Teardown

When the lab session is complete, destroy all Azure resources to stop billing.

Terraform Destroy

From the directory containing the Terraform configuration:

# Review what will be destroyed
terraform plan -destroy

# Destroy all resources
terraform destroy

Terraform will prompt for confirmation. Type yes to proceed.

Verify Cleanup

Confirm all resources have been removed:

# Check resource group is gone
az group show --name "$(terraform output -raw resource_group_name)" 2>&1 \
  | grep -q "ResourceGroupNotFound" \
  && echo "Resource group deleted" \
  || echo "Resource group still exists"

Clean Up Local State

Remove Terraform state and cached files:

rm -rf .terraform .terraform.lock.hcl terraform.tfstate terraform.tfstate.backup

Revert DNS/Hosts Changes

If you modified DNS or hosts files during integration, revert those changes:

# Remove hosts file entry (Linux/macOS)
sudo sed -i '/<CDN_EDGE_PUBLIC_IP>/d' /etc/hosts

If you created a DNS A record, delete it through your DNS provider.
