Short Description
Java is a concurrent, class-based, and object-oriented programming language.
Full Description


This image is officially deprecated in favor of the openjdk image, and will receive no further updates after 2016-12-31 (Dec 31, 2016). Please adjust your usage accordingly.

The image has been OpenJDK-specific since it was first introduced, and as of 2016-08-10 we also have an ibmjava image, which made it even more clear that each repository should represent one upstream instead of one language stack or community, so this rename reflects that clarity appropriately.

Supported tags and respective Dockerfile links

THESE IMAGES ARE VERY, VERY EXPERIMENTAL; THEY ARE PROVIDED ON A BEST-EFFORT BASIS WHILE docker/docker#15866 IS STILL IN-PROGRESS -- PLEASE DO NOT USE THEM FOR ANYTHING SERIOUS OR IMPORTANT (aside from the important task of CI for testing Docker itself, which is one of their primary purposes for existence)

This image is built from the source of the official image of the same name (java). Please see that image's description for links to the relevant Dockerfiles.

If you are curious about specifically how this image differs, see the Jenkins Groovy DSL scripts in the tianon/jenkins-groovy GitHub repository, which are responsible for creating the Jenkins jobs which build them.

For more information about this image and its history, please see the relevant manifest file (library/java). This image is updated via pull requests to the docker-library/official-images GitHub repo.

For detailed information about the virtual/transfer sizes and individual layers of each of the above supported tags, please see the repos/java/ file in the docker-library/repo-info GitHub repo.

What is Java?

Java is a concurrent, class-based, object-oriented language specifically designed to have as few implementation dependencies as possible. It is intended to allow application developers to "write once, run anywhere", meaning that code that runs on one platform does not need to be recompiled to run on another.

Java is a registered trademark of Oracle and/or its affiliates.

How to use this image

Start a Java instance in your app

The most straightforward way to use this image is to use a Java container as both the build and runtime environment. In your Dockerfile, writing something along the lines of the following will compile and run your project:

FROM java:7
COPY . /usr/src/myapp
WORKDIR /usr/src/myapp
RUN javac
CMD ["java", "Main"]

You can then run and build the Docker image:

$ docker build -t my-java-app .
$ docker run -it --rm --name my-running-app my-java-app

Compile your app inside the Docker container

There may be occasions where it is not appropriate to run your app inside a container. To compile, but not run your app inside the Docker instance, you can write something like:

$ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp java:7 javac

This will add your current directory as a volume to the container, set the working directory to the volume, and run the command javac which will tell Java to compile the code in and output the Java class file to Main.class.

Why is this only OpenJDK/OpenJRE?

As all of the major upstream Linux distributions are unwilling to redistribute Oracle Java in their own distribution channels, we have chosen to follow them. See references below on how each distribution does not distribute Oracle Java.

  • Ubuntu stopped distributing it in the sun-java6 package when Oracle retired the "Operating System Distributor License for Java" (
  • Debian requires users to download the Java tar manually from and then use java-package to install it (
  • The webupd8 PPA for Ubuntu and Debian requires the user to accept the Oracle license in order for their software to download and install Oracle java (
  • Gentoo has a fetch-restriction that requires the user to go to the Oracle website to download the Java tar manually which inclues accepting the license (
  • CentOS requires users to go and download the rpm provided by Oracle at and thus accept the Oracle license (
  • RedHat provides instructions to add a repo that is maintained by Oracle (
