Eclipse JKube 1.16 is now available!

On behalf of the Eclipse JKube team and everyone who has contributed, I'm happy to announce that Eclipse JKube 1.16.2 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:

• New Buildpacks based build strategy
• New Helm Lint feature
• Support for Kubernetes Recommended Labels
• Updated base images:
  • Better support for Java 21
  • Jolokia updated to 2.0.0
  • Red Hat UBI based on UBI 9
• 🐛 Many other bug-fixes and minor improvements

New Buildpacks based build strategy

Users can now leverage Cloud Native Buildpacks to build their container images. In addition to the existing docker, jib, and s2i build strategies, JKube now supports the buildpacks strategy.

To enable the buildpacks strategy, you just need to set the jkube.build.strategy property to buildpacks:

<prooperties>
  <jkube.build.strategy>buildpacks</jkube.build.strategy>
</properties>

Or in case you're using Gradle:

jkube.build.strategy=buildpacks

There is no need to have a Pack CLI binary installed in your system, JKube takes care of downloading and wrapping the Pack CLI for you.

Currently, JKube reads your .pack/config.toml file to select the builder image. In case there is no .pack/config.toml file, JKube will use the standard paketobuildpacks/builder:base builder image.

New Helm Lint feature

Eclipse JKube provides now a new feature to lint the Helm charts it generates just by running a simple Maven or Gradle command.

Once you've generated the Kubernetes resources and the Helm charts, you can now examine the generated Helm charts for possible issues.

In case of Maven:

mvn k8s:resource k8s:helm k8s:helm-lint

Or if you're using Gradle:

gradle k8sResource k8sHelm k8sHelmLint

Using this release

If your project is based on Maven, you just need to add the Kubernetes Maven plugin or the OpenShift Maven plugin to your plugin dependencies:

<plugin>
  <groupId>org.eclipse.jkube</groupId>
  <artifactId>kubernetes-maven-plugin</artifactId>
  <version>1.16.2</version>
</plugin>

If your project is based on Gradle, you just need to add the Kubernetes Gradle plugin or the OpenShift Gradle plugin to your plugin dependencies:

plugins {
  id 'org.eclipse.jkube.kubernetes' version '1.16.2'
}
