Helm provides a quick way of setting up a Redis cluster using a pre-made Helm chart.
1. Add the Helm repository containing the Kafka chart you wish to install.I will use for this tutorial bitnami repo.
helm repo add bitnami https://charts.bitnami.com/bitnami
2. Update local Helm repositories.
helm repo update
3. Use helm install
to install the chart. The basic command is as follows:
helm install my-release bitnami/kafka
In short time kafka chart will be deployed and you will see 2 pods (Kafka and zookeeper) up and running. You can check it with command
kubectl get pods
You should see status Running
Now let’s deploy kafdrop – Kafdrop is a UI for monitoring Apache Kafka clusters.
apiVersion: apps/v1 kind: Deployment metadata: name: kafdrop labels: app: kafdrop spec: replicas: 1 selector: matchLabels: app: kafka-1663660788 #name of deployed kafka service template: metadata: labels: app: kafka-1663660788 #name of deployed kafka service spec: containers: - name: kafdrop image: obsidiandynamics/kafdrop:latest ports: - containerPort: 9000 env: - name: KAFKA_BROKERCONNECT value: "kafka-1663660788:9092" #name of deployed kafka service --- apiVersion: v1 kind: Service metadata: name: kafdrop labels: name: kafdrop spec: ports: - port: 9000 targetPort: 9000 name: kafdrop protocol: TCP selector: app: kafka-1663660788 #name of deployed kafka service type: LoadBalancer
Deploy kafdrop with :
kubectl apply -f kafdrop.yaml
Now you can access kafdrop in your browser with http://localhost:9000
