boxcutter/eclipse-temurin repository overview

⁠eclipse-temurin

Eclipse Temurin is the open source Java SE build from the Eclipse Adoptium project, based on OpenJDK.

This image packages releases from: https://github.com/adoptium/containers⁠

Image source: https://github.com/boxcutter/oci/tree/main/openjdk/eclipse-temurin⁠

This is an unofficial repackaging of the unmodified Eclipse Temurin binaries and is not produced, endorsed or supported by the Eclipse Adoptium project or the Eclipse Foundation. The official images are at https://hub.docker.com/_/eclipse-temurin⁠, and more about Temurin is at https://adoptium.net/⁠.

⁠Tags

Use the JDK to compile code and the smaller JRE to run it. The 21 and 25 JDK images start jshell by default.

⁠Using Eclipse Temurin

⁠Compiling and running a Java program

docker run -it --rm \
  --mount type=bind,source="$(pwd)",target="/usr/src/app" \
  --workdir /usr/src/app \
  docker.io/boxcutter/eclipse-temurin:8-jdk \
    bash -c "javac Main.java && java Main"

⁠Running a JAR

docker run -it --rm \
  --mount type=bind,source="$(pwd)",target="/usr/src/app" \
  --workdir /usr/src/app \
  docker.io/boxcutter/eclipse-temurin:8-jre \
    java -jar app.jar

⁠Adding CA certificates

Set USE_SYSTEM_CA_CERTS=1 and mount your certificates (*.crt files) on /certificates. On startup, the entrypoint adds them, along with the system CA certificates, to the JVM truststore:

docker run -it --rm \
  --mount type=bind,source="$(pwd)/certs",target=/certificates \
  --env USE_SYSTEM_CA_CERTS=1 \
  docker.io/boxcutter/eclipse-temurin:8-jre \
    java -jar app.jar

When the container runs as root, the certificates are also added to the system CA store so tools like curl and wget trust them.
