes clusters can keep using Docker Engine as their container runtime.

## Use cases
- run kubernetes with docker engine after dockershim removal
- upgrade kubernetes cluster to 1.24+ while keeping docker runtime
- make docker engine cri compliant
- configure kubelet to use docker as container runtime
- use docker desktop as kubernetes container runtime

## When to choose
- you rely on Docker Engine tooling or Mirantis Container Runtime and need a Kubernetes-conformant runtime
- you are migrating clusters off the removed in-tree dockershim
- you use Docker Desktop's Kubernetes integration

## When to avoid
- you are starting a new cluster with no Docker dependency - containerd or CRI-O are simpler and more direct
- you need the highest performance runtime without an extra shim layer
- you require kubenet networking, which was removed alongside dockershim
