如何根据gitlabci上的规则定义全局变量？

Question

如何根据gitlabci上的规则定义全局变量？

我在这个脚本中有一个语法错误，我想知道如何修复它。我的目标是根据我的分支使用不同的环境变量。

是否可以为两个阶段(构建和部署)定义一次环境变量列表？

如果没有，我如何减少和简化我的脚本以避免冗余？我测试了锚点，但是基于我的分支为我的所有脚本定义全局环境变量的可能性真的很棒！

rules:
  - if: $CI_COMMIT_BRANCH == /develop/
    variables:
      BUILD_ENV: "build:staging"
      CLUSTER_NAME: "STAGING"
      SERVICE_NAME: "WebappSTAGING"
      TASK_DEFINITION_NAME: "FlaskSTAGING"
      S3_BUCKET_URL: ""
  - if: $CI_COMMIT_BRANCH == /master/
    variables:
      BUILD_ENV: "build"
      CLUSTER_NAME: ""
      SERVICE_NAME: ""
      TASK_DEFINITION_NAME: ""
      S3_BUCKET_URL: ""

您需要在全局workflow关键字下定义您的规则，以消除语法错误。有了这个设置，只有当提交分支是develop或master时，才会创建管道，并且应该相应地设置变量。

workflow:
  rules:
    - if: $CI_COMMIT_BRANCH == /develop/
      variables:
        BUILD_ENV: "build:staging"
        CLUSTER_NAME: "STAGING"
        SERVICE_NAME: "WebappSTAGING"
        TASK_DEFINITION_NAME: "FlaskSTAGING"
        S3_BUCKET_URL: ""
    - if: $CI_COMMIT_BRANCH == /master/
      variables:
        BUILD_ENV: "build"
        CLUSTER_NAME: ""
        SERVICE_NAME: ""
        TASK_DEFINITION_NAME: ""
        S3_BUCKET_URL: ""
