Packer
A tool for creating identical machine images for multiple platforms from a single source configuration.
What is Packer?
Packer is an open-source tool developed by HashiCorp that automates the creation of identical machine images for multiple platforms from a single source configuration. It solves the problem of environment inconsistency by enabling infrastructure-as-code practices for image building across cloud providers, virtualization platforms, and container systems. Packer ensures that development, staging, and production environments are reproducible and consistent.
DevOps engineers, system administrators, and platform teams who need to create consistent machine images across multiple cloud providers and virtualization platforms. It's particularly valuable for organizations practicing infrastructure-as-code and continuous delivery.
Developers choose Packer because it provides a unified workflow for building machine images across all major platforms, eliminates environment drift through reproducible builds, and integrates seamlessly with other HashiCorp tools like Vagrant and Terraform. Its plugin architecture and parallel execution make it both extensible and performant.
