| A container image that contains an OpenJDK runtime suitable for running |
| modern web services. |
| |
| |
| == Summary |
| |
| This container image ships the latest OpenJDK feature release from |
| https://jdk.java.net[jdk.java.net] on top of a |
| https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/building_running_and_managing_containers/assembly_types-of-container-images_building-running-and-managing-containers#con_understanding-the-ubi-micro-images_assembly_types-of-container-images[Red |
| Hat UBI Micro] base. |
| |
| The module set was selected for |
| https://gerrit.benkard.de/plugins/gitiles/mulkcms2/[MulkCMS 2], which |
| is a typical Quarkus application. It will very likely work for other |
| typical Quarkus applications. |
| |
| |

| |
| For example, specifying `ALL-MODULE-PATH` includes all modules |
| included in the OpenJDK distribution: |
| |
| [source,dockerfile] |
| ---- |
| RUN /jdk/*/bin/jlink \ |
| -J-XX:MaxRAMPercentage=75 \ |
| --add-modules ALL-MODULE-PATH \ #<1> |
| --compress=1 \ |
| --no-man-pages \ |
| --strip-debug \ |
| --output /java |
| ---- |
| <1> Include all JDK modules. |
| |
| |
| == Usage |
