# Exemple de modèle de déploiement bleu/vert
L'exemple de modèle suivant configure un déploiement CodeDeploy bleu/vert sur ECS, avec une progression du routage du trafic de 15 % par étape et une période de stabilisation de 5 minutes entre chaque étape.
La création d’une pile à partir de ce modèle configure la configuration initiale du déploiement. Si vous apportez ensuite des modifications aux propriétés de la `BlueTaskSet` ressource qui nécessitent son remplacement, vous CloudFormation lancerez un déploiement écologique dans le cadre de la mise à jour de la pile.
