Packer
Packer is a machine image build tool and multi-platform image orchestrator. It functions as an infrastructure as code image builder that produces identical machine images across multiple platforms from a single source configuration to ensure environment consistency.
The tool enables the creation of a golden image pipeline by generating compatible system images for different cloud providers and on-premises hypervisors. It includes an image lifecycle registry to store metadata for tracking the versioning and status of generated images.
The system manages the automation of machine image creation and deployment. It supports parallel build execution to generate multiple images across different platforms simultaneously and utilizes a plugin-based provider interface to abstract platform-specific API calls.
Features
- Virtual Machine Image Packaging - Packages pre-configured virtual machine disk images for consistent deployment across multiple platforms.
- Infrastructure as Code - Defines and automates the creation of machine images using a declarative code-based approach.
- Golden Image Automation - Implements an automated workflow to create standardized golden images for environment replication.
- Image Synthesis - Provides a mechanism for creating machine images based on a sequenced set of build instructions.
- OCI Virtual Machine Image Management - Produces identical machine images for multiple platforms from a single configuration to ensure environment consistency.
- Multi-Platform Image Orchestration - Orchestrates the creation and delivery of compatible system images across various cloud providers.
- Image Builders - Uses a declarative approach to define and produce machine images to ensure consistency across deployments.
- Multi-Platform Image Creation - Generates identical virtual machine images for diverse cloud platforms and hypervisors from a single source.
- Virtual Machine Image Construction - Builds bootable disk images and runner scripts from a system specification to create identical machine images.
- Cloud Provider Abstractions - Decouples the core build logic from underlying cloud APIs using a standardized driver layer.
