dockette/java repository overview

⁠JAVA

Ready-to-use images for Java JDK 8 (Eclipse Temurin) & Maven 3.

⁠Discussion / Help

⁠Usage

All images are based on Eclipse Temurin⁠ 8 (the maintained OpenJDK 8 build) on Alpine Linux and are built for linux/amd64. The working directory is /data.

⁠JDK 8

Formerly Oracle JDK 8. Oracle JDK can no longer be downloaded anonymously, so this tag now ships Eclipse Temurin 8 (same image as openjdk8).

docker run --rm \
    -v /path/to/project:/data \
    dockette/java:jdk8 \
    java -version

⁠OpenJDK 8

docker run --rm \
    -v /path/to/project:/data \
    dockette/java:openjdk8 \
    java -version

⁠Maven 3

Formerly Maven 3.5.4 on Oracle JDK 8. Ships settings-docker.xml in /usr/share/maven/ref/. mvn and openjdk-mvn are now the same image.

docker run --rm \
    -v /path/to/project:/data \
    dockette/java:mvn \
    mvn package

docker run --rm \
    -v /path/to/project:/data \
    dockette/java:openjdk-mvn \
    mvn package

⁠Versions

Every image is published as dockette/java:<variant>, where <variant> is jdk8, openjdk8, mvn or openjdk-mvn. YYYY.MM.DD is the release date from VERSION.

There is no latest tag on dockette/java; pick a variant. The separate repositories dockette/jdk8, dockette/openjdk8, dockette/mvn and dockette/openjdk-mvn are no longer updated, use dockette/java:<variant>.

The base images (eclipse-temurin:8-jdk-alpine and maven:3-eclipse-temurin-8-alpine) are not pinned, so every build picks up the current Temurin 8 and Maven 3. Releases are listed on GitHub⁠.

⁠Development

make build-all                  # build all variants for linux/amd64
make test-all                   # java -version (and mvn -v) in every image
make build DOCKER_VARIANT=mvn   # build one variant
make version                    # print VERSION
make release                    # set today's date in VERSION
