使用terraform部署多个lambda函数

Question

由于此SO应答，请勿将其标记为重复

我有一个"aws_lambda_function"资源，它运行良好。

现在我想部署另一个lambda函数，我尝试用不同的处理程序和别名复制整个块，但它引发了一个错误。有其他方法吗？

提前谢谢。

这是地形代码：

resource "aws_lambda_function" "api_service" {
function_name = "${substr("${local.api_artifact_name}", 0, min(64, length(local.api_artifact_name)))}"
# Artifacts bucket
s3_bucket = "${local.artifacts_bucket_name}"
s3_key    = "${module.artifact-upload.artifact_key}"
# "index" is the filename within the zip file (main.js) and "handler"
# is the name of the property under which the handler function was
# exported in that file.
handler = "index.api"
runtime = "nodejs8.10"
role    = "${module.api-service-iam.iam_role_arn}"
# Optional, but ensures that things don't constantly refresh during local development
source_code_hash = "${base64sha256(file("${local.api_dist_dir}"))}"
environment {
variables  =  {
...
}
}
}

现在资源api_service成功地部署了一个Lambda函数，但我如何才能部署，比如说，5个这样的函数？

All these Lambda functions will be invoked by an API Gateway later.

所以基本上答案一直盯着我的脸。

我复制了整个资源块，并进行了以下更改：

resource "aws_lambda_function" "lambda-1" {
function_name = "lambda-1-${substr("${local.api_artifact_name}", 0, min(64, length(local.api_artifact_name)))}"
# Artifacts bucket
s3_bucket = "${local.artifacts_bucket_name}"
s3_key    = "${module.artifact-upload.artifact_key}"
# "index" is the filename within the zip file (main.js) and "handler"
# is the name of the property under which the handler function was
# exported in that file.
handler = "lambda-1/index.api"
runtime = "nodejs8.10"
role    = "${module.api-service-iam.iam_role_arn}"
# Optional, but ensures that things don't constantly refresh during local development
source_code_hash = "${base64sha256(file("${local.api_dist_dir}"))}"
}
resource "aws_lambda_function" "lambda-2" {
function_name = "lambda-2-${substr("${local.api_artifact_name}", 0, min(64, length(local.api_artifact_name)))}"
# Artifacts bucket
s3_bucket = "${local.artifacts_bucket_name}"
s3_key    = "${module.artifact-upload.artifact_key}"
# "index" is the filename within the zip file (main.js) and "handler"
# is the name of the property under which the handler function was
# exported in that file.
handler = "lambda-2/index.api"
runtime = "nodejs8.10"
role    = "${module.api-service-iam.iam_role_arn}"
# Optional, but ensures that things don't constantly refresh during local development
source_code_hash = "${base64sha256(file("${local.api_dist_dir}"))}"
}

确保它们有不同的函数名

我基本上为每个lambda创建一个目录，并为policy.json、ssm_parameters.json等工件使用命名约定。

1( 我使用外部数据源来获取目录中的lambda函数列表，并获取每个lambda所需的所有元数据2( 我使用count="N"来部署每个lambda资源。
