用于创建、加固并分发云环境标准化虚拟机镜像的自动化工具与流水线。
Packer is a machine image builder and multi-platform image orchestrator used to create identical virtual machine images for multiple platforms from a single source configuration. It functions as an infrastructure as code tool, utilizing the HashiCorp Configuration Language to define versioned and reproducible templates for cloud image provisioners. The tool is distinguished by its plugin-based extension model, which allows it to load external binaries for builders and provisioners to support various cloud platforms and virtualization environments. It includes a post-processor pipeline to tran
Packer is the industry-standard tool for building identical virtual machine images across multiple cloud platforms using declarative templates, with built-in provisioners and post-processors that cover the full pipeline from base image to hardened, versioned artifacts — exactly what this immutable infrastructure workflow needs.
