In questo esempio vengono creati un segreto e un'istanza Amazon DocumentDB che utilizzano le credenziali nel segreto come utente e password. Il segreto ha una policy basata sulle risorse collegata che definisce chi può accedere al segreto. Il modello, inoltre, crea una funzione di rotazione Lambda e configura il segreto da Modelli di funzione di rotazione affinché ruoti automaticamente tra le 8:00 e le 10:00 UTC il primo giorno di ogni mese. Come best practice di sicurezza, l'istanza si trova in un Amazon VPC.
Questo esempio utilizza le seguenti CloudFormation risorse per Secrets Manager:
