在 Gitlab-ci.yaml Pipeline 中使用 spring-boot:build-image 创建 docker 镜像

Question

我正在尝试使用命令“spring-boot:build-image”而不使用 Dockerfile 在 Gitlab-ci.yaml （管道）中构建 Spring Boot 应用程序的 docker 映像。该命令在终端开发工作站上运行良好。但是 Gitlab 的 CI/CD Pipeline 抛出了错误。如果有人可以提供帮助，请不胜感激。

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.6.4:build-image (default-cli) on project buildpackdemo: Execution default-cli of goal org.springframework.boot:spring-boot-maven-plugin:2.6.4:build-image failed: Connection to the Docker daemon at 'localhost' failed with error "[2] No such file or directory"; ensure the Docker daemon is running and accessible: com.sun.jna.LastErrorException: [2] No such file or directory -> [Help 1]

Gitlab-ci.yaml

maven-build:
  image: maven:3-jdk-11
  stage: build
  script:
    - "mvn spring-boot:build-image"
  artifacts:
    paths:
      - target/*.jar

Answer 1

我遇到了同样的问题，我终于能够通过设置DOCKER_HOST变量来使其工作。所以，事情看起来像这样：

variables:
  DOCKER_HOST: tcp://docker:2375

maven-build:
  image: maven:3-jdk-11
  stage: build
  services:
    - docker:dind
  script:
    - "mvn spring-boot:build-image"
  artifacts:
    paths:
      - target/*.jar

Answer 2

您必须使用Docker 中的 Docker服务来构建映像并通过以下方式添加services：

maven-build:
  image: maven:3-jdk-11
  stage: build
  services:
    - docker:dind
  script:
    - "mvn spring-boot:build-image"
  artifacts:
    paths:
      - target/*.jar
