This is a repackaged open source software product wherein additional charges apply for support. Packer is a powerful, open-source tool designed by HashiCorp to streamline the process of creating machine images for multiple platforms in a consistent and automated manner. By using a single source configuration, Packer can generate images for various environments such as Amazon Web Services, Google Cloud Platform, Microsoft Azure, VirtualBox, Docker, and more. This ensures that the images are identical and that deployment is predictable and repeatable, reducing the risk of configuration drift and simplifying the process of managing infrastructure as code. Packer integrates seamlessly with existing tools and workflows, making it a valuable addition to the DevOps toolkit for building and maintaining portable and reproducible environments.
