如何使用Terraform和AWS API Gateway创建API代理

提问于

我正在尝试使用Terraform能够在AWS上的API网关中 Build 一个简单的API代理 . 基本上，我想包装root并将请求代理回另一个 endpoints . 它可能是最简单的设置，我似乎无法让它在Terraform中工作 .

您将在下面找到该脚本 . 此时，我能够创建REST API，定义资源，创建方法，但似乎没有任何方法可以定义它的终点 .

provider "aws" {
    region = "us-east-1"
}
resource "aws_api_gateway_rest_api" "TerraTest" {
  name = "TerraTest"
  description = "This is my API for demonstration purposes"
}

resource "aws_api_gateway_resource" "TerraProxyResource" {
  rest_api_id = "${aws_api_gateway_rest_api.TerraTest.id}"
  parent_id = "${aws_api_gateway_rest_api.TerraTest.root_resource_id}"
  path_part = "{proxy+}"
}

resource "aws_api_gateway_integration" "integration" {
    rest_api_id = "${aws_api_gateway_rest_api.TerraTest.id}"
    resource_id = "${aws_api_gateway_resource.TerraProxyResource.id}"
    http_method = "${aws_api_gateway_method.mymethod.http_method}"

    type = "HTTP_PROXY"
    uri = "http://api.endpoint.com/{proxy+}"
}

这里我将类型设置为proxy，但我认为URI不是设置 endpoints 的正确属性 .

resource "aws_api_gateway_method" "mymethod" {
  rest_api_id = "${aws_api_gateway_rest_api.TerraTest.id}"
  resource_id = "${aws_api_gateway_resource.TerraProxyResource.id}"
  http_method = "ANY"
  authorization = "NONE"
}

我希望这里的某个地方能够创建到其他 endpoints 的映射，但似乎没有任何属性 . （https://github.com/hashicorp/terraform/blob/master/builtin/providers/aws/resource_aws_api_gateway_method.go）

resource "aws_api_gateway_api_key" "TerraTestKey" {
  name = "Terra_Test_Key"

  stage_key {
    rest_api_id = "${aws_api_gateway_rest_api.TerraTest.id}"
    stage_name = "${aws_api_gateway_deployment.TerraTestDeployment.stage_name}"
  }
}


resource "aws_api_gateway_deployment" "TerraTestDeployment" {
  rest_api_id = "${aws_api_gateway_rest_api.TerraTest.id}"
  stage_name = "dev"
}

我扫描了源代码，但没有看到任何可以设置的属性 .

任何人都可以分享任何建议/狙击手吗？

    这是显示工作解决方案的相关模块 . 它不是孤立的，因为它依赖于其他地方定义的一些变量，但它应该足以帮助任何努力获得AWS代理设置并且还显示Lambda授权器集成作为奖励 .

    provider "aws" {
  region  = "${var.region}"
  profile = "${var.profile}"
}

data "aws_iam_role" "api_user" {
  role_name = "api_user"
}

module "authorizer_lambda" {
  source   = "../lambda"
  name     = "${var.api_name}-authorizer_lambda"
  filename = "authorizer_lambda"
  runtime  = "nodejs4.3"
  role     = "${data.aws_iam_role.api_user.arn}"
}

resource "aws_api_gateway_authorizer" "custom_authorizer" {
  name                   = "${var.api_name}-custom_authorizer"
  rest_api_id            = "${aws_api_gateway_rest_api.ApiGateway.id}"
  authorizer_uri         = "${module.authorizer_lambda.uri}"
  authorizer_credentials = "${data.aws_iam_role.api_user.arn}"
  authorizer_result_ttl_in_seconds = 1
}

  rest_api_id = "${aws_api_gateway_rest_api.ApiGateway.id}"

  path_part   = "{proxy+}"
}

  resource_id              = "${aws_api_gateway_resource.ApiProxyResource.id}"
    http_method              = "${aws_api_gateway_method.ApiProxyMethod.http_method}"
    type                     = "HTTP_PROXY"
    integration_http_method  = "ANY"
    uri                      = "${format("%s/{proxy}", "${var.base_url}")}"

  request_parameters            = {"method.request.path.proxy" = true}
}
