cloud-nuke

Cloud-nuke is a command-line interface tool designed to delete AWS resources in bulk for account cleanup and cost management purposes. The tool provides both destructive and non-destructive functionality, allowing users to either inspect resources or delete them entirely. It supports cleaning up testing accounts, removing redundant resources, and eliminating unnecessary default configurations such as default VPCs and permissive security group rules. The tool can be used as a standalone CLI application or consumed as library methods for scripting purposes. It offers comprehensive support for various AWS services including EC2 instances, Auto Scaling groups, Elastic Load Balancers (v1 and v2), EBS volumes, AMIs, snapshots, Elastic IPs, and launch configurations. Additional supported resources include EC2 IPAM components (IP Address Manager, pools, scopes, custom allocations, BYOASN, and resource discovery), networking components (Internet Gateways, Network ACLs, egress-only internet gateways, endpoints), and security components (security groups and network interfaces). The tool is particularly useful for preventing unexpected charges from leftover resources in testing environments and maintaining clean AWS accounts by removing unused or default resources.
