I'll respond in English as you've asked for it!

If you're looking to leverage the power of Kubernetes and need a reliable Java client to interact with your cluster, I highly recommend exploring the following options:

Kubernetes Java Client

One of the most popular and widely-used Java clients for Kubernetes is maintained by Google. You can find the project on GitHub: https://github.com/kubernetes-client/java.

This client provides a comprehensive API for interacting with your Kubernetes cluster, allowing you to perform various operations such as:

The Java client is built on top of the OpenAPI specification and provides a RESTful API for interacting with your cluster. It also supports various authentication mechanisms, including HTTP Basic Auth, Token-based auth, and more.

k8s-java-client

Another excellent option is the k8s-java-client project maintained by Microsoft. You can find it on GitHub: https://github.com/microsoft/k8s-java-client.

This client provides a similar set of features to the Google-maintained client, with some notable differences:

Both clients are actively maintained and have strong communities behind them. You can choose the one that best fits your needs, depending on your use case and personal preferences.

Other Options

While these two clients are some of the most popular options, there are other Java clients available for interacting with Kubernetes. Some notable mentions include:

When selecting a Java client for your project, consider factors like the level of complexity you're comfortable with, the specific features you need, and the level of community support and maintenance you expect. Whichever client you choose, I hope you have a smooth experience working with your Kubernetes cluster in Java!

Java kubernetes client tutorial

I'd be happy to provide a Java Kubernetes client tutorial for you!

Overview

Kubernetes is a popular container orchestration system that automates the deployment, scaling, and management of containers. The Kubernetes API provides a way to interact with the cluster programmatically. In this tutorial, we'll explore how to use the Java client library to connect to a Kubernetes cluster and perform various operations.

Prerequisites

Step 1: Add the Kubernetes Client Library to Your Project

To get started, you'll need to add the Kubernetes client library to your Java project. You can do this by adding the following dependency to your pom.xml file (if using Maven) or your build.gradle file (if using Gradle):

io.kubernetes
kotlin-client
7.0.0-rc.1
dependencies {
implementation 'io.kubernetes:kotlin-client:7.0.0-rc.1'
}

Step 2: Set up Your Kubernetes Configuration

To connect to your Kubernetes cluster, you'll need to provide the API server URL and other configuration settings. You can do this by creating a KubeConfig object:

import io.kubernetes.client.openapi.models.KubeConfig;
KubeConfig config = KubeConfig.builder()
.setApiServerUrl("https://localhost:8443")
.setClusterName("my-cluster")
.build();

Step 3: Create a Kubernetes Client Object

Once you have your KubeConfig object, you can create a Kubernetes client object using the following code:

import io.kubernetes.client.openapi.apis.CoreV1Api;
import io.kubernetes.client.openapi.apis.ExtensionsV1beta1Api;
CoreV1Api coreApi = config.createApiClient(CoreV1Api.class);
ExtensionsV1beta1Api extApi = config.createApiClient(ExtensionsV1beta1Api.class);

Step 4: Use the Kubernetes Client Object

Now that you have your client object, you can use it to perform various operations in your Kubernetes cluster. For example:

// List pods in the default namespace
List pods = coreApi.listNamespacedPod("default").getItems();
// Get a specific pod's details
Pod pod = coreApi.readNamespacedPod("my-pod", "default").get();

This is just a taste of what you can do with the Kubernetes client library. Here are some additional examples to get you started:

Namespace namespace = coreApi.createNamespace("new-namespace", null).get();

Deployment deployment = extApi.deployNamespacedDeployment("my-deployment", "default", deploymentSpec, null).get();

ReplicationController rc = coreApi.readNamespacedReplicationController("my-rc", "default").get();
coreApi.scaleNamespacedReplicationController("my-rc", "default", new ReplicationControllerScaleSpec().withReplicas(3)).get();

Conclusion

In this tutorial, we've covered the basics of using the Java Kubernetes client library to connect to a Kubernetes cluster and perform various operations. With these examples as a starting point, you can begin exploring the full capabilities of the client library and automate your container management workflows with ease.
