Terraform 未部署 api 网关阶段

【问题标题】：Terraform not deploying api gateway stageTerraform 未部署 api 网关阶段
【发布时间】：2016-12-19 01:16:27
【问题描述】：

我一直在尝试使用 terraform 创建 API 网关端点。除了部署阶段的最后一部分之外，一切似乎都在工作。

运行 terraform apply 后，我进入控制台，发现部署没有发生。我需要手动单击 Deploy Api 才能使其正常工作。

这是 api 网关的 terraform 文件。

图表还有我在上面的 tf 文件中没有提供的其他资源。它只有 API GW 有问题。顺便说一句，我可以从控制台测试 API，它工作正常。我无法从我的本地邮箱或邮递员执行它。

知道我做错了什么吗？

【问题讨论】：

  • 这是第一次部署的情况，还是将来发生变化时的部署？后者在 GH 上有一个未解决的问题：github.com/hashicorp/terraform/issues/6613
  • 我猜即使是第一次部署也没有用。我销毁了整个堆栈并再次应用它。仍然看不到部署。当 terraform plan 列出所有需要应用的更改时，部署资源会列在最顶部。这是否意味着首先部署？
  • 它绝对不会首先运行，因为它至少依赖于 2 个资源（aws_api_gateway_rest_api 和 aws_api_gateway_method），而这又可能依赖于其他东西。我必须运行你的 TF 才能看到，但不幸的是，这必须等到今晚。如果您可以将terraform graph 的输出编辑到您的问题中，可能会很有趣？

【解决方案1】：

TF 不部署 API，此链接可能对您有所帮助：https://medium.com/coryodaniel/til-forcing-terraform-to-deploy-a-aws-api-gateway-deployment-ed36a9f60c1a

我已经通过添加变量 deploy_at 来修复我的问题：

resource "aws_api_gateway_deployment" "api_ingest_deployment" {
  depends_on = ["aws_api_gateway_method.xxx",
                "aws_api_gateway_integration.yyy",
                "aws_api_gateway_integration.zzz",
                "aws_api_gateway_integration.www",
  ]
  rest_api_id = "${aws_api_gateway_rest_api.foo.id}"
  stage_name = "${var.environment}"

  variables {
    deployed_at = "${timestamp()}"
  }
}

缺点是如果这样做，它总是会部署，即使没有变化

【讨论】：

  • 实际上，我刚刚也检查了这个 GitHub 问题 github.com/hashicorp/terraform/issues/6613 这样做：资源 "aws_api_gateway_deployment" "default" { ... stage_description = "${md5(file("api_gateway.tf" ))}" ... } 更聪明，会迫使你部署更少
  • 我在这个问题上浪费了几个小时。谢谢你告诉我！
  • Antonio 的回答帮助了我，这篇文章的解决方案似乎“更好”（解决方法，但有效）。应该是可接受的答案吗？
【解决方案2】：

当我收到此错误时，这里没有其他解决方案对我有用：

BadRequestException: Active stages pointing to this deployment must be moved or deleted

This is the solution 对我有用：

resource "aws_api_gateway_deployment" "api_deployment" {
  rest_api_id       = aws_api_gateway_rest_api.api.id
  stage_name        = "default"
  stage_description = "Deployed at ${timestamp()}"

  lifecycle {
    create_before_destroy = true
  }
}

在 Terraform 0.12.24 上测试

【讨论】：

  • 谢谢，您的解决方案在 TF 0.12.24 上也对我有用
【解决方案3】：

来自aws_api_gateway_deployment：

resource "aws_api_gateway_deployment" "example" {
  rest_api_id = aws_api_gateway_rest_api.example.id

  triggers = {
    # NOTE: The configuration below will satisfy ordering considerations,
    #       but not pick up all future REST API changes. More advanced patterns
    #       are possible, such as using the filesha1() function against the
    #       Terraform configuration file(s) or removing the .id references to
    #       calculate a hash against whole resources. Be aware that using whole
    #       resources will show a difference after the initial implementation.
    #       It will stabilize to only change when resources change afterwards.
    redeployment = sha1(jsonencode([
      aws_api_gateway_resource.example.id,
      aws_api_gateway_method.example.id,
      aws_api_gateway_integration.example.id,
    ]))
  }

  lifecycle {
    create_before_destroy = true
  }
}

您需要定义应该触发新部署的触发器，我在没有id 的情况下使用它，它工作得很好。

【讨论】：

    【解决方案4】：

    通常代码更改是在 lambda 级别。因此，您可以将 lambda 代码版本作为变量插入，并将其添加到您有 api 部署的同一模块中。这样它只会在 lambda 代码更改时部署。

    【讨论】：

      【解决方案5】：

      您需要注意几件事。

      1. 正确提及依赖项以确保在执行集成和方法块之后执行部署块（尤其是当您有任何授权方时）。

      2. 在变量中添加时间戳函数，以便在所有依赖块执行完毕后立即部署。

          resource "aws_api_gateway_deployment" "mydeployment" {
  depends_on =["aws_api_gateway_method.mymethod","aws_api_gateway_integration.myintegration"]
  rest_api_id = "${aws_api_gateway_rest_api.myapi.id}"
  stage_name = "dev"
  variables = {
     deployed_at = "${timestamp()}"
  }
}

      【讨论】：

        【解决方案6】：

        如果您使用的是 swagger 模板和 terraform ver >= 0.12，那么您可以为 MD5 计算提供 swagger 文件，如下所示。这很完美。

        resource "aws_api_gateway_deployment" "deploy_stage" {
  rest_api_id = aws_api_gateway_rest_api.product_api.id
  stage_name  = var.stage_name
  stage_description = md5(file("swagger_api.yml"))
}

          【解决方案7】：

          遇到同样的问题。 遇到以下问题：

          1. lifecycle { create_before_destroy = false }

          我不得不将其设置为 false，因为我有一个 options 方法被添加到与 get 相同的 uri 中。当我尝试使用打开的标志运行构建时，出现以下错误

          创建 API 网关部署时出错：BadRequestException：没有为方法定义集成

          1. 之后我开始遇到问题

          BadRequestException：必须移动或删除指向此部署的活动阶段

          经过调查，我发现这与我的 terraform 脚本中发生的自定义域映射有关。手动删除映射并运行 Jenkins Job 后解决了这个问题。

          1. 我做的最后一件事是在应用 terraform 计划和 terraform 之前在我的 jenkins 文件中使用以下脚本。我知道这是一个 hack，但这是我能想到的最好的方法。

          /usr/local/bin/terraform destroy -target aws_api_gateway_base_path_mapping. -auto-approve

          这解决了这个问题。我查看了多个博客，他们提到将生命周期标志设置为 true。但我不能这样做，因为它造成了上述问题。
