1.局部/全局环境变量

stages:
  - testing                    # stage编排
  - build
  - deploy
 
    
variables:
    global_var: "全部变量"  #全部变量
  
build_image:
   stage: build
   variables:                #局部环境变量
     my_name: "局部环境变量"  
   tags:
     - shell 
   script:
     - echo "打包镜像"
     - echo "$my_name"      #打印局部环境变量
     - echo "$global_var"   #打印全局环境变量
    
deploy_to_qa:
   stage: deploy
   tags:
     - shell 
   script:
     - echo "部署到QA"

运行结果：

2.判断语句

stages:
  - testing                    # stage编排
  - build
  - deploy
 
workflow:
  rules:
    - if: $CI_COMMIT_BRANCH == "dev"  #如果提交的分支，等于dev，则执行(类似if...else)
      when: always                      
    - when: never                     #类似else

run_test:                     #Job
  stage: testing
  tags:
    - shell                  #Gitlab-runner 
  script:
    - echo "执行测试."
    - chmod +x ./run.sh      # 给run.sh加可执行权限
    - ./run.sh               # 运行外部文件./run.sh

执行结果：（不做，因为在master分支提交的）

3.自定义系统 全局变量

stages:
  - testing                    # stage编排
  - build
  - deploy
 

run_test:                     #Job
  stage: testing
  tags:
    - shell                  #Gitlab-runner 
  script:
    - echo "执行测试."
    - chmod +x ./run.sh      # 给run.sh加可执行权限
    - ./run.sh               # 运行外部文件./run.sh
    - echo "$BAIDU"          # 打印自定义系统全局变量

执行结果：
