基于Ci/Cd 自动化部署Docker容器

后端项目

.gitlab-ci.yml

git仓库代码根目录新增文件：.gitlab-ci.yml 配置如下

# 前置脚本
before_script:
  # gradlew 添加执行权限
  - chmod +x gradlew
  # 输出当前目录
  - echo $(pwd)

# 定义CI执行的阶段，这里可以自己根据情况定义多少个阶段
stages:
  - run
run:
  stage: run
  only:
   # 代码分支
    - master
  tags:
    # gitlab runner 标签
    - test-runner
  # 运行脚本
  script:
    # 编译docker镜像并发布到私有仓库Harbor
    - ./gradlew bootBuildImage -Dorg.gradle.java.home=/data/jdk-17.0.1
    # 部署docker容器
    - ssh -tt centos@192.168.10.22 /data/test_project/dev-run.sh

前端项目

.gitlab-ci.yml

git仓库代码根目录新增文件：.gitlab-ci.yml 配置如下

# 定义CI执行的阶段，这里可以自己根据情况定义多少个阶段

  tags:
    # gitlab runner 标签
    - test-runner
  before_script:
    # 登录docker
    - docker login -u "appdeployment" -p "11ccbb2594E304e73" "https://hub.lmm.show/"
    # 安装npm依赖
    - npm install
  # 运行脚本
  script:
    # 编译前端项目
    - npm run build
    # 编译docker镜像
    - docker build -t $CI_REGISTRY_IMAGE .
    # 推送docker镜像到hub私有仓库
    - docker push $CI_REGISTRY_IMAGE
