适用于S3存储桶的Terraform AWS可选日志记录

可以飞。如果要使日志记录的值可选，请首先将模块aws_s3_bucket.tf设置为：

resource "aws_s3_bucket" "b" {
  bucket = "my-tf-test-bucket"
  acl    = "private"

  logging = "${var.logging}"
}

variable "logging" {
  type    = "list"
  default = []
}

然后在一个子文件夹示例中添加您的模板module.tf：

module "s3" {
  source = "../"

  logging = [
    {
      target_bucket = "loggingbucketname"
      target_prefix = "log/"
    },
  ]
}

provider "aws" {
  region  = "eu-west-1"
  version = "2.4.0"
}

这是您具有日志记录的版本。

接下来修改您的module.tf看起来像

  module "s3" {
      source = "../"
   }

    provider "aws" {
      region  = "eu-west-1"
      version = "2.4.0"
    }

那是你没有的版本。适用于：Terraform v0.11.11 + provider.aws v2.4.0

已更新这是v0.12.5的答案。现在的模块是：

resource "aws_s3_bucket" "b" {
  bucket = "my-tf-test-bucket"
  acl    = "private"

  logging {
    target_bucket = var.logging["target_bucket"]
    target_prefix = var.logging["target_prefix"]
  }
}

variable "logging" {
  type=map
  default={
      target_bucket = ""
      target_prefix = ""
  }
}

将模块与日志记录一起使用（模块的路径可能有所不同）：

module "s3" {
  source = "../"
  logging={
    target_bucket = aws_s3_bucket.log_bucket.id
    target_prefix = "log/"
  }
}

provider "aws" {
  region  = "eu-west-1"
  version = "2.34.0"
}

resource "aws_s3_bucket" "log_bucket" {
  bucket = "my-tf-log-bucket"
  acl    = "private"
}

没有：

module "s3" {
  source = "../"
}

provider "aws" {
  region  = "eu-west-1"
  version = "2.34.0"
}
