Consider that you need to create multiple instances of a particular resource using Terraform. How do you go about it? You may think of declaring multiple resource blocks, using a for_each loop or exploring a third option that’s probably the best bet. Yes, I’m talking about the Terraform count meta-argument. Read more…
As infrastructure evolves, it becomes more complex. Technically, you can describe the complete infrastructure of an application in a single Terraform file. But eventually, you will run into issues such as: Terraform modules are the most-effective way to avoid the above issues and reduce the complexity of your infrastructure code. Read more…
It is always more tempting to use Terraform to provision shining, brand-new infrastructure. However, many times you need to tone down your expectations and work with existing infrastructure for various organizational reasons. The question is – can you manage an existing AWS EC2 instance or any other resource using Terraform? Read more…
Do you want to target multiple resources in your Terraform configuration code? If yes, your best bet is to use the powerful combination of Terraform data source and for_each looping. While data sources in Terraform allow you to create dynamic infrastructure, the for_each keyword helps you extend the flexibility to Read more…
You must have heard about Nginx. If not, here’s a quick reference: Nginx is a webserver. But it can wear many hats. You can use it as a reverse proxy, a load balancer and even as an HTTP cache. Websites expecting high traffic often rely on Nginx because of its Read more…
I will start off this post with a simple statement and then try to show you why this statement is absolutely true. Here it goes: Terraform Conditional Data Source is the key to building flexible infrastructure. And yes, I’m talking about conditional data source. Of course, Terraform Data Source is Read more…
Terraform works great with static configuration code to provision infrastructure. However, most real-world deployments need to be dynamic and depend on external data. Terraform Data Source is a must-have ingredient to provision resources dynamically. In this post, you get to learn everything about Terraform Data Sources with code examples. 1 Read more…
