Eine Vorlage migrieren CloudFormation CodeDeploy blue/green deployment template to an Amazon ECS blue/green CloudFormation
Migrieren Sie eine CloudFormation Vorlage, die eine CodeDeploy blue/green deployments for Amazon ECS services to one that uses the native Amazon ECS blue/green Bereitstellungsstrategie verwendet. Die Migration folgt dem Ansatz „Dieselben Elastic Load Balancing Balancing-Ressourcen wiederverwenden, für die sie verwendet wurden CodeDeploy“. Weitere Informationen finden Sie unter Bereitstellungen migrieren CodeDeploy blue/green deployments to Amazon ECS blue/green.
Quellvorlage
Diese Vorlage verwendet AWS::CodeDeployBlueGreen Transform und AWS::CodeDeploy::BlueGreen Hook, um blue/green Bereitstellungen für einen Amazon ECS-Service zu implementieren.
Dies ist die vollständige CloudFormation Vorlage mit CodeDeploy Blau/Grün-Einsatz. Weitere Informationen finden Sie im AWS CloudFormation Benutzerhandbuch unter Beispiel für eine blaue/grüne Bereitstellungsvorlage:

Schritte zur Migration
CodeDeploy-spezifische Ressourcen entfernen
Sie benötigen die folgenden Eigenschaften nicht mehr:
-
AWS::CodeDeployBlueGreen-Transformation -
CodeDeployBlueGreenHook-Hook -
GreenTaskDefinition- undGreenTaskSet-Ressourcen (diese werden von Amazon ECS verwaltet) -
PrimaryTaskSet-Ressource (Amazon ECS verwaltet Aufgabensätze intern)
Neukonfiguration des Load Balancer-Listener
Ändern Sie die ALBListenerProdTraffic-Ressource so, dass sie eine Weiterleitungsaktion mit zwei Zielgruppen verwendet:
{ "DefaultActions": [ { "Type": "forward", "ForwardConfig": { "TargetGroups": [ { "TargetGroupArn": {"Ref": "ALBTargetGroupBlue"}, "Weight": 1 }, { "TargetGroupArn": {"Ref": "ALBTargetGroupGreen"}, "Weight": 0 } ] } } ] }
Bereitstellungseigenschaften aktualisieren
Folgendes aktualisieren und hinzufügen:
-
Ändern Sie die Eigenschaft
DeploymentControllervonEXTERNALaufECS. -
Fügen Sie die
Strategy-Eigenschaft hinzu und setzen Sie sie auf BLUE_GREEN. -
Fügen Sie die
BakeTimeInMinutes-Eigenschaft hinzu.{ "DeploymentConfiguration": { "MaximumPercent": 200, "MinimumHealthyPercent": 100, "DeploymentCircuitBreaker": { "Enable": true, "Rollback": true }, "BakeTimeInMinutes": 5, "Strategy": "BLUE_GREEN" } } -
Fügen Sie dem Service die Load-Balancer-Konfiguration hinzu:
{ "LoadBalancers": [ { "ContainerName": "DemoApp", "ContainerPort": 80, "TargetGroupArn": {"Ref": "ALBTargetGroupBlue"}, "AdvancedConfiguration": { "AlternateTargetGroupArn": {"Ref": "ALBTargetGroupGreen"}, "ProductionListenerRule": {"Ref": "ALBListenerProdRule"}, "RoleArn": {"Fn::GetAtt": ["ECSInfrastructureRoleForLoadBalancers", "Arn"]} } } ] } -
Fügen Sie dem Service die Referenz zur Aufgabendefinition hinzu:
{ "TaskDefinition": {"Ref": "BlueTaskDefinition"} }
Erstellen Sie die ECSInfrastructure RolePolicyForLoadBalancers Amazon-Rolle
Fügen Sie eine neue IAM-Rolle hinzu, die es Amazon ECS ermöglicht, Load Balancer-Ressourcen zu verwalten. Weitere Informationen finden Sie unter Amazon-ECS-IAM-Infrastrukturrolle für Load Balancer.
Testen von Empfehlungen
-
Stellen Sie die migrierte Vorlage in einer Nicht-Produktionsumgebung bereit.
-
Stellen Sie sicher, dass der Service mit der Erstkonfiguration korrekt bereitgestellt wird.
-
Testen Sie eine Bereitstellung, indem Sie die Aufgabendefinition aktualisieren und den Blau/Grün-Bereitstellungsprozess beobachten.
-
Stellen Sie sicher, dass der Datenverkehr korrekt zwischen den blauen und grünen Bereitstellungen wechselt.
-
Testen Sie die Rollback-Funktion, indem Sie einen Bereitstellungsfehler erzwingen.
