 Finally, create an alias for the Ark client's Docker executable. (Make sure that your `KUBECONFIG` environment variable is pointing at the proper config first). This will save a lot of future typing:
 
 ```
-alias ark='docker run --rm -v $(dirname $KUBECONFIG):/kubeconfig -e KUBECONFIG=/kubeconfig/$(basename $KUBECONFIG) gcr.io/heptio-images/ark:latest'
+alias ark='docker run --rm -u $(id -u) -v $(dirname $KUBECONFIG):/kubeconfig -e KUBECONFIG=/kubeconfig/$(basename $KUBECONFIG) gcr.io/heptio-images/ark:latest'
 ```
 *NOTE*: Depending on how your Kubeconfig is written--if it refers to the Kubernetes API server using the host machine's `localhost`, for instance--you may need to add an additional `--net="host"` flag to the `docker run` command.

 While it is possible to build and run the `ark` executable yourself, it is recommended to use the containerized version. Use the alias described in the quickstart:
 
 ```
-alias ark='docker run --rm -v $(dirname $KUBECONFIG):/kubeconfig -e KUBECONFIG=/kubeconfig/$(basename $KUBECONFIG) gcr.io/heptio-images/ark:latest'
+alias ark='docker run --rm -u $(id -u) -v $(dirname $KUBECONFIG):/kubeconfig -e KUBECONFIG=/kubeconfig/$(basename $KUBECONFIG) gcr.io/heptio-images/ark:latest'
 ```
 
 Assuming that your `KUBECONFIG` variable is set, this alias takes care of specifying the appropriate Kubernetes cluster credentials for you.
