我TerraForm在应用程序中用作基础架构框架。以下是我用于将python代码部署到lambda的配置。它执行三个步骤：1.将所有依赖项和源代码压缩到一个zip文件中；2.将压缩文件上传到s3存储桶；3.部署到lambda函数。
但是发生的是deploy命令terraform apply将失败，并显示以下错误：
Error: Error modifying Lambda Function Code quote-crawler: InvalidParameterValueException: Error occurred while GetObject. S3 Error Code: NoSuchKey. S3 Error Message: The specified key does not exist.
status code: 400, request id: 2db6cb29-8988-474c-8166-f4332d7309de
on config.tf line 48, in resource "aws_lambda_function" "test_lambda":
48: resource "aws_lambda_function" "test_lambda" {
Error: Error modifying Lambda Function Code praw_crawler: InvalidParameterValueException: Error occurred while GetObject. S3 Error Code: NoSuchKey. S3 Error Message: The specified key does not exist.
status code: 400, request id: e01c83cf-40ee-4919-b322-fab84f87d594
on config.tf line 67, in resource "aws_lambda_function" "praw_crawler":
67: resource "aws_lambda_function" "praw_crawler" {
这意味着s3存储桶中不存在部署文件。但是第二次运行命令时它成功。似乎是时间问题。将zip文件上传到s3存储桶后，该zip文件在s3存储桶中不存在。这就是为什么第一次部署失败。但是几秒钟后，第二个命令成功且非常快速地完成。我的配置文件有问题吗？

您需要正确添加依赖项才能实现此目的，否则，它将崩溃。
首先压缩文件
# Zip the Lamda function on the fly
data "archive_file" "source" {
type = "zip"
source_dir = "../lambda-functions/loadbalancer-to-es"
output_path = "../lambda-functions/loadbalancer-to-es.zip"
}
然后通过指定zip的依赖关系将其上传到s3，source = "${data.archive_file.source.output_path}"这将使其依赖于zip
# upload zip to s3 and then update lamda function from s3
resource "aws_s3_bucket_object" "file_upload" {
bucket = "${aws_s3_bucket.bucket.id}"
key = "lambda-functions/loadbalancer-to-es.zip"
source = "${data.archive_file.source.output_path}" # its mean it depended on zip
}
然后，您就可以很好地部署Lambda了，要使它行得通，请执行以下操作： s3_key = "${aws_s3_bucket_object.file_upload.key}"
resource "aws_lambda_function" "elb_logs_to_elasticsearch" {
function_name = "alb-logs-to-elk"
description = "elb-logs-to-elasticsearch"
s3_bucket = "${var.env_prefix_name}${var.s3_suffix}"
s3_key = "${aws_s3_bucket_object.file_upload.key}" # its mean its depended on upload key
memory_size = 1024
timeout = 900
timeouts {
create = "30m"
}
runtime = "nodejs8.10"
role = "${aws_iam_role.role.arn}"
source_code_hash = "${base64sha256(data.archive_file.source.output_path)}"
handler = "index.handler"
}
