Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/liberica-jdk:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Compatibility Notes

The liberica-jdk image is a production-ready distribution of OpenJDK provided by Liberica. This image is part of the Chainguard Images collection, which are minimal, regularly-updated container images designed with security in mind. The image can be pulled from cgr.dev and is suitable for use in various environments, including production.

Getting Started

To test the liberica-jdk image, start by pulling the image:

docker pull cgr.dev/ORGANIZATION/liberica-jdk:latest

Replace ORGANIZATION with your organization's name.

Next, run a container using the image you just downloaded:

docker run -it --rm cgr.dev/ORGANIZATION/liberica-jdk:latest java -version

This command will start a container and display the Java version to verify that the image is working correctly.

Create a simple Java application, for example, HelloWorld.java:

    public class HelloWorld {
         public static void main(String[] args) {
              System.out.println("Hello, World!");
         }
    }

Then compile and run the application inside the container:

docker run -it --rm -v $(pwd):/workspace -w /workspace cgr.dev/ORGANIZATION/liberica-jdk:latest javac HelloWorld.java
docker run -it --rm -v $(pwd):/workspace -w /workspace cgr.dev/ORGANIZATION/liberica-jdk:latest java HelloWorld

You should see the output Hello, World!, indicating that the image can compile and run Java applications.

What are Chainguard Containers?

Chainguard's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.

All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a development, or -dev, variant.

In all other cases, including Chainguard Containers tagged as :latest or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.

Although the -dev container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev variant into a more minimal production image.

Need additional packages?

To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl, or API.

To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
