+Instead of build Zeppelin distribution package and docker image everytime during development,
+Zeppelin can run locally (such as inside your IDE in debug mode) and able to run Interpreter using [K8sStandardInterpreterLauncher](https://github.com/apache/zeppelin/blob/master/zeppelin-plugins/launcher/k8s-standard/src/main/java/org/apache/zeppelin/interpreter/launcher/K8sStandardInterpreterLauncher.java) by configuring following environment variables.
+
+| Environment variable | Value | Description |
+| ----- | ----- | ----- |
+| ZEPPELIN_RUN_MODE | k8s | Make Zeppelin run interpreter on Kubernetes |
+| ZEPPELIN_K8S_PORTFORWARD | true | Enable port forwarding from local Zeppelin instance to Interpreters running on Kubernetes |
+| ZEPPELIN_K8S_CONTAINER_IMAGE | <image>:<version> | Zeppelin interpreter docker image to use |
