redblackcs/java repository overview

⁠Java Alpine Image - JRE Headless

Minimal java image with low footprint alpine linux base.

Includes only JRE-Headless package to further reduce the size, as most docker containers use api model so normal JRE (with GUI support) is an overhead.

⁠Using this image

Image tags are of format java:JRE_VERSION

Pull the image from dockerhub⁠

docker pull vsaps/java:21

Copy the required jars/java classes to the image and execute with java

e.g. Dockerfile

FROM vsaps/java:21

RUN mkdir /app
WORKDIR /app

COPY  target/my-jar.jar .
#EXPOSE 8080
ENTRYPOINT ["java", "-jar", "my-jar.jar" ]
