Destroy Containerlab Stack

Tears down everything created by Deploy Containerlab Stack — destroys the running containerlab topology, then deletes the EC2 hypervisor and related AWS resources (VPC, subnet, security group, keypair). Topology teardown is best-effort so hypervisor cleanup still runs if the instance is already gone.

Prerequisites

• A stack previously deployed with NETWORK ǀ Deploy Containerlab Stack
• AWS credential configured

Survey prompts

Prompt	Variable	Type	Required
AWS Region	clab_aws_region	multiplechoice	Yes

Options: us-east-2, us-west-2 — use the same region as Deploy.

1. Teardown Topology — Runs containerlab destroy on the hypervisor (skipped cleanly if no hypervisor is found)
2. Teardown Hypervisor — Always runs next: terminates the EC2 instance and removes VPC, subnet, security group, and keypair

Job templates

Template	Playbook	Description
NETWORK ǀ Destroy Containerlab Stack	network/setup.yml	Workflow that tears down topology then AWS resources
NETWORK ǀ Containerlab ǀ Teardown Topology	network/teardown_containerlab.yml	Destroys the running containerlab topology
NETWORK ǀ Containerlab ǀ Teardown Hypervisor	network/teardown_hypervisor.yml	Deletes the EC2 hypervisor and related AWS resources

Presenter walkthrough

1. When to use: End of a demo session or when you need a clean rebuild. Safe to run if topology teardown is a no-op.
2. Launch: Select the same AWS region used for Deploy.
3. Watch always_nodes: Topology teardown feeds hypervisor teardown on the always path so AWS cleanup is not skipped.
