-
-To access the pods or services at `localhost`, you need to do these steps:
-
-1. Log in to the Gravitino playground Trino pod using the following command:
-
-```
-TRINO_POD=$(kubectl get pods --namespace gravitino-playground -l app=trino -o jsonpath="{.items[0].metadata.name}")
-kubectl exec $TRINO_POD -n gravitino-playground -it -- /bin/bash
-```
-2. Log in to the Gravitino playground Spark pod using the following command:
-
-```
-SPARK_POD=$(kubectl get pods --namespace gravitino-playground -l app=spark -o jsonpath="{.items[0].metadata.name}")
-kubectl exec $SPARK_POD -n gravitino-playground -it -- /bin/bash
-```
-
-3. Port-forward the Gravitino service to access it at `localhost:8090`.
-
-```
-kubectl port-forward svc/gravitino -n gravitino-playground 8090:8090      
-```
-
-4. Port-forward the Jupyter Notebook service to access it at `localhost:8888`.
-
-```
-kubectl port-forward svc/jupyternotebook -n gravitino-playground 8888:8888
