Packer

Packer is an open-source tool that automates the creation of identical machine images for multiple platforms, such as virtual machines, cloud servers, or containers. It allows developers and IT teams to define configurations once and then generate consistent, ready-to-use images across different environments, streamlining deployment and ensuring uniformity. Packer uses code to specify the setup process, reducing manual effort, minimizing errors, and speeding up the process of preparing infrastructure for software deployment.
