Teardown¶
Remove Everything¶
1. Delete KNative resources¶
kubectl delete broker default -n default
kubectl delete ksvc hello-knative event-display -n default
kubectl delete trigger event-display-trigger -n default
2. Destroy Azure infrastructure¶
This removes:
- AKS cluster (and all workloads)
- Event Hubs namespace and hub
- Virtual Network
- Resource Group
Data Loss
terraform destroy is irreversible. All events in Event Hubs and workloads in AKS will be permanently deleted.
Partial Cleanup¶
Remove just KNative (keep AKS + Event Hubs)¶
# Remove Kafka components
kubectl delete -f "https://github.com/knative-extensions/eventing-kafka-broker/releases/download/knative-v1.22.1/eventing-kafka-broker.yaml"
# Remove KNative Eventing
kubectl delete -f "https://github.com/knative/eventing/releases/download/knative-v1.22.1/eventing-core.yaml"
kubectl delete -f "https://github.com/knative/eventing/releases/download/knative-v1.22.1/eventing-crds.yaml"
# Remove Kourier
kubectl delete -f "https://github.com/knative/net-kourier/releases/download/knative-v1.22.1/kourier.yaml"
# Remove KNative Serving
kubectl delete -f "https://github.com/knative/serving/releases/download/knative-v1.22.1/serving-core.yaml"
kubectl delete -f "https://github.com/knative/serving/releases/download/knative-v1.22.1/serving-crds.yaml"
Remove just Event Hubs (keep AKS + KNative)¶
cd terraform
terraform destroy -target=azurerm_eventhub_consumer_group.knative \
-target=azurerm_eventhub_authorization_rule.knative_listen \
-target=azurerm_eventhub_authorization_rule.knative_send \
-target=azurerm_eventhub.knative \
-target=azurerm_eventhub_namespace.main
Cost Awareness¶
| Resource | Approximate Monthly Cost |
|---|---|
| AKS (2× D4s_v5) | ~$280 |
| Event Hubs (Standard, 1 TU) | ~$11 |
| Public IP (Kourier LB) | ~$4 |
| Total | ~$295/month |
