Hi i am new to kubernets, i am using minikube single node cluster for local development and testing. My requirement is i need to deploy kafka and zookeeper on minikube and should be used to produce or consume messages.

I followed this link and successfully deployed it on minikube its details are below. I know that this is quite an old post. I was able to run a simple single cluster kafka and zookeeper deployment successfully using minikube v0.

The deployment and service yamls are as below:. You can test your deployment by installing kafkacat client and running the following commands on separate terminal windows:. I was able to successfully run this on minikube versions v0.

If you want to run this on minikube versions v0. In your case you should try with NodePort. Learn more. Kafka deployment on minikube Ask Question. Asked 2 years, 9 months ago.

This exposes Services as type NodePort instead of ClusterIP, making them available for client applications that can access the Kubernetes host.

At this point, the Kafka Cluster is running. I can check the pods and services in the Kubernetes Dashboard as well as through kubectl on the command line. I can get the Port at which I can access the Kafka Brokers:. Initially, no cluster is visible in Kafka Manager. By providing the Zookeeper information highlighted in the figure zookeeper. Finally the eating of the pudding: programmatic production and consumption of messages to and from the cluster.

I am impressed. I have created the Node application and its package. Then added the kafka-node dependency npm install kafka-node —save. Next I created the producer:. It is wonderful. Absolutely great stuff. Lucas Jellema, active in IT and with Oracle since I followed the tutorial step by step but I get the following error for each pod: pod has unbound PersistentVolumeClaims.

The only change I made in the config files is to change the replicas to 1 instead of 3 for zookeeper and kafka. But when I start things up, kafka does not connect to zookeeper. Prepare to shutdown kafka. KafkaServer org. And how do I change it? Lucas, can you please share your yaml files, I have not been able to connect to the service using node producer and consumer.

Thanks for sharing, I think you missed to mention the step to create kafka namespace, kubectl apply -f namespace. I was able to access the manager by editing the kafka-manager Service and changing the type to NodePort. You can do so by running : kubectl edit svc kafka-manager —namespace kafka.

Use the Quick Starts to get started now! For example kubectl get kafka Operator Based What is an operator? Manage Kafka using gitops. For production you can tailor the cluster to your needs, using features such as rack awareness to spread brokers across availability zones, and Kubernetes taints and tolerations to run Kafka on dedicated nodes.

The Kube-native management of Kafka is not limited to the broker: You can manage Kafka topics, users, mirror maker and Kafka Connect using Custom Resources. This means you can use your familiar kubernetes processes and tooling to manage complete Kafka applications.

Strimzi is used by.This weekend, I have worked with a set of K8S resource files that gives me what I need. In a few steps, I can get start a Kafka environment in Minikube, either on my laptop or in a Katacoda environment.

Then execute these four statements to create the Kubernetes resources that run the Kafka cluster. In the Kubernetes dashboard, switch to the kafka-ca1 namespace and look what has been created: Note: it will take some time for all Pods to be running correctly. After a little while, things are likely to get right — unless the minikube cluster is starved of physical resources memory and disk.

Pods were created as well as services, deployments and stateful sets. Zookeeper has been installed as well as three Kafka Broker Pods.

Together these form the Kafka Cluster — a pretty powerful event hub. At this point, the Kafka Cluster is running. I can check the pods and services in the Kubernetes Dashboard as well as through kubectl on the command line. This should list the services in kafka-ca1 namespace, one of which is kafka-manager.

We are looking for the port at which this service is exposed:. In your browser, you can open the Kafka Manager using the minikube cluster IP and the kafka-manager service port:. Note: this is not the creation of new Kafka cluster but instead the registration with Kafka Manager of an existing cluster. As our next step, we need to create a Topic on the Kafka Cluster. Click on Topics, the on Create:. Set the name to the new topic to event-bus.

Accept all other default settings and press Create. Run a Pod on Kubernetes that starts a Node. You can run the application using the EventBusListenerPod.

Before you run the yaml file, check out its contents. You can check in the Kubernetes Dashboard whether the Pod has started running successfully and is now listening to a Kafka Topic:.

Kafka Manager has recognized the listener or consumer:. As a next step, we will run an application that takes input from you — the user — through simple HTTP requests and that turns each request into an event published on the event bus.

The event bus listener application that we launched in the previous section will consume all those events and make them available through the browser. That means we realize communication between two applications that are completely unaware of each other and only need to know about the common platform event-bus capability.

Check in Kubernetes Dashboard or through kubernetes get pods and kubernetes get services if the creation is complete — and what the port is that was assigned to the EventBusPublisherService. The Event Bus Listener application is still running. Through the browser — or by looking at the logs for the Pod — you can check if it has consumed the event that was just published through the Event Bus Publisher application. I am a fan of Katacoda. Katacoda is a cloud platform that provides browser based access to many playgrounds and scenarios for learning about and experimenting with various technologies.

Using Katacoda, anyone can get going with technologies very quickly and without need for local resources. Minikube has been installed and configured in the environment.Deploying and running successfully Kafka in Kubernetes is not the purpose of the guide, however it is interesting to share some tips about this task which can be quite complex.

Confluent provides a very interesting set of configurations with helm that you can use to setup and build your infrastructure in Kubernetes:. The templates provides in this guide are built on top of the Confluent platform and these configurations, which however can be adapted to run on any kind of deployment. Before starting the deployment with helm, you can use the following configuration to create the require storage classes:.

Modify the values. The Kubernetes templates from Yolean has a very high quality content to spin up Zookeeper and Kafka in Kubernetes:.

These configuration samples can be used to deploy a Zookeeper cluster and Kafka cluster in Kube as a statefulSet. The provided sample yaml for Kubernetes can be used minor modifications related to the names of the statefulSet deployments. Wait for a few minutes to get the statefulSet up and running, you can use the following commands to verify the status:. Secrets must be manually created in the namespace. For production servers this number should likely be much larger. Size for Data dir, where ZooKeeper will store the in-memory database snapshots.Edit This Page.

Minikube is a tool that makes it easy to run Kubernetes locally. Minikube runs a single-node Kubernetes cluster inside a Virtual Machine VM on your laptop for users looking to try out Kubernetes or develop with it day-to-day.

This brief demo guides you on how to start, use, and delete Minikube locally. Follow the steps given below to start and explore Minikube. For more information on starting your cluster on a specific Kubernetes version, VM, or container runtime, see Starting a Cluster. Now, you can interact with your cluster using kubectl. For more information, see Interacting with Your Cluster. The hello-minikube Pod is now launched but you have to wait until the Pod is up before accessing it via the exposed Service.

To view the details of your local cluster, copy and paste the URL you got as the output, on your browser. The minikube start command can be used to start your cluster. This command creates and configures a Virtual Machine that runs a single-node Kubernetes cluster. This command also configures your kubectl installation to communicate with this cluster.

If you are behind a web proxy, you need to pass this information to the minikube start command:. To switch back to this context, run this command: kubectl config use-context minikube. You can specify the version of Kubernetes for Minikube to use by adding the --kubernetes-version string to the minikube start command.

To use this feature, you can use the --extra-config flag on the minikube start command. This flag is repeated, so you can pass it several times with several different values to set multiple options. This flag takes a string of the form component. Valid keys can be found by examining the documentation for the Kubernetes componentconfigs for each component.

Here is the documentation for each supported configuration:. This feature also supports nested structs. To change the LeaderElection. The minikube stop command can be used to stop your cluster. This command shuts down the Minikube Virtual Machine, but preserves all cluster state and data.

Starting the cluster again will restore it to its previous state. The minikube delete command can be used to delete your cluster.
