Packer

Packer automates the creation of machine images that are consistent across different infrastructure environments. Using a simple configuration file, it builds images for cloud providers, on-premises servers, and containers from the same source. This guarantees that your development, staging, and production setups are identical, minimizing deployment issues. It integrates with provisioning tools like Ansible and Chef, supports parallel builds, and is ideal for DevOps workflows seeking efficiency and repeatability.
