无法使用 localstack dynamoDB 锁定 terraform 状态：UnrecognizedClientException

问题描述

我一直在尝试创建一个本地开发环境，以在 docker 上运行带有 localstack (https://github.com/localstack/localstack) 的 terraform。

我已经能够创建一个 S3 存储桶来存储 terraform 状态，但我还想将 DynamoDB 模拟为锁。

配置为：

localstack docker-compose.yml:

version: "3.2"
services:
  localstack:
    image: localstack/localstack:latest
    container_name: localstack
    ports:
      - "4563-4599:4563-4599"
      - "8080:8080"
    environment:
      - data_dir=/tmp/localstack/data
      - DEBUG=1
    volumes:
      - "./.localstack:/tmp/localstack"
      - "/var/run/docker.sock:/var/run/docker.sock"

第一个地形：

用作初始引导程序，为 tfstate 锁定创建 s3 tfstate 存储和 DynamoDB 表。

provider "aws" {
  region                      = "us-east-1"
  access_key                  = "foo"
  secret_key                  = "bar"
  skip_credentials_validation = true
  skip_requesting_account_id  = true
  skip_Metadata_api_check     = true
  s3_force_path_style         = true
  endpoints {
    apigateway     = "http://localhost:4566"
    cloudformation = "http://localhost:4566"
    cloudwatch     = "http://localhost:4566"
    dynamodb       = "http://localhost:4566"
    es             = "http://localhost:4566"
    firehose       = "http://localhost:4566"
    iam            = "http://localhost:4566"
    kinesis        = "http://localhost:4566"
    lambda         = "http://localhost:4566"
    route53        = "http://localhost:4566"
    redshift       = "http://localhost:4566"
    s3             = "http://localhost:4566"
    secretsmanager = "http://localhost:4566"
    ses            = "http://localhost:4566"
    sns            = "http://localhost:4566"
    sqs            = "http://localhost:4566"
    ssm            = "http://localhost:4566"
    stepfunctions  = "http://localhost:4566"
    sts            = "http://localhost:4566"
  }
}

resource "aws_s3_bucket" "terraform_state" {
  bucket = "terraform-state"
  acl    = "private"

  versioning {
    enabled = true
  }

  server_side_encryption_configuration {
    rule {
      apply_server_side_encryption_by_default {
        sse_algorithm = "AES256"
      }
    }
  }

  lifecycle {
    prevent_destroy = true
  }
}

resource "aws_s3_bucket_public_access_block" "terraform_state_access" {
  bucket = aws_s3_bucket.terraform_state.id

  block_public_acls       = true
  ignore_public_acls      = true
  block_public_policy     = true
  restrict_public_buckets = true
}

resource "aws_dynamodb_table" "terraform_state_lock" {
  name           = "terraformlock"
  read_capacity  = 5
  write_capacity = 5
  billing_mode   = "PAY_PER_REQUEST"
  hash_key       = "LockID"

  attribute {
    name = "LockID"
    type = "S"
  }
}

第二地形：

创建资源并将状态存储在 s3 中并使用 DynamoDB 创建锁。

terraform {
  backend "s3" {
    bucket                      = "terraform-state"
    key                         = "main/terraform.tfstate"
    region                      = "us-east-1"
    endpoint                    = "http://localhost:4566"
    skip_credentials_validation = true
    skip_Metadata_api_check     = true
    force_path_style            = true
    dynamodb_table              = "terraformlock"
    encrypt                     = true
  }
}

provider "aws" {
  region                      = "us-east-1"
  access_key                  = "foo"
  secret_key                  = "bar"
  skip_credentials_validation = true
  skip_requesting_account_id  = true
  skip_Metadata_api_check     = true
  s3_force_path_style         = true
  endpoints {
    apigateway     = "http://localhost:4566"
    cloudformation = "http://localhost:4566"
    cloudwatch     = "http://localhost:4566"
    dynamodb       = "http://localhost:4566"
    es             = "http://localhost:4566"
    ec2            = "http://localhost:4566"
    firehose       = "http://localhost:4566"
    iam            = "http://localhost:4566"
    kinesis        = "http://localhost:4566"
    lambda         = "http://localhost:4566"
    route53        = "http://localhost:4566"
    redshift       = "http://localhost:4566"
    s3             = "http://localhost:4566"
    secretsmanager = "http://localhost:4566"
    ses            = "http://localhost:4566"
    sns            = "http://localhost:4566"
    sqs            = "http://localhost:4566"
    ssm            = "http://localhost:4566"
    stepfunctions  = "http://localhost:4566"
    sts            = "http://localhost:4566"
  }
}

resource "aws_sqs_queue" "test" {
  name = "test"
  tags = {
    "Environment" = "dev"
  }
}

resource "aws_sns_topic" "test" {
  name         = "test"
  display_name = "test"
}

每当我应用第二个 terraform 时，我都会收到此错误：

❯ terraform apply
Acquiring state lock. This may take a few moments...

Error: Error locking state: Error acquiring the state lock: 2 errors occurred:
        * UnrecognizedClientException: The security token included in the request is invalid.
        status code: 400,request id: UEGJV0SQ614NIEDRB93IAF0JQ7VV4KQNSO5AEMVJF66Q9ASUAAJG
        * UnrecognizedClientException: The security token included in the request is invalid.
        status code: 400,request id: U1IRF6CHGK7RM4SQEGVCSU699RVV4KQNSO5AEMVJF66Q9ASUAAJG



terraform acquires a state lock to protect the state from being written
by multiple users at the same time. Please resolve the issue above and try
again. For most commands,you can disable locking with the "-lock=false"
flag,but this is not recommended.

有没有人试过这个或者想知道是什么导致了它？

解决方法

这可能是因为您尝试使用真正的 DynamoDB，而不是使用 localstack。要使用localstack，您必须添加

dynamodb_endpoint           = "http://localhost:4566"

到您的 backend.S3 配置。更新 backend 设置后，您必须使用 terraform init 重新初始化 TF。
