 ## Known incompatibilty with Moby
 
-  GPU nodes are currently incompatible with the default Moby container runtime provided in the default `aks` image. Clusters containing GPU nodes will be set to use the `aks-docker-engine` distro by default which is functionally equivalent to `aks` with the exception of the docker distribution.
- For users unable to use the `aks` OS image (eg. Sovereign Clouds), a workaround is provided to install Docker Engine instead of Moby. To use it, simply enable Docker Engine in your apimodel as follows:
-
-  ```json
-{
-  "apiVersion": "vlabs",
-  "properties": {
-    "featureFlags": {
-      "dockerEngine": true
-    }
-  }
-}
- ```
