Fabric8 Kubernetes Client 6.4.1 is now available!

On behalf of the Fabric8 team and everyone who has contributed, I'm happy to announce that the Fabric8 Kubernetes Client 6.4.1 has been released and is now available from Maven Central 🎉.

Thanks to all of you who have contributed with issue reports, pull requests, feedback, and spreading the word with blogs, videos, comments, and so on. We really appreciate your help, keep it up!

What's new?

Without further ado, let's have a look at the most significant updates:

• Vert.x HttpClient implementation
• Java type generation from remote CRDs
• @KubernetesTest improvements
• 🐛 Many other bug fixes and minor improvements

You can find the full changelog for this version in our GitHub release page.

Vert.x HttpClient implementation

This release includes yet another HttpClient implementation as an alternative to the OkHttpClient based implementation that is configured by default. Big shout out to Steven Hawkins and Julien Viet who made this possible.

You can start using the new Vert.x implementation by configuring the Fabric8 Kubernetes Client dependency in your pom.xml as follows:

<dependency>
  <groupId>io.fabric8</groupId>
  <artifactId>kubernetes-client</artifactId>
  <version>6.4.1</version>
  <exclusions>
    <exclusion>
      <groupId>io.fabric8</groupId>
      <artifactId>kubernetes-httpclient-okhttp</artifactId>
    </exclusion>
  </exclusions>
</dependency>
<dependency>
  <groupId>io.fabric8</groupId>
  <artifactId>kubernetes-httpclient-vertx</artifactId>
  <version>6.4.1</version>
</dependency>

Java type generation from remote CRDs

The Fabric8 Kubernetes Client now supports generating Java types from remote Custom Resource Definitions (CRDs) to provide a better experience. This means that you won't need to have the CRD locally in your project anymore. You won't need complex builds either that include additional steps to download the CRD from a remote location.

@KubernetesTest improvements

In addition to several other minor enhancements, we've improved the @KubernetesTest annotation to allow opting out of creating an ephemeral namespace for your tests.

Using this release

If your project is based on Maven, you just need to add the Fabric8 Kubernetes Client to your Maven dependencies:

<dependency>
  <groupId>io.fabric8</groupId>
  <artifactId>kubernetes-client</artifactId>
  <version>6.4.1</version>
</dependency>

If your project is based on Gradle, you just need to add the Fabric8 Kubernetes Client to your Gradle dependencies:

dependencies {
  api "io.fabric8:kubernetes-client:6.4.1"
}

Once your project is ready, you can create a new instance of the client to perform operations. In the following code snippet, I show you how to instantiate the client and retrieve a list of Pods:

try (KubernetesClient client = new KubernetesClientBuilder().build()) {
  client.pods().list().getItems().forEach(p -> System.out.println(p.getMetadata().getName()));
}
