AWS EC2 Image Builder is a service for building AMIs and Docker images using defined recipes.
It is managed by AWS and can be accessed via the AWS Console.
Infrastructure as Code best practice recommends defining Image Builder recipes using tools like CloudFormation or Terraform.
The Image Builder process involves selecting a base image, setting up Infrastructure Configuration, and using the AWS Systems Manager Agent for executing commands.
Components are YAML documents containing steps like installing software and validating configurations.
Creating components involves defining build, validate, and test phases using YAML.
Terraform can be used to load components and create them, with examples provided in the article.
Recipe, infrastructure, and distribution configurations are essential parts in Image Builder.
Pipelines, which execute recipes on infrastructure and distribute new images, can be scheduled with AWS Image Builder.
The article also covers creating instances using the built images and accessing them via the browser on specific ports.
