### Example

To install Kafka-UI need to execute follow:

```bash
helm repo add kafka-ui https://provectus.github.io/kafka-ui
helm install kafka-ui kafka-ui/kafka-ui --set envs.config.KAFKA_CLUSTERS_0_NAME=local --set envs.config.KAFKA_CLUSTERS_0_BOOTSTRAPSERVERS=kafka:9092
```

To connect to Kafka-UI web application need to execute:

```bash
kubectl port-forward svc/kafka-ui 8080:80
```

Open the `http://127.0.0.1:8080` on the browser to access Kafka-UI.
