amazon-web-services - 适用于 EC2 的 AWS CloudFormation 蓝/绿部署

Question

AWS CloudFormation 是否支持 EC2 的蓝/绿部署？我能够使用 CodeDeploy for EC2 创建蓝/绿部署；但是，我不知道如何使用 CloudFormation 创建一个。 CloudFormation 似乎支持 ECS ( https://aws.amazon.com/about-aws/whats-new/2020/05/aws-cloudformation-now-supports-blue-green-deployments-for-amazon-ecs/ ) 和 Lambda 函数的蓝/绿部署。

模板的 CodeDeploy 部分如下所示:

Type: AWS::CodeDeploy::DeploymentGroup
Properties:
    DeploymentGroupName: 'SampleGroupName'
    ServiceRoleArn: !Sub 'arn:aws:iam::${AWS::AccountId}:role/AzureDevOps/CodeDeployOperations'
    ApplicationName: !Ref CodeDeployApplication
    AutoScalingGroups:
    - !Ref SampleASG
    DeploymentStyle:
    DeploymentType: BLUE_GREEN
    DeploymentOption: WITH_TRAFFIC_CONTROL
    BlueGreenDeploymentConfiguration:
    TerminateBlueInstancesOnDeploymentSuccess:
        Action: TERMINATE
        TerminationWaitTimeInMinutes: 5
    DeploymentReadyOption:
        ActionOnTimeout: CONTINUE_DEPLOYMENT
    GreenFleetProvisioningOption:
        Action: COPY_AUTO_SCALING_GROUP  
    DeploymentConfigName: !If [IsProdStaging, CodeDeployDefault.HalfAtATime, CodeDeployDefault.AllAtOnce]
    LoadBalancerInfo:
    TargetGroupInfoList:
        - Name: !GetAtt SampleTargetGroup.TargetGroupName
    AutoRollbackConfiguration:
    Enabled: true
    Events:
        - DEPLOYMENT_FAILURE

Answer 1

截至目前(2021 年 10 月)，如果您使用 EC2，AWS 仍然不支持通过 CloudFormation 进行蓝/绿部署。 DeploymentStyle section of the docs 中有一个蓝色注释，阅读:

For blue/green deployments, AWS CloudFormation supports deployments onLambda compute platforms only. You can perform Amazon ECS blue/greendeployments using AWS::CodeDeploy::BlueGreen hook.

令人非常沮丧的是，此功能不可用，因为没有好的解决方法。
