Fabric8 Kubernetes Client 6.3.1 is now available!

On behalf of the Fabric8 team and everyone who has contributed, I'm happy to announce that the Fabric8 Kubernetes Client 6.3.1 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:

• DSL support for server-side apply
• Blocking delete operations
• 🐛 Many other bug fixes and minor improvements

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

DSL support for server-side apply

We've introduced a new DSL method to be able to perform server-side apply operations. Server-side apply was already supported in previous versions of the Fabric8 client. However, performing these operations required a nasty and verbose call to the patch method. With the new DSL methods, it is much easier to perform these requests.

// Before
kubernetesClient.resource(resource).patch(PatchContext.of(PatchType.SERVER_SIDE_APPLY), resource);

// With new server-side apply DSL
kubernetesClient.resource(resource).serverSideApply();
// Or with additional options
kubernetesClient.resource(resource).fieldManager("field-manager").forceConflicts().serverSideApply();

Blocking delete operations

With the release of version 6.0, the delete operations became non-blocking and required an additional waitUntilCondition call to block the current thread until the resource was deleted from the cluster. The following code shows what was proposed in the migration guide:

var resource = kubernetesClient.resource(pod);
resource.delete();
resource.waitUntilCondition(Objects::isNull, 30, TimeUnit.SECONDS);

This release includes a new withTimeout DSL method that will make the delete calls blocking.

kubernetesClient.resource(pod).withTimeout(30, TimeUnit.SECONDS).delete();

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>6.3.1</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:6.3.1"
}

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()));
}
