+## Configuring Docker to use a proxy
+
+As of v1.0, minikube automatically configures the Docker instance inside of the VM to use the proxy environment variables, unless you have specified a `--docker-env` override. If you need to manually configure Docker for a set of proxies, use:
+
+
+```shell
+minikube start \
+  --docker-env=HTTP_PROXY=$HTTP_PROXY \
+  --docker-env HTTPS_PROXY=$HTTPS_PROXY \
+  --docker-env NO_PROXY=$NO_PROXY
