amazon-web-services - 将 Bitbucket 管道变量传递到 Cloudformation

Question

我无法将 Bitbucket 存储库变量传递到我的 AWS Cloudformation 模板。我需要传递 $BITBUCKET_BUILD_NUMBER。我可以将其回显到 Bitbucket 管道，但该变量永远不会在 Cloudformation 参数中被替换。

bitbucket-pipelines.yml:

pipelines:
  branches:
    master: 
      - step:
          name: Deploy (Dev)
          deployment: dev
          script:
            - export PARAMETERS=$(cat ./parameters.json)
            - echo "BITBUCKET_BUILD_NUMBER is $BITBUCKET_BUILD_NUMBER"
            - pipe: atlassian/aws-cloudformation-deploy:0.18.0
              variables:
                STACK_NAME: 'dev-be-uservice'
                TEMPLATE: 'cloudformation.yml'
                STACK_PARAMETERS: $PARAMETERS

参数.json:

[
  {
    "ParameterKey": "BuildTag",
    "ParameterValue": "$BITBUCKET_BUILD_NUMBER"
  }
]

cloudformation.yml:

Parameters:
  BuildTag:
    Description: The Docker Tag
    Type: String

在 parameters.json 中，我尝试了 "$BITBUCKET_BUILD_NUMBER"、"${BITBUCKET_BUILD_NUMBER}" 等

Cloudformation 始终将 BuildTag 显示为未替换的字符串 ($BITBUCKET_BUILD_NUMBER)，而不是内部版本号 (2)。

您需要在部署之前评估文件中的环境变量。为此，您可以使用 envsubst:

pipelines:
  branches:
    master: 
      - step:
          name: Deploy (Dev)
          deployment: dev
          script:
            - apt-get -y update && apt-get -y install gettext-base
            - export PARAMETERS=$(envsubst < ./parameters.json)
            - echo "BITBUCKET_BUILD_NUMBER is $BITBUCKET_BUILD_NUMBER"
            - pipe: atlassian/aws-cloudformation-deploy:0.18.0
              variables:
                STACK_NAME: 'dev-be-uservice'
                TEMPLATE: 'cloudformation.yml'
                STACK_PARAMETERS: $PARAMETERS

例如:

$ cat file
[
  {
    "ParameterKey": "BuildTag",
    "ParameterValue": "$BITBUCKET_BUILD_NUMBER"
  }
]
$ export BITBUCKET_BUILD_NUMBER=1.0.0
$ export PARAMETERS=$(envsubst < file)
$ echo "$PARAMETERS"
[
  {
    "ParameterKey": "BuildTag",
    "ParameterValue": "1.0.0"
  }
]
