+# Image Builder
+
+AWS service automating the creation, management, and deployment of customized AMIs or Docker images.
+
+1. [TL;DR](#tldr)
+1. [Further readings](#further-readings)
+ 1. [Sources](#sources)
+
+## TL;DR
+
+Images created by Image Builder in one's account are owned by that account.
+
+Leverages AWS' Task Orchestrator and Executor component management application.
+For AMIs, it:
+
+1. Creates EC2 instances for building and validation.
+1. Creates a snapshots of the result.
+1. Terminates the EC2 instances used for building.
+1. Uses that snapshot to create new EC2 instances for testing.
+
+For containers, it:
+
+1. Creates EC2 instances for building and validation.
+1. Builds container images.
+1. Runs containers from the images for testing.
+1. Terminates the EC2 instances used for building.
+
+
+ Glossary
+
+| Term | Summary |
+| ---------------------------- | ----------------------------------------------------------------------------------------------- |
+| Component | YAML-based document defining the steps to take to build, validate or test images |
+| Recipe | Document defining the base image and the components to apply to it to produce the desired image |
+| Infrastructure Configuration | The EC2 infrastructure to use to build and test the desired image |
+| Distribution Configuration | How the outputted images are made available to specified AWS Regions |
+| Pipeline | Automation framework for creating and maintaining custom images |

+| CentOS | 7, 8 |
+| CentOS Stream | 8 |
+| Mac OS X | 12.x (Monterey), 13.x (Ventura), 14.x (Sonoma) |
+| Red Hat Enterprise Linux (RHEL) | 7, 8, 9 |
+| SUSE Linux Enterprise Server (SLE) | 12, 15 |

+
+
+
+Image Builder costs **nothing** to create custom AMI or container images per se.
+However, standard pricing applies for the other services that are used by or in the process, like EC2 instances, EBS
+volumes, and ECR storage.
+
+Components can be specified **at most once** in an image recipe.
+
+Steps:
+
+
+ AMI creation
+
+1. \[optional] Create new _components_ as needed.
+1. \[optional] Create a new image _recipe_.
+1. \[optional] Create a new _infrastructure configuration_.
+1. \[optional] Create a new _distribution configuration_.
+1. Create a new _pipeline_.
