Azure Key Vault – securing configuration with custom health checks
In this recipe, we’ll integrate Azure Key Vault to securely store and manage sensitive configuration data, such as API keys. Rather than hardcoding credentials in appsettings.json, we’ll use Key Vault to centralize our secrets, accessing them directly from Azure when needed.
Since calls to Key Vault can slightly slow down local development, we’ll also configure the .NET user-secrets tool to store secrets locally. This is a preferred approach, as it keeps sensitive data out of appsettings.json and reduces the risk of accidentally exposing secrets in source control.
To ensure our app can reliably access Key Vault in production, we’ll implement custom health checks that monitor connectivity. These checks provide real-time alerts if Key Vault becomes unreachable, preventing us from scratching our heads wondering why we cannot authenticate.
Like the previous recipe, we will use...
