Creating reusable modules with Bicep, Terraform or Pulumi

Sun, 12 Mar 2023 00:00:00 +0000

Over the years, I’ve been working with several infrastructure as code tools. One of the things that I always find essential, no matter the tool, is to write readable and maintainable code. One way to do that is to create a proper structure for what you are building. All of the IaC tools I have used allow you to modularize your code somehow. A module is a piece of code responsible for one specific thing.

Installing multiple VM extensions on an Azure VM using Terraform

Sat, 25 Feb 2023 00:00:00 +0000

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.

Custom Domain on Azure App Service using Terraform and Cloudflare

The other day, I was building some infrastructure on Azure that contained an Azure App Service. I wanted to use a custom domain so that users can use the application over a nice domain name instead of the *.azurewebsites.net. The infrastructure is built using Terraform; luckily, there is a provider for Cloudflare. Cloudflare is where the domain’s DNS is managed. This blog post will walk you through the steps to do all the configuration.

Terraform Azure DevOps to Azure example pipeline

I finally had the opportunity to work with Terraform on one of my recent projects. I have been building Infrastructure as Code with ARM templates or Bicep for years. Together with two friends, I even wrote a book on that! Terraform was always on my list of tools to work with. I had played around with it a little in my spare time but never got the opportunity to put it to use in an actual project. This blog will help you get started!
