Packer is easy to use and automates the creation of any type of machine image. It embraces modern configuration management by encouraging you to use automated scripts to install and configure the software within your Packer-made images. Packer brings machine images into the modern age, unlocking untapped potential and opening new opportunities.
Out of the box Packer comes with support to build images for Amazon EC2, DigitalOcean, Docker, Google Compute Engine, QEMU, VirtualBox, VMware, Microsoft Azure, and more. Support for more platforms is on the way, and anyone can add new platforms via plugins.
