/project dir unmodifiable

[crionuke]

Hi, there
When used Dockerfile to multistage build from here got next error:

Step 12/16 : COPY --from=build /project/target/*-runner /work/application
COPY failed: no source files were specified

Think that /project unmodifiable so any changes by RUN ./mvnw -s package just cleared

There is properly Dockerfile for that?

Already fixed: https://quarkus.io/version/main/guides/building-native-image#multistage-docker.

/projects is a volume, it should not be used for sharing content between stages. The fun fact is that it works on Mac, but does not work on Linux.

@cescoffier
Nice, thanks a lot!

But made some fixes to prevent permissions problems with target dir

COPY --chown=quarkus:quarkus mvnw /code/mvnw
COPY --chown=quarkus:quarkus .mvn /code/.mvn
COPY --chown=quarkus:quarkus pom.xml /code/
COPY --chown=quarkus:quarkus settings.xml /code/

[cescoffier]

Do you mean that even with the new one you have permission issues?

[crionuke]

yep, like this - Quarkus code generation phase has failed: Failed to create the output dir /code/target/classes
because ./mvnw package works under quarkus user, but code dir created under root from base image

simple docker file to reproduce

FROM quay.io/quarkus/ubi-quarkus-native-image:21.1.0-java11 AS build
COPY pom.xml /code/
USER quarkus
WORKDIR /code
RUN mkdir target # simulate mvn package to target dir

[cescoffier]

Except that: this pipeline works for me... so it definitely platform specific. I need to test with your permissions to see if that still works.

[cescoffier]

Ok, this is really weird, because it seems that now I need the same permission changes....

Opened quarkusio/quarkus#19988.
