I would like to fix this with

1. predeployment step which uploads dump file to storage
2. postdeployment step which restores db from storage - perhaps an Azure Function so there isn't anything locally happening in terms of permissions/secrets
3. postdeployment test to validate that resource group has no security alerts (@nitya fyi)

1. Internal sub security threat thrown on deployment for Azure function because deployment logs contain secrets
2. Azure Function has the following deployment input params
   • AZURE_COSMOS_CONNECTION_STRING_KEY connection string to get to user, payment, reservations.
   • STRAPI_DATABASE_PASSWORD to get to Strapi
   • AzureWebJobsStorage for any trigger work

Working on this still.
