Terraform-通过别名调用lambda的URI是什么? [英] Terraform - what is the URI to invoke lambda via alias?

问题描述

要从API GW调用Lambda，请 invoke_arn 可用于aws_lambda_function资源.

To invoke a Lambda from API GW, invoke_arn can be used for aws_lambda_function resources.

invoke_arn-用于从API网关调用Lambda函数的ARN.

invoke_arn - The ARN to be used for invoking Lambda Function from API Gateway.

resource "aws_api_gateway_integration" "videos" {
  rest_api_id = "${aws_api_gateway_rest_api.24_hour_video.id}"
  resource_id = "${aws_api_gateway_method.videos_get.resource_id}"
  http_method = "${aws_api_gateway_method.videos_get.http_method}"

  integration_http_method = "GET"
  type                    = "AWS_PROXY"  # Lambda Proxy
  uri                     = "${aws_lambda_function.list_videos.invoke_arn}"
}

在 uri 中设置什么以通过别名调用相同的lambda?

What is to set in uri to invoke the same lambda via an alias?

resource "aws_lambda_alias" "lambda_alias_list_videos" {
  name             = "get_video_list"
  description      = "Alias to lambda_list_videos"
  function_name    = "${aws_lambda_function.list_videos.arn}"
  function_version = "$LATEST"
}

推荐答案

aws_lambda_alias 资源创建一个别名，该别名指向Lambda函数的特定版本.别名本身是不可调用的.

The aws_lambda_alias resource creates an alias which points to a specific version of a Lambda function. The alias itself is not invocable.

相反，您应该创建一个指向别名版本的 aws_lambda_function 数据源，并使用其 invoke_arn 属性.您可以在 aws_lambda_function 中使用 qualifier 参数指定版本或别名(请参见

Instead you should create an aws_lambda_function Data Source that points to the aliased version, and use its invoke_arn property. You can use the qualifier argument in an aws_lambda_function to specify either a version or an alias name (see AWS Lambda Invoke Docs for more info).

您的示例显示您已经创建了一个名为 get_video_list 的别名，该别名指向 $ LATEST 版本.您需要创建一个指向该别名的新数据源:

Your example shows you have already created an alias named get_video_list, which points to the $LATEST version. You need to create a new Data Source that points to this alias:

data "aws_lambda_function" "my_function_get_video_list" {
  function_name = "your-function-name"
  qualifier = "get_video_list"
}

您现在可以获取别名函数的调用ARN:

You can now get the invocation ARN of the aliased function:

${aws_lambda_function.my_function.get_video_list.invoke_arn}
