draft up fails with spring boot example - minikube 1.9

[cmoulliard]

When we try to build the spring boot example packaged under the master branch of the draft project on minikube 1.9, then it fails

pwd             
/Users/dabou/Temp/to-be-deleted/draft/examples/example-spring-boot
draft up          
Draft Up Started: 'example-spring-boot'
example-spring-boot: Building Docker Image: FAIL ❌  (0.9963s)
example-spring-boot: Build ID: 01C93N2W30345AZJ6SWF1HAM9Y

As debug option doesn't really help and is not really verbose, how can we investigate why build is failing ?

If I get the logs of the draftd pod, then I can figure out the error (= uberjar file not generated locally)

How can we customise the dockerfile created by draft as it contains an error for the example-springboot and should be

FROM maven:3.5-jdk-8 as BUILD

COPY . /usr/src/app
RUN mvn --batch-mode -f /usr/src/app/pom.xml clean package

FROM openjdk:8-jdk
ENV PORT 4567
EXPOSE 4567
COPY --from=BUILD /usr/src/app/target/demo-0.0.1-SNAPSHOT.jar /opt/app.jar
WORKDIR /opt
CMD ["java", "-jar", "app.jar"]

Hey @cmoulliard, after draft create has been called, you should see a Dockerfile present in your local directory. You can make the changes there and commit it to source control.

If you want to customize the default packs, you can create your own custom draft pack repository.

Will either of those solutions work for you?

FYI #590 should also fix this up for you :)
