Esempio di modello di implementazione blu/verde
Il modello di esempio seguente configura una distribuzione CodeDeploy blu/verde su ECS, con un avanzamento del routing del traffico del 15% per fase e un periodo di stabilizzazione di 5 minuti tra ogni passaggio.
La creazione di uno stack con il modello prevede il provisioning della configurazione iniziale dell’implementazione. Se in seguito sono state apportate modifiche alle proprietà della BlueTaskSet risorsa che richiedono la sostituzione di tale risorsa, CloudFormation verrà avviata una distribuzione ecologica come parte dell'aggiornamento dello stack.
