AWS AMI Cleanup
This gem provides the cleanup_amis
script that allows deregistering unused AMIs. The IAM user running the command must have at the very least the following permissions:
- ec2:DescribeImages
- ec2:DescribeLaunchTemplateVersions
- ec2:DescribeInstances
- ec2:DeregisterImage
- ec2:DeleteSnapshot
- autoscaling:DescribeAutoScalingGroups
Script should be invoked as follows:
cleanup_amis clean_amis --ami_name 'my-ami' --ami_owner 'self'
Where ami_owner
can be a combination of AWS account IDs, self
, amazon
, and aws-marketplace
.
Additionally you can provide the number_of_amis_to_keep
argument to specify how many AMIs to keep (default is 3) and region
for the AWS region (default is us-east-1
).
