Packer: The Magic Tool You Didn’t Know You Needed

Packer: The Magic Tool You Didn’t Know You Needed If you’ve ever tried setting up a server or deploying applications manually, you know the pain—it’s like assembling IKEA furniture without the instructions. Enter Packer, a tool that makes creating machine images easy, efficient, and—dare I say—almost fun. So, What is Packer? Packer, created by HashiCorp, is an open-source tool designed to automate the creation of machine images. These images can be used in AWS, Azure, Google Cloud, VirtualBox, VMware, and more. Instead of clicking through a million settings manually, Packer lets you define your infrastructure as code. Think of it as meal prepping but for your servers. You set up everything once, store the perfect recipe, and reuse it whenever you need.
