重用CloudFormation标签列表 [英] Reuse list of CloudFormation tags

问题描述

我有一组相当复杂的CloudFormation模板，可用于配置基础架构的不同环境。但是，我最近收到了用大量标签（例如15个）标记已创建资源的请求。

I have a rather complex set of CloudFormation templates that I use for provisioning the different environments of our infrastructure. However I recently got the request to tag the created resources with a rather extensive list of tags (like 15).

将标签硬编码到每个模板文件中并没有对我来说似乎是个好主意。我宁愿一次创建标签列表，并为每个可标记资源引用它们。问题是：我什至不确定这是否可行。您是否知道可以实现标签的可重用列表的任何方式？

Hardcoding the tags into each of the template file doesn't seem like a good idea to me. I would rather create the list of tags once and refer to them for every taggeable resource. Problem is: I am not even sure this is possible. Do you know of any way that a reusable list of tags can be achieved?

我想这样写：

ECSAutoScalingGroup:
    Type: AWS::AutoScaling::AutoScalingGroup
    Properties: 
        ...
        Tags: !Ref ElTags

而不是

ECSAutoScalingGroup:
    Type: AWS::AutoScaling::AutoScalingGroup
    Properties: 
        ...
        Tags: !Ref ElTags
            - Key: Name
              Value: !Join ["-", [!Ref EnvironmentName, 'ecs-as-group'] ]
              PropagateAtLaunch: true
            - Key: TEAM
              Value: !Ref TeamName
              PropagateAtLaunch: true

推荐答案

您可以轻松地重用标签如果您不将它们传递给模板，而是在部署过程中引用它们。标签将传播到堆栈的所有资源。类似于以下命令的命令可能会满足您的需求：

You can easily reuse tags if you don't pass them to the template but instead reference them during deployment. The tags will be propagated to all ressources of the stack. A command similar to the one below might meet your needs:

aws cloudformation create-stack --stack-name mystack \
--template-body file://my_template.yaml --tags file://my_tags.json

文件my_tags.json的格式为

The file my_tags.json is of the format

[
    {"Key": "mytag", "Value": "val"},
    ...
]

或者，您可以通过CodePipeline部署堆栈，并在模板配置

Alternatively, you could deploy your stack through CodePipeline and define the tags in the template configuration
