Overview

SapMachine is a binary distribution of the https://openjdk.org/. It is built, quality tested and long-term supported by SAP.

SapMachine is the default Java runtime for SAP's Business Technology Platform and it is also supported as a https://github.com/cloudfoundry/java-buildpack/blob/master/docs/jre-sap_machine_jre.md in the https://github.com/cloudfoundry/java-buildpack.

How to use this Image

You can pull and test the image with the following commands:

console
docker pull amd64/sapmachine:latest
docker run -it amd64/sapmachine:latest java -version

You can also use the SapMachine image as a base image to run your own jar file:

dockerfile
FROM amd64/sapmachine:latest
RUN mkdir /opt/myapp
COPY myapp.jar /opt/myapp
CMD ["java", "-jar", "/opt/myapp/myapp.jar"]

You can then build and run your own Docker image:

console
docker build -t myapp .
docker run -it --rm myapp

Image Variants

The amd64/sapmachine images come in many flavors, each designed for a specific use case.

amd64/sapmachine:<version>

This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.

Some of these tags may have names like jammy or noble in them. These are the suite code names for releases of https://wiki.ubuntu.com/Releases and indicate which release the image is based on. If your image needs to install any additional packages beyond what comes with the image, you'll likely want to specify one of these explicitly to minimize breakage when there are new releases of Ubuntu.

amd64/sapmachine:<version>-alpine

This image is based on the popular [***] available in https://hub.docker.com/_/alpine. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.

This variant is useful when final image size being as small as possible is your primary concern. The main caveat to note is that it does use https://musl.libc.org instead of https://www.etalabs.net/compare_libcs.html, so software will often run into issues depending on the depth of their libc requirements/assumptions. See this Hacker News comment thread for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.

To minimize image size, it's uncommon for additional related tools (such as git or bash) to be included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile (see the https://hub.docker.com/_/alpine/ for examples of how to install packages if you are unfamiliar).
