In a recent project, we used Azure Datafactory in a closed network and needed to access resources on-premises. That means that you cannot use the Autoresolve runtime of Datafactory. We thus used our own VM and installed the Self Hosted Integration Runtime software using a VM extension. So far, so good. We needed to install another piece of software on that VM a little later in the project. I started adding another VM extension only to find out that you can only install one VM extension per VM on Azure. We needed to find a way to install multiple dependencies on the VM using a single VM extension in a configurable and manageable way. This blog will describe how we did that using Terraform.
