GitLab Shared Runner下npm install后如何构建docker镜像并推送至GitLab Registry

问题场景 #

需求为基于GitLab Shared Runner执行CI流水线，完成Docker镜像构建并推送至GitLab Registry。初始配置中npm install步骤运行无异常，但后续执行docker build操作的job无法正常运行。

初始.gitlab-ci.yml配置 #

image: node:14.17.3

stages:
  - install
  - build

install_dependencies:
  stage: install
  tags:
    - gitlab-org-docker
  script:
    - pwd
    - npm install

build-job:
  stage: build
  image: docker
  tags:
    - gitlab-org-docker
  script:
    - echo "Compiling the code..."
    - echo "build"
    - docker build -t bmw-frontend-app .
    - docker ps

#

解决方案 #

经排查问题为遗漏了*Docker in Docker（Dind）*服务配置，调整后的可运行配置如下：

image: docker:19.03.13

cache:
  key: ${CI_COMMIT_REF_SLUG}
  paths:
  - node_modules/
  - .next/

stages:
  - build

services:
  - docker:19.03.13-dind

build-job:
  stage: build
  before_script:
    - echo docker login $DOCKER_REGISTRY --username $DOCKER_REGISTRY_USER --password-stdin
  tags:
    - gitlab-org-docker
  script:
    - echo "Compiling the code..."
    - echo "build"
    - docker build -t registry.gitlab.com/areum.lee1/bmwgs_frontend . 
    - docker login registry.gitlab.com -u $DOCKER_REGISTRY_USER -p $DOCKER_REGISTRY_PASS
    - docker push registry.gitlab.com/areum.lee1/bmwgs_frontend

核心调整点 #

• 将全局镜像配置改为image: docker:19.03.12
• 新增了services配置块引入Dind服务
