+
+Start the proxy:
+
+```sh
+kubectl proxy &
+```
+
+Then curl the API server:
+
+
+```sh
+curl http://localhost:8001
+```
+
+Create a token:
+
+```sh
+export TOKEN=$(kubectl create token default)
+
+kubectl create clusterrole api-access-root \
+  --verb=get --non-resource-url=/*
+
+kubectl create clusterrolebinding api-access-root \
+  --clusterrole api-access-root --serviceaccount=default:default
+
+```
+
+Retrieve the API Server endpoint:
+
+```sh
+export APISERVER=$(kubectl config view | grep https | \
+  cut -f 2- -d ":" | tr -d " ")
+```
+
+Confirm that the `APISERVER` variable stored the same IP as the Kubernetes control plane IP by issuing the following two commands and comparing their outputs:
+
+```sh
+echo $APISERVER
+
+https://192.168.99.100:8443
+
+kubectl cluster-info
+
+```
+
+We can also get the certs straight from the list in `~/.kube/config`.
