ZooKeeper can be accessed via port 2181 on the following DNS name from within your cluster:

    zookeeper.workspace.svc.cluster.local

To connect to your ZooKeeper server run the following commands:

    export POD_NAME=$(kubectl get pods --namespace workspace -l "app.kubernetes.io/name=zookeeper,app.kubernetes.io/instance=zookeeper,app.kubernetes.io/component=zookeeper" -o jsonpath="{.items[0].metadata.name}")
    kubectl exec -it $POD_NAME -- zkCli.sh

To connect to your ZooKeeper server from outside the cluster execute the following commands:

    export NODE_IP=$(kubectl get nodes --namespace workspace -o jsonpath="{.items[0].status.addresses[0].address}")
    export NODE_PORT=$(kubectl get --namespace workspace -o jsonpath="{.spec.ports[0].nodePort}" services zookeeper)
    zkCli.sh $NODE_IP:$NODE_PORT

Kafka can be accessed by consumers via port 9092 on the following DNS name from within your cluster:

    kafka.workspace.svc.cluster.local

Each Kafka broker can be accessed by producers via port 9092 on the following DNS name(s) from within your cluster:

    kafka-broker-0.kafka-broker-headless.workspace.svc.cluster.local:9092
    kafka-broker-1.kafka-broker-headless.workspace.svc.cluster.local:9092
    kafka-broker-2.kafka-broker-headless.workspace.svc.cluster.local:9092

The CLIENT listener for Kafka client connections from within your cluster have been configured with the following security settings:
    - SASL authentication

To connect a client to your Kafka, you need to create the 'client.properties' configuration files with the content below:

security.protocol=SASL_PLAINTEXT
sasl.mechanism=SCRAM-SHA-256
sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required \
    username="user1" \
    password="$(kubectl get secret kafka-user-passwords --namespace workspace -o jsonpath='{.data.client-passwords}' | base64 -d | cut -d , -f 1)";

To create a pod that you can use as a Kafka client run the following commands:

    kubectl run kafka-client --restart='Never' --image docker.io/bitnami/kafka:3.6.1-debian-11-r0 --namespace workspace --command -- sleep infinity
    kubectl cp --namespace workspace /path/to/client.properties kafka-client:/tmp/client.properties
    kubectl exec --tty -i kafka-client --namespace workspace -- bash

    PRODUCER:
        kafka-console-producer.sh \
            --producer.config /tmp/client.properties \
            --broker-list kafka-broker-0.kafka-broker-headless.workspace.svc.cluster.local:9092,kafka-broker-1.kafka-broker-headless.workspace.svc.cluster.local:9092,kafka-broker-2.kafka-broker-headless.workspace.svc.cluster.local:9092 \
            --topic test

    CONSUMER:
        kafka-console-consumer.sh \
            --consumer.config /tmp/client.properties \
            --bootstrap-server kafka.workspace.svc.cluster.local:9092 \
            --topic test \
            --from-beginning
To connect to your Kafka nodes from outside the cluster, follow these instructions:
    NOTE: It may take a few minutes for the LoadBalancer IPs to be available.

        Watch the status with: 'kubectl get svc --namespace workspace -l "app.kubernetes.io/name=kafka,app.kubernetes.io/instance=kafka,app.kubernetes.io/component=kafka,pod" -w'

    Kafka Brokers domain: You will have a different external IP for each Kafka broker. You can get the list of external IPs using the command below:

        echo "$(kubectl get svc --namespace workspace -l "app.kubernetes.io/name=kafka,app.kubernetes.io/instance=kafka,app.kubernetes.io/component=kafka,pod" -o jsonpath='{.items[*].status.loadBalancer.ingress[0].ip}' | tr ' ' '\n')"

    Kafka Brokers port: 9094
To connect to your Kafka broker nodes from outside the cluster, follow these instructions:
    Kafka brokers domain: You can get the external node IP from the Kafka configuration file with the following commands (Check the EXTERNAL listener)

        1. Obtain the pod name:

        kubectl get pods --namespace workspace -l "app.kubernetes.io/name=kafka,app.kubernetes.io/instance=kafka,app.kubernetes.io/component=kafka"

        2. Obtain pod configuration:

        kubectl exec -it KAFKA_POD -- cat /opt/bitnami/kafka/config/server.properties | grep advertised.listeners
    Kafka brokers port: You will have a different node port for each Kafka broker. You can get the list of configured node ports using the command below:

        echo "$(kubectl get svc --namespace workspace -l "app.kubernetes.io/name=kafka,app.kubernetes.io/instance=kafka,app.kubernetes.io/component=kafka,pod" -o jsonpath='{.items[*].spec.ports[0].nodePort}' | tr ' ' '\n')"

The EXTERNAL listener for Kafka client connections from within your cluster have been configured with the following settings:
    - SASL authentication

To connect a client to your Kafka, you need to create the 'client.properties' configuration files with the content below:

security.protocol=SASL_PLAINTEXT
sasl.mechanism=SCRAM-SHA-256
sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required \
    username="user1" \
    password="$(kubectl get secret kafka-user-passwords --namespace workspace -o jsonpath='{.data.client-passwords}' | base64 -d | cut -d , -f 1)";
