A new platform for documentation and tutorials is launching soon.
We are migrating Packer documentation into HashiCorp Developer, our new developer experience.
Packer is an open source tool that enables you to create identical machine images for multiple platforms from a single source template. A common use case is creating "golden images" that teams across an organization can use in cloud infrastructure.
To install Packer and learn the standard Packer workflow, try the Get Started tutorials.
The HCP Packer registry bridges the gap between image factories and image deployments, allowing development and security teams to work together to create, manage, and consume images in a centralized way.
The HCP Packer registry stores metadata about your images, including when they were created, where the image exists in the cloud, and what (if any) git commit is associated with your image build. You can use the registry to track information about the golden images your Packer builds produce, clearly designate which images are appropriate for test and production environments, and query for the right golden images to use in both Packer and Terraform configurations.
