🔰 Description

This command-line tool allows you to determine, given an AMI in a specific AWS region, its associated AMIs in the other AWS regions. This is especially useful for developers writing CloudFormation templates deploying EC2 instances that require to create mappings of AMIs for the different regions which the CloudFormation template supports.

This application allows you to create AMI mappings automatically using :

• A base AMI (e.g ami-0de53d8956e8dcf80) in a given AWS region.
• A base AMI name (e.g amzn2-ami-hvm-2.0.20190313-x86_64-gp2) in a given AWS region.

🛠 Usage

Generate an AMI mapping given a base AMI

In order to generate a mapping of AMIs given a base AMI associated with an AWS region, you can run the following command.

ami-resolver --region us-east-1 --output yaml --ami ami-0de53d8956e8dcf80

Here, the base AMI ami-0de53d8956e8dcf80 associated with the region us-east-1 is known, and passing it to ami-resolver will generate the the AMI mapping for all the AWS regions.

Generate an AMI mapping given a base AMI name

In order to generate a mapping of AMIs given an AMI name associated with an AWS region, you can run the following command.

ami-resolver --region us-east-1 --output yaml --ami-name amzn2-ami-hvm-2.0.20190313-x86_64-gp2

Here, the AMI name amzn2-ami-hvm-2.0.20190313-x86_64-gp2 associated with the region us-east-1 is known, and passing it to ami-resolver will generate the the AMI mapping for all the AWS regions.

Changing the mapping output

The ami-resolver command-line tool supports different ways to output the AMI mapping :

• Json - Creates a CloudFormation compatible AMI mapping in the JSON format.
• Yaml - Creates a CloudFormation compatible AMI mapping in the YAML format.
• Text - Creates a textual output of the AMI mapping (this is the default choice when the --output option is not specified).
