Migration d'un modèle CloudFormation CodeDeploy blue/green deployment template to an Amazon ECS blue/green CloudFormation
Migrez un CloudFormation modèle qui utilise une stratégie CodeDeploy blue/green deployments for Amazon ECS services to one that uses the native Amazon ECS blue/green de déploiement. La migration suit l'approche « Réutilisez les mêmes ressources Elastic Load Balancing utilisées pour CodeDeploy ». Pour de plus amples informations, veuillez consulter Migrer les CodeDeploy blue/green deployments to Amazon ECS blue/green déploiements.
Modèle source.
Ce modèle utilise la AWS::CodeDeployBlueGreen transformation et le AWS::CodeDeploy::BlueGreen hook pour implémenter blue/green des déploiements pour un service Amazon ECS.
Il s'agit du CloudFormation modèle complet utilisant le déploiement CodeDeploy bleu/vert. Pour plus d'informations, consultez l'exemple de modèle de déploiement bleu/vert dans le guide de l' AWS CloudFormation utilisateur :

Étapes de la migration
Supprimer des CodeDeploy ressources spécifiques
Vous n’avez plus besoin des propriétés suivantes :
-
La transformation
AWS::CodeDeployBlueGreen -
Le hook
CodeDeployBlueGreenHook -
Les ressources
GreenTaskDefinitionetGreenTaskSet(elles seront gérées par Amazon ECS) -
La ressource
PrimaryTaskSet(Amazon ECS gérera les jeux de tâches en interne)
Reconfigurer l’écouteur de l’équilibreur de charge
Modifiez la ressource ALBListenerProdTraffic pour utiliser une action directe avec deux groupes cibles :
{ "DefaultActions": [ { "Type": "forward", "ForwardConfig": { "TargetGroups": [ { "TargetGroupArn": {"Ref": "ALBTargetGroupBlue"}, "Weight": 1 }, { "TargetGroupArn": {"Ref": "ALBTargetGroupGreen"}, "Weight": 0 } ] } } ] }
Mise à jour des propriétés de déploiement
Mettez à jour et ajoutez les éléments suivants :
-
Modifiez la propriété
DeploymentControlleren remplaçantEXTERNALparECS. -
Ajoutez la propriété
Strategyet définissez-la sur BLUE_GREEN. -
Ajoutez de la propriété
BakeTimeInMinutes.{ "DeploymentConfiguration": { "MaximumPercent": 200, "MinimumHealthyPercent": 100, "DeploymentCircuitBreaker": { "Enable": true, "Rollback": true }, "BakeTimeInMinutes": 5, "Strategy": "BLUE_GREEN" } } -
Ajoutez la configuration de l’équilibreur de charge au service :
{ "LoadBalancers": [ { "ContainerName": "DemoApp", "ContainerPort": 80, "TargetGroupArn": {"Ref": "ALBTargetGroupBlue"}, "AdvancedConfiguration": { "AlternateTargetGroupArn": {"Ref": "ALBTargetGroupGreen"}, "ProductionListenerRule": {"Ref": "ALBListenerProdRule"}, "RoleArn": {"Fn::GetAtt": ["ECSInfrastructureRoleForLoadBalancers", "Arn"]} } } ] } -
Ajoutez la référence de définition de tâche au service :
{ "TaskDefinition": {"Ref": "BlueTaskDefinition"} }
Création du ECSInfrastructure RolePolicyForLoadBalancers rôle Amazon
Ajoutez un nouveau rôle IAM qui permet à Amazon ECS de gérer les ressources de l'équilibreur de charge. Pour de plus amples informations, consultez Rôle IAM d’infrastructure Amazon ECS pour les équilibreurs de charge.
Recommandations de test
-
Déployez le modèle migré dans un environnement hors production.
-
Vérifiez que le service se déploie correctement avec la configuration initiale.
-
Testez un déploiement en mettant à jour la définition de la tâche et en observant le processus de déploiement bleu/vert.
-
Vérifiez que le trafic est correctement transféré entre les déploiements bleu et vert.
-
Testez la fonctionnalité de restauration en forçant un échec de déploiement.
