19/30 - Terraform Provisioners (with demo) - local vs remote vs file

Welcome back to day 19 of our Terraform series! In this video, I'll walk you through the complexities and power of Terraform Provisioners. While Terraform is designed primarily for infrastructure management, there are scenarios where you need to bootstrap instances or run specific scripts immediately after creation. This video dives deep into the three main types of provisioners: `local-exec`, `remote-exec`, and the `file` provisioner. We will discuss how to execute commands on your host machine versus the target resource and how to securely transfer files during the build process. We will also address the important "last resort" philosophy—explaining why HashiCorp recommends using these sparingly compared to configuration management tools like Ansible or user data scripts. What you'll learn in this video: The core differences between local-exec, remote-exec, and file provisioners. How to set up connection blocks and handle SSH keys for remote execution. A hands-on demo provisioning an AWS EC2 instance and bootstrapping it with a web server. Best practices for error handling and failure behavior in provisioners.
