java.io.IOException: native write() failed : Broken pipe

I’m using the bmuschko/gradle-docker-plugin to build an image for a Spring Boot application. The plugin uses docker-java for the remote tasks.

FROM azul/zulu-openjdk-alpine:11
ADD libs/app-0.0.1-SNAPSHOT.jar /app/
ADD distributions/health-probe.tgz /
RUN mv /health-probe* /scripts
ENTRYPOINT ["java"]
CMD ["-jar", "/app/app-0.0.1-SNAPSHOT.jar"]

This Dockerfile can be used to successfully build an image from the command line but fails with the following exception when ran from Gradle:

Error during callback

It turns out that docker image names can only contain lowercase letters.

@asarkar Maybe you can try to see how you are naming the image you are trying to build. In micronaut’s case it takes the name from rootProject.name in settings.gradle

[Deepakkoli93]

@asarkar @bmuschko @bsideup I may have found a way to reproduce this, at least via the gradle-docker-plugin which micronaut uses to build native docker images. If any upper case letters are present in the value of rootProject.name key in settings.gradle, image building will break. Example, rootProject.name="myapp" will work but rootProject.name="Myapp" will NOT work

@bsideup Does this give any hint as to where the problem is?
