python-3.x - 无服务器.yml : Reference existing environment variable in another

Question

我有一个 serverless.yml看起来像这样

service: my-service

provider:
  name: aws
  runtime: python3.7
  versionFunctions: false

  environment:
    ACCOUNT_ID: "${file(./serverless.env.yml):${self:provider.stage}.account_id}"
    ANOTHER_VARIABLE: "some text ${ACCOUNT_ID} some other text"

这里，我想引用现有环境ACCOUNT_ID在 ANOTHER_VARIABLE . ${ACCOUNT_ID}不起作用。我还尝试查看无服务器文档，但找不到与此相关的任何内容。

Answer 1

您可以简单地使用 ${self:provider.environment.ACCOUNT_ID} .

service: my-service

provider:
  name: aws
  runtime: python3.7
  versionFunctions: false

  environment:
    ACCOUNT_ID: "${file(./serverless.env.yml):${self:provider.stage}.account_id}"
    ANOTHER_VARIABLE: "some text ${self:provider.environment.ACCOUNT_ID} some other text"
