Question

我已经尝试使用terraform部署1个lambda。问题是-我计划仅使用当前创建的代码部署lambda，如果我需要使用相同的代码但具有不同的环境变量来部署第二，第三和第四rmbda，该怎么办？请参见下面的示例方案

LAMBDA-1 = hello-Earth
ENV VARS:
    KMS-KEY-1 = data.aws_kms_key.key1.id
    KMS-KEY-2 = data.aws_kms_key.key2.id
    ENV = DEV

LAMBDA-2 = hello-Mars
ENV VARS:
    KMS-KEY-1 = data.aws_kms_key.key1.id
    KMS-KEY-2 = data.aws_kms_key.key2.id
    ENV = SQA
    VARIETY = HOT
    SIZE = LARGE

LAMBDA-3 = hello-Neptune
ENV VARS:
    KMS-KEY-1 = data.aws_kms_key.key1.id
    KMS-KEY-2 = data.aws_kms_key.key2.id
    ENV = UAT
    VARIETY = COLD
    SIZE = MEDIUM
    DISTANCE = FAR

LAMBDA-4 = hello-Pluto
ENV VARS
    ENV = PROD
    SIZE = SMALL
    DISTANCE = FAR

aws_lambda_function资源具有一个environment argument。您可以在其中定义环境变量。

因此，您的lambda函数资源将相同，但具有不同的环境参数，如下所示：

resource "aws_lambda_function" "hello-Earth" {
  filename      = "lambda_function_payload.zip"
  function_name = "hello-Earth"
  role          = "${aws_iam_role.iam_for_lambda.arn}"
  handler       = "exports.test"

  source_code_hash = "${filebase64sha256("lambda_function_payload.zip")}"

  runtime = "nodejs8.10"

  environment {
    variables = {
      KMS-KEY-1 = data.aws_kms_key.key1.id
      KMS-KEY-2 = data.aws_kms_key.key2.id
      ENV = "UAT"
      VARIETY = "COLD"
      SIZE = "MEDIUM"
      DISTANCE = "FAR"
    }
  }
}

resource "aws_lambda_function" "hello-Mars" {
  filename      = "lambda_function_payload.zip"
  function_name = "hello-Mars"
  role          = "${aws_iam_role.iam_for_lambda.arn}"
  handler       = "exports.test"

  source_code_hash = "${filebase64sha256("lambda_function_payload.zip")}"

  runtime = "nodejs8.10"

  environment {
    variables = {
      KMS-KEY-1 = data.aws_kms_key.key1.id
      KMS-KEY-2 = data.aws_kms_key.key2.id
      ENV = "SQA"
      VARIETY = "HOT"
      SIZE = "LARGE"
    }
  }
}
