Packer is a HashiCorp tool for building automated machine images from a single source template. It helps teams create consistent images for multiple platforms, including cloud providers and Docker, supporting repeatable infrastructure workflows and the creation of golden images for image pipelines. HashiCorp provides Packer documentation, installation guidance, tutorials, and integration resources to help users get started and develop their skills. The documentation covers key topics such as templates, which describe how images should be built, and the Packer command-line interface and its workflows.

For organizations managing images across cloud providers, HCP Packer offers build-management capabilities and tools to manage machine images across an organization. HashiCorp also provides practical tutorials focused on image pipelines, artifact version revocation, and compliance. Examples show how Packer can work alongside Terraform and HCP Terraform to build application images, provision infrastructure, and identify or prevent the use of revoked, outdated, hard-coded, or untracked image artifacts. Users can also connect with the Packer community through forums, user groups, and live office hours.
