Dockerfile.multistage not working (looks like an image issue) #10132

Closed fabstao closed 4 years ago

fabstao commented 4 years ago

Describe the bug Can't build docker native image with the application, can't even copy pom.xml to the build image (quay.io/quarkus/centos-quarkus-maven:19.3.1-java11) it looks like an issue with the image because I can copy files into my own Docker images, even based on CentOS.

Expected behavior Build application into docker container image

Actual behavior Docker build fails in first stage

To Reproduce Steps to reproduce the behavior:

  1. Use a working Quarkus application on a docker enabled host
  2. Move to the project directory (where pom.xml is located)
  3. copy src/main/docker/Dockerfile.multistage .
  4. docker build -t .
  5. Copy error message appears
$ docker build -t quay.io/fabstao/rokostacio2 .

Hi @fabstao,

I should have a look at the .dockerignore file. The file has the following content by default.

*
!target/*-runner
!target/*-runner.jar
!target/lib/*

As you can see, all files are ignored (i.e. pom file) except the artifacts. Hence, you have to adjust the rules according to your needs (e.g. add !pom.xml).
