I was trying to setup a build trigger for an kotlin app that is build using gradle. For that I put together the following Dockerfile:
FROM gradle:jdk8 as builder
WORKDIR /home/gradle/project
COPY . .
WORKDIR ./Kuroji-Eventrouter-Server
RUN gradle shadowJar
FROM openjdk:8-jre-alpine
WORKDIR /app
COPY --from=builder /home/gradle/project/Kuroji-Eventrouter-Server/build/libs/kuroji-eventrouter-server-*-all.jar kuroji-eventrouter-server.jar
ENTRYPOINT ["java", "-jar", "kuroji-eventrouter-server.jar"]
And that file works on my machine with docker build and it starts normally on google container registry however during the RUN gradle shadowJar
task it crashes with some gradle error:
Step 5/9 : RUN gradle shadowJar
---> Running in ddd190fc2323
Starting a Gradle Daemon (subsequent builds will be faster)

I tried building the Image on docker HUB and the same thing happend: https://hub.docker.com/r/usbpc/kuroji-eventrouter-server/builds/bnknnpqowwabdy82ydxiypc/
This is very confusing to me as I thought containers should be able to run anywhere and not depend on the enviroment. What can I do to make google build my container?

The problem was a file permission problem. Using the --stacktrace option I found that the gradle process didn't have permissions to create a folder inside the sources.
The solution I would like to do is use the --chown=gradle:gradle
option on the COPY instruction, unfortunatly this it not supported in the google cloud yet.
So the solution is to add USER root
before executing the gradle build.
