In the ever-evolving landscape of DevOps, the concept of immutable infrastructure is gaining significant traction, promising more reliable, scalable, and simpler management processes. Immutable infrastructure is a model where servers are never modified after they’re deployed; instead, new servers are built from a common image with all the necessary configurations and software pre-installed, and deployed to replace older ones. For Linux Bash users, Packer by HashiCorp offers a powerful platform to create these server images reproducibly and manage infrastructure as code. Here’s a detailed guide on how to harness Packer in creating immutable infrastructure setups for your system.

In the world of software development and IT operations, automating repetitive tasks is key to efficiency and reliability. One area ripe for automation is the creation of virtual machine (VM) images. Whether you're deploying to a cloud platform or managing a virtualized environment on premises, creating consistent, repeatable VM images is crucial. This is where Packer by HashiCorp becomes an invaluable tool. In this blog post, we'll explore what Packer is, its benefits, and how you can get started with it on Linux using Bash, including installation instructions for different Linux distributions. Packer is an open-source tool designed for creating identical machine images for multiple platforms from a single source configuration.
