Openjdk 11 windows installer4/6/2024 The images for Microsoft Build of OpenJDK are configured by default with the en_US.UTF-8 locale. The folder /home/app is also owned by user app, giving the application a writeable filesystem. In the above example, the application binary is copied as root, since the images remain with root by default. The images come with an app user that can be optionally enabled and used by consuming layers: FROM /openjdk/jdk:17-mariner You may use any base OS and version of your choice.ĬOPY -from=runtime-build /javaruntime $JAVA_HOMEįor more information on creating custom Java runtimes, see Java Runtimes with jlink Non-root user To create a custom Java runtime image, use a multi-stage Dockerfile similar to the following example: # Example of custom Java runtime using jlink in a multi-stage container buildįROM /openjdk/jdk:17-ubuntu as runtime-build Tar xf -C $JAVA_HOME -strip-components 1 -no-same-owner RUN apk add -no-cache fontconfig libretls musl-locales musl-locales-lang ttf-dejavu tzdata zlib \ # (Optional) Add extra packages for fontconfig and ttf-dejavu to support server-side image generation Users are welcome to create container images for Alpine Linux using our binaries.Ĭreate a Dockerfile with the following contents: FROM alpine:latestĮNV LANG='en_US.UTF-8' LANGUAGE='en_US:en' LC_ALL='en_US.UTF-8' While Microsoft does not produce Alpine-based images, we do provide musl-compiled JDK binaries for Alpine Linux. You can also install the JDK using either yum or apt-get, or simply extracting a tar.gz file and configuring JAVA_HOME accordingly. If you prefer to use a different OS base image distribution, you can copy the JDK from an existing pre-built image using the COPY -from instruction in a Dockerfile, similar to the following example: # Example using MS Build of OpenJDK image with a different base imageĮNV JAVA_HOME /usr/lib/jvm/msopenjdk-17-amd64ĬOPY -from=/openjdk/jdk:17-ubuntu $JAVA_HOME $JAVA_HOME Consuming Dockerfiles must use the CMD instruction to complete the command-line arguments of the JVM launcher process.Ĭreate a Dockerfile with the following contents: FROM /openjdk/jdk:17-distroless The ENTRYPOINT of these images is already configured pointing to the java command. Because the distroless images do not contain a complete Linux distribution, there is no shell, for example. They require a different approach to deploying an application. The distroless images are based on the CBL-Mariner 2.0 distribution by Microsoft. # Continue with your application deploymentĬMD How to use these imagesĬreate a Dockerfile with the following contents: # Example using MS Build of OpenJDK image directlyįROM /openjdk/jdk:17-ubuntu To force an architecture inside a Dockerfile, you may use the following: FROM -platform=linux/arm64 /openjdk/jdk:17-mariner AS buildįor more information on building multi-platform container images, check the documentation of your container runtime. To force a pull of an image for a specific architecture, use the following: $ docker pull -platform=linux/arm64 /openjdk/jdk:17-mariner Your container runtime shall pull the right image based on your environment. The images above are offered for both amd64 and arm64 architectures. Note: Images for OpenJDK 8 ship with binaries of Eclipse Temurin, from the Eclipse Adoptium project. The following table shows the tag to use for your Linux distribution and JDK version. To pull the latest image for a specific tag, use the following command: docker pull /openjdk/jdk: The images are published in the Microsoft Container Registry located at /openjdk/jdk. We currently provide Linux-based container images for Ubuntu 20.04 and Microsoft CBL-Mariner. This article provides information on the available container images for the Microsoft Build of OpenJDK.
