OpenJDK (Open Java Development Kit) is a free and open source implementation of the Java Platform, Standard Edition (Java SE). OpenJDK is the official reference implementation of Java SE since version 7.
The OpenJDK development image is intended to be used as a build environment. For runtime, use the OpenJDK runtime image.
To compile and deploy an application, copy the sources and build the binary:
# Build the application using the OpenJDK development image
FROM registry.opensuse.org/opensuse/bci/openjdk-devel:17 as build
WORKDIR /app
COPY . ./
RUN javac Hello.java
# Bundle the application into OpenJDK runtime image
FROM registry.opensuse.org/opensuse/bci/openjdk:17
WORKDIR /app
COPY --from=build /app/Hello.class /app
CMD ["java", "Hello"]
Build and run the container image:
$ podman build -t my-java-app .
$ podman run -it --rm my-java-app
There are situations, where you don't want to run an application inside a container.
To compile the application, without running it inside a container instance, use the following command:
$ podman run --rm -v "$PWD":/app:Z -w /app registry.opensuse.org/opensuse/bci/openjdk-devel:17 javac Hello.java
The OpenJDK 17 development image includes Git and Apache Maven. Apache Ant is available in the repositories.
