Packer

Packer is a command-line utility that enables you to create identical virtual machine images for various platforms without rebuilding from scratch. By defining your machine state once, Packer clones and adapts the image to work seamlessly across different environments like AWS, Azure, VMware, and more. This eliminates version inconsistencies and reduces deployment time, ensuring your infrastructure is reliable and portable. Ideal for DevOps teams, it streamlines continuous integration and delivery pipelines by providing consistent, ready-to-deploy images wherever you need them.
