A repo to demonstrate how to use jlink

---

To build image with JDK: docker build -t jvm-in-docker:jdk -f jdk.dockerfile .

To run JDK image: docker run --rm -p 8080:8080 jvm-in-docker:jdk

---

To build JRE image: docker build -t jvm-in-docker:jre -f jre.dockerfile .

To run JRE image: docker run --rm -p 8080:8080 jvm-in-docker:jre

---

To analyze dependencies:

mkdir app
cd ./app
unzip ../app.jar
cd ..
jdeps --print-module-deps --ignore-missing-deps --recursive --multi-release 17 --class-path ./app/BOOT-INF/lib/* ./app.jar
rm -Rf ./app

Should give you:

java.base,java.management,java.naming,java.net.http,java.security.jgss,java.security.sasl,java.sql,jdk.httpserver,jdk.unsupported
