Multi-Provider Support
Packer supports a wide variety of providers such as AWS, Azure, Google Cloud, VMware, and more. This allows for flexibility and the ability to create machine images across different environments.
Automation
Packer automates the creation of machine images, eliminating the need for manual image configuration and reducing the potential for human error.
Script Reusability
Packer allows for the reuse of scripts and configuration files, enabling a consistent and repeatable process for image creation.
Parallel Builds
Packer can build multiple images in parallel, which can significantly speed up the provisioning process.
Idempotency
Packer ensures that the output machine image is always an identical result given the same input configuration, reducing the risk of inconsistencies.
If you have just upgraded to Ubuntu 22.04, and you suddenly experience either errors when trying to ssh into hosts, or when running ansible or again when running the ansible provisioner building a packer image, this is probably going to be useful for you.

I am already using Hashicorp Packer at work and for personal projects and I wanted to test
This idea out by wrapping it a single Packer Template file. This reduces the level of maintaining
a lot of small scripts, Dockerfiles and configurations and the user can simply trigger a couple of
Commands to get a minimalist OS at the end of the process.

And while it is a slight increase in complexity, it can be an overall net gain in functionality, configurability and reliability. Much like Packer is far more reliable and practical than manually making VM images sitting in front of a terminal, even though making the initial configuration takes some time.

Hashicorp Packer provides a nice wrapper / abstraction over the QEMU in order to boot the image and use it to set it up on first-boot.
Instead of writing really long commands in order to boot up the image using QEMU, Packer provided a nice Configuration Template in a more
Readable fashion.

Packer seemed like the perfect tool for the job.
I have never used it before and wanted to get familiar with the tool.
It doesn’t come with ARM support out of the box, but there are two community projects to fill that niche.

Packer is an Open Source tool that can be used to create identical images for different platforms, what it makes the process of creation and deployment of your infrastructure to be simple, as it uses a single configuration file.

I just want to add a quick reference to Packer, as it’s just great to be able to apply the same convenience to VMs too~.

You’re going to want to use packer for that, specifically built for this purpose.

Packer is an open source tool developed by Hashicorp for automating the creation of any type of machine image. You can use it for creating a custom Vagrant box for your development environment. That’s what I will cover on this article.
