Add binding to Key Vault

Functions often need password, API keys, and connection strings to connect to other services and retrieve data. It would be great if those secrets could easily be obtained from Key Vault.

Hi all,

Thank you all for the comments and feedback. We’re very pleased to announce that support for Key Vault references is now generally available! You can find the update here: https://azure.microsoft.com/updates/general-availability-of-key-vault-references-in-app-service-and-azure-functions/

The work certainly doesn’t stop here. We are looking to add support for additional networking configurations, and work is underway for rotation handling (making the version string optional). Please consider putting votes towards these features as well! They are captured below.

Rotation: https://feedback.azure.com/forums/169385/suggestions/36532414

Firewall/ServiceEndpoints: https://feedback.azure.com/forums/355860/suggestions/38817385

Again, thanks for all of the input on this item. It really does make a difference.

- Matthew

Hi all,

We’re pleased to announce a public preview of our Key Vault references feature, which you can learn more about here: https://azure.microsoft.com/en-us/blog/simplifying-security-for-serverless-and-web-apps-with-azure-functions-and-app-service/

There are some limitations to the initial preview, but we’re hoping to address those very soon. We’re looking forward to your feedback!

Thank you,
Matthew, Azure Functions team

Hi all,

This will be available this calendar year.

I want to clarify that it is not planned as a separate binding, but rather as a core capability that applies to all bindings. This means that all secrets used for binding configuration (and any others, too) can be sourced from Key Vault. The design involves the app setting value being a reference to a secret in Key Vault, so all you would need to do is make a change to App Settings. The platform will use the managed identity of the application to resolve the secret and make it available to code. The initial release will require secret versions to be explicitly defined, but we are hoping to develop automatic rotation semantics for future updates.

Thanks to everyone for all of the active discussion here. We understand this is an incredibly important and long-anticipated feature, and we’re really looking forward to getting it into your hands soon.

This is a good idea. We’ll look at this later when we’re ready to start adding more bindings (likely after we GA).

Has this been implemented by any chance. All clients want to maintain their security information in Key Vault

Can't use Functions without this. This is an absolute must. ETA?

Any updates here? My customer requires all connection strings be stored in KeyVault and this is a problem for using functions.

Add this binding and Azure Function usage will hit an all new high! It would be great not to have to re-store the secrets in the App Config.

Any idea when this might become available? I really need it. The cert approach didn't get approved by IT Security.

A necessary feature, and overall great idea. Examples of securables are tokens (like Github, Slack) and certificates.

This would be great.

Food for thought, this recent development in .NET Core might reduce the amount of custom code you need for this.

I believe I read somewhere that this had basically been accepted and if so, this is just a ping to update status here.

There is no feature in azure functions to azure key vault integration for Trigger and Outputs connection strings.

Please suggest any alternative solutions for this feature.
