可以在YAML文件中使用抽象吗？

是否可以使用

参数

或

抽象

来最小化YAML文件中的重复代码

我正在编写一个触发部署的YAML文件，在部署之前和之后，我希望调用一个空闲通道，指示部署正在开始、完成，以及部署失败的情况

这是我写的，但感觉太冗长了：

example_deploy:
    - call: notify
    in:
      msgText: "Deployment starting for environment *${environment}*"
    - try:
      - ${oneops.environmentCommitAndDeploy(environment = 'production', platform = '${platform}', deployAllPlatforms = false )}
      error:
    - log: "Error trying to deploy: ${lastError.cause}"
    - call: notify
      in:
        msgText: " :fire: Deployment failed for environment *${environment}* http://concord.com/#/process/${txId}/log"
    - exit
  - call: notify
    in:
      msgText: " :party: Deployment succeeded for environment *${environment}* http://concord.com/#/process/${txId}/log"

现在，如果我想让

example\u deploy\u 2

做同样的事情，我需要重写所有的代码吗？或者有没有一种方法可以让“函数”或抽象YAML的重复部分

更新 我曾使用

call

来抽象对slack的调用，但现在我想知道是否可以对slack进行一般调用并动态更新消息-因为现在我正在重复传递给定义为

call

ed的代码块的参数

示例

  example_deploy:
    - call: slack_start_deploy
    - try:
      - ${transitionVariableUpdate(platform = '${platform}', environment = '${environment}', component = '${component_ear}' variables = { appVersion = '${BRANCH_NAME}-${BUILD_NUMBER}' })}
      - ${environmentCommitAndDeploy(environment = 'qa', platform = '${platform}', deployAllPlatforms = false )}
      error:
    - log: "Error trying to deploy: ${lastError.cause}"
    - call: slack_deploy_error
    - exit
  - call: slack_deploy_success

  slack_start_deploy:
  - slack.postMessage:
      text: "${entryPoint} Deployment starting for environment *${environment}*"
      channelId: ${alerts}
      username: ${slackname}
      iconEmoji: ${slackEmojiConcord}

  slack_deploy_error:
  - slack.postMessage:
      text: " :fire: ${entryPoint} Deployment failed for environment *${environment}* http://concord.com/#/process/${txId}/log"
      channelId: ${alerts}
      username: ${slackname}
      iconEmoji: ${slackEmojiConcord}

  slack_deploy_success:
  - slack.postMessage:
      text: " :party: Deployment succeeded for environment *${environment}* http://concord.com/#/process/${txId}/log"
      channelId: ${alerts}
      username: ${slackname}
      iconEmoji: ${slackEmojiConcord}

YAML规范中唯一允许 尽量减少重复就是使用 在一个节点上 使用别名引用该节点。这适用于两个叶节点 （即任何类型的标量值）和集合节点 （映射、序列）。锚定集合的别名 “替换”集合下的整个子树

---

除此之外，还有

您的示例无效YAML
错误：
是一个与前面的序列项缩进相同的映射项，
-call:
是一个与
exampel\u deplay:
键缩进相同的序列项。你不能把这样的收藏混合在一起YAML@anthon别告诉我细节了，我对大局感兴趣。
