Teardown and Cleanup

Reverse-provisioning teardown order

Section titled “Reverse-provisioning teardown order”
  1. Cleanup API and hosting surfaces first ( AMPLIFY
    AWS Amplify — hosts the walkthrough dashboard frontend and connects it to the query API URL.     and API Gateway
    Amazon API Gateway — exposes HTTP routes for latest telemetry and recent events. The browser reads data through API Gateway, not DynamoDB directly.     workflow)
  2. Destroy TERRAFORM
    HashiCorp Terraform — provisions shared infrastructure (IoT rules fan-out, Lambda, DynamoDB, API Gateway, Amplify).     -managed infrastructure
  3. Deprovision device credentials and IoT Core
    AWS IoT Core — managed MQTT broker with X.509 device authentication for ESP32 telemetry and events.     registration

Terraform destroy

Section titled “Terraform destroy”
Terminal window
terraform -chdir=terraform destroy

Device deprovisioning

Section titled “Device deprovisioning”

Full teardown (device + CloudFormation stack):

Terminal window
FORCE=1 REMOVE_LOCAL=1 AWS_REGION=ap-southeast-2 THING_NAME=esp32-c ./aws/deprovision.sh

Partial cleanup:

Terminal window
# Device only — keep Phase 1 CloudFormation stack
FORCE=1 DEVICE_ONLY=1 AWS_REGION=ap-southeast-2 THING_NAME=esp32-c ./aws/deprovision.sh


# Shared infra only — delete stack esp32-demo-phase1; keep Thing/certs
FORCE=1 INFRA_ONLY=1 AWS_REGION=ap-southeast-2 ./aws/deprovision.sh

FORCE=1 is required — the script deletes AWS resources.
