Dockerizing windwos java 32 bit JNI app

_readme.md

This is a complementary material to my blog post: Use wine to run windows JDK on linux. Please check the blogpost for detail on what and why happens here.

Before building the container:

• Place the downloaded jdk-8u191-windows-i586.exe in the same folder as Dockerfile (or if using different JVM version, just adjust the filename).

Dockerfile

FROM ubuntu:18.10

RUN dpkg --add-architecture i386 && \
  apt-get update && \
  apt-get install -y wine32 && \
  apt-get clean -y

COPY jdk-8u191-windows-i586.exe /app/jdk.exe

RUN chmod +x /app/jdk.exe && wine /app/jdk.exe /s

Makefile

LABEL = wine-jdk8-32:2018-11-11
ARCHIVE="wine-jdk8-32"

.PHONY: help
help:
	@echo "build      - image $(LABEL)"
	@echo "save-image - to $(ARCHIVE).tar.gz"
	@echo "load-image - from $(ARHIVE).tar.gz"

.PHONY: build
build:
	docker build . -t $(LABEL)

save-image:
	docker save $(LABEL) > $(ARCHIVE).tar
	gzip $(ARCHIVE).tar

load-image:
	gunzip $(ARCHIVE).tar.gz
	docker load < $(LABEL).tar

run.sh

#!/bin/bash
export DOCKER_IMG="wine-jdk8-32:2018-11-11"
export JAVA_EXE='c:\Program Files\Java\jdk1.8.0_191\bin\java.exe'
export JAR='legacy-app.jar'
export JNA='lib/win32'
export MAIN_CLASS='com.legacy.MainClass'

docker run --rm -v "$PWD:/build" -w /build -it "$DOCKER_IMG" wine "$JAVA_EXE" -cp "$JAR" -Djna.library.path="$JNA" "$MAIN_CLASS"
