Esempio di modello di implementazione blu/verde
Il modello di esempio seguente imposta una distribuzione CodeDeploy blu/verde attivaECS, 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 fornirà la configurazione iniziale della distribuzione. Se in seguito sono state apportate modifiche alle proprietà della BlueTaskSet risorsa che richiedono la sostituzione di tale risorsa, CloudFormation avvierà una distribuzione ecologica come parte dell'aggiornamento dello stack.
