在我的 Docker 图片上构建 Spring 本机应用程序

Question

我正在 alpine (openjdk:13-alpine) docker 图像上构建 spring 启动 native 应用程序。

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

执行此操作时出现错误：

我的gitlab.ci配置

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

有关信息：我需要它在 docker 图像上运行，因为它是我的 gitlab ci/cd 阶段的一部分。

正如 Scott 所说的 link，你应该在 Docker 中使用 Docker 来做你想做的事。

所以，用docker图片（https://hub.docker.com/_/docker）替换openjdk图片，并激活dind服务。由于 Maven 执行需要 Java，因此只需在“before_script”部分安装 jdk。

这是我的 gitlab-ci 同类项目的脚本：

  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
