How to deploy functions app where name is autogenerated using uniqueString

[elygre]

This is perhaps neither a bug nor a feature request, but more of a "how do I...".

We're deploying the infrastructure for a functions app using bicep, where the name of the functions app itself is generated using the uniqueString function: var functionAppName = 'yggdrasil-${uniqueString(resourceGroup().id)}'. This is deployed using a pipeline in Azure DevOps, which is probably relevant.

Now, we also want to automate the deployment of the app itself. The CLI func azure functionapp publish <funcname> needs to know the function name, which is autogenerated.

I guess there are two questions:

• Is there an obvious solution?
• Is publishing the function app something that might be done from within bicep, using the functionAppName variable -- now or in the future?

Hi @elygre

you can leverage Bicep Outputs for this process, it will involve two stages.

1. output the resource function name from your bicep configuration
2. reading that output and writing it to a AzureDevOps pipleline variable, which can then be consumed by your function app publish command.

you should find some samples of this in this issue.

However if that is missing anything feel free to let us know, also let us know if that works for you.
