Custom Compnents

Components are used by Image Builder Recipes in order to setup the software envrioment.

In short, a component installs sofware for an AMI.

Developers can either choose to preset components, use components shared by others, or create their own custom components

List all custom componenets

aws imagebuilder list-components

Get component info

When you have the desired ARN (for the specific component and version) from above command, you can get the info of the component using the following command

aws imagebuilder get-component --component-build-version-arn ${ARN}

Component configuration

In particualr, it is important to be able to get the yaml configuration associated to a particular component/version

aws imagebuilder get-component --query component.data  --component-build-version-arn ${ARN}  --output text

An exmaple of a yaml configuration for a component can be seen below.

The component

• will update packages installed by yum package manager
• download docker
• download docoker-compose (using default version - else calling receipe can specify a version)
• ensure docker is started as a service - ensures it stays up when users logoff
