# Build Immutable Infrastructure with Packer in CI/CD

This guide focuses on the following workflow for building immutable infrastructure. This workflow can be manual or automated and it can be implemented with a variety of technologies. The goal of this guide is to show how this workflow can be fully automated using Packer for building images from a continuous integration/continuous deployment (CI/CD) pipeline.

1. [Build Images using Packer in CI/CD](./build-image-in-cicd.html)
2. [Upload the new image to S3](./upload-images-to-artifact.html) for future deployment or use during development
3. [Create new Terraform Enterprise runs](./triggering-tfe.html) to provision new instances with the images
