Multi-Stage Spring Boot Dockerization Using Maven

Trying to get the multi-stage Spring Boot application Dockerfile that works.

The idea is to:

  1. Build and package the project using mvn package command
  2. Run the built .jar file

After some research, I found this article. It provides complete Dockerfile, but it does not work for me.

I modified the initial Dockerfile, and now it looks like this:

FROM maven:3.6.2-jdk-8-slim AS MAVEN_BUILD

COPY pom.xml /build/
COPY src /build/src/

WORKDIR /build/

RUN mvn -Dmaven.test.skip=true package -Ptest # This line does not work properly

FROM openjdk:8-jre

WORKDIR /app

COPY --from=MAVEN_BUILD /build/target/platform-0.0.1.jar /app/

ENTRYPOINT ["java", "-jar", "platform-0.0.1.jar"]

I created a docker-compose.yml that tries to build this Dockerfile:

[...]
  api:
    build:
      context: .
      dockerfile: Dockerfile
    depends_on:
      - mysql-db
    ports: 
      - "8080:8085"
[...]

After running the docker-compose up --build -d command, I always get this error: docker-compose log

Am I missing something?

Running the mvn -Dmaven.test.skip=true package -Ptest command in the actual project folder works normally...

The problem was with my docker client installation. It somehow did not setup necessary permissions after installation. On other machines, this Dockerfile works fine.

Well, this was a lesson for some future times.
