| 18 | A container image that contains an OpenJDK runtime suitable for running |
| 19 | modern web services. |
| 20 | |
| 21 | |
| 22 | == Summary |
| 23 | |
| 24 | This container image ships the latest OpenJDK feature release from |
| 25 | https://jdk.java.net[jdk.java.net] on top of a |
| 26 | 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 |
| 27 | Hat UBI Micro] base. |
| 28 | |
| 29 | The module set was selected for |
| 30 | https://gerrit.benkard.de/plugins/gitiles/mulkcms2/[MulkCMS 2], which |
| 31 | is a typical Quarkus application. It will very likely work for other |
| 32 | typical Quarkus applications. |

| 35 | == Building |
| 36 | |

| 47 | |
| 48 | For example, specifying `ALL-MODULE-PATH` includes all modules |
| 49 | included in the OpenJDK distribution: |
| 50 | |
| 51 | [source,dockerfile] |
| 52 | ---- |
| 53 | RUN /jdk/*/bin/jlink \ |
| 54 | -J-XX:MaxRAMPercentage=75 \ |
| 55 | --add-modules ALL-MODULE-PATH \ #<1> |
| 56 | --compress=1 \ |
| 57 | --no-man-pages \ |
| 58 | --strip-debug \ |
| 59 | --output /java |
| 60 | ---- |
| 61 | <1> Include all JDK modules. |
| 62 | |
| 63 | |
| 64 | == Usage |
| 65 | |
| 66 | [source,shell] |
