Setup Azure Function Hybrid Connection

In this latest post in Donnie and I’s Migrating from Orchestrator series, I’ll show you how to setup Hybrid Connection for PowerShell Azure Functions. This will allow you to perform automation tasks on-prem with Function Apps using PowerShell Core.

Requirements

  • App Service Plan
  • Azure Function in my case I’m using PowerShell Core

You’ll need a non shared or dev/test App Service Plan. The cheapest one I’m aware of that allows Hybrid Connections is the B1 which is the Basic plan. https://azure.microsoft.com/en-us/pricing/details/app-service/windows/

Otherwise Hybrid Connections won’t show up, if using a Consumption Function. Or if you’re on a shared or dev/test App Service Plan you’ll get this message.

Give your connection a name, a end point name that can be resolved on the server Hybrid connections will be isntalled on. Then give it a port to use, and Servicebus topic.

In my case because I selected port 777. I did have to make a special firewall rule for TCP 777 before the connection was successful.
