AWS CloudFormation 无法使用 CodeDeploy blue/green 部署创建 Stack

Question

我正在尝试使用 CloudFormation 和 ECS 服务部署新堆栈，使用 CodeDeploy 启动类型启用 blue/green 部署。

在通过 CloudFormation 执行 blue/green 部署的 User Guide 中，他们声明如下：

To enable CloudFormation to perform blue/green deployments on a Stack, include the following information in its stack template:

At least one of the ECS resources that will trigger a blue/green deployment if replaced during a stack update. Currently, those resources are AWS::ECS::TaskDefinition and AWS::ECS::TaskSet.

当我排除 AWS::ECS::TaskSet 时，堆栈创建失败并且我收到以下错误：

Transform AWS::CodeDeployBlueGreen failed with: Failed to transform template. 
ECSAttributes must include TaskSets in AWS::CodeDeploy::BlueGreen Hook

如果我添加 AWS::ECS::TaskSet，堆栈将无法创建并出现以下错误：

Resource handler returned message: 
"Invalid request provided: Amazon ECS does not support task set management on services where deployments 
are controlled by AWS CodeDeploy. 
(Service: AmazonECS; Status Code: 400; Error Code: InvalidParameterException; 
Request ID: 61b8c146-3ae9-4bc2-ac5c-08a11e194f06; Proxy: null)" 
(RequestToken: 86a8a3a5-fe89-9939-15c2-45b08b28c3f3, HandlerErrorCode: InvalidRequest)

这些是我的堆栈模板的相关部分：

如何更新我的模板以允许通过 CodeDeploy blue/green 部署策略？

Answer 1

G/B 使用 CFN 的部署是 EXTERNAL，不是 CODE_DEPLOY。您的模板可能还有许多其他问题，但您当前的错误与使用错误 DeploymentController 有关。请研究 AWS 文档和示例：

Perform ECS blue/green deployments through CodeDeploy using AWS CloudFormation

Answer 2

确切地说，AWS 不支持 EC2/ASG 上的蓝绿部署...！我刚刚发现的最简单的方法是使用 In-Place 方法创建部署组 && 然后手动将部署组配置从 In-place 更改为 Blue Green

或者您可以使用 lambda 函数，但自定义它有点困难

希望这对你有所帮助
