Building a Spring Native application on my Docker Image

I am building my spring boot native application on an alpine (openjdk:13-alpine) docker image.

./mvnw spring-boot:build-image -DskipTests

When doing this I got an error :

[INFO] Building image 'docker.io/library/bff-distributor:0.0.1-SNAPSHOT'

My gitlab.ci configuration

build:
  image: openjdk:13-alpine
  stage: build
  script:
    - chmod 755 ./mvnw
    - ./mvnw spring-boot:build-image -DskipTests

For information : I need it to be running on a docker image as the building it's part of my gitlab ci/cd stage.

As the link provided Scott says, you should use Docker in Docker to do what you want.

So, replace the openjdk image by the docker image (https://hub.docker.com/_/docker) and activate the dind service. As you need Java for the Maven execution, you can simply install jdk in the "before_script" section.

Here is my gitlab-ci script for the same kind of project :

  variables:
    DOCKER_HOST: tcp://docker:2375
    DOCKER_TLS_CERTDIR: ""
  image: docker:20.10.8-dind-alpine3.13
  services:
    - docker:20.10.8-dind
  stage: build_push
  before_script:
    - apk add --update openjdk11
  script:
    - chmod 755 ./mvnw
    - ./mvnw spring-boot:build-image
