Uninstallation and Cleanup

To remove the Anonymization service and all associated Kubernetes and AWS resources:

1. Uninstall the Helm release

# Removes all chart resources. PVC data is RETAINED by default (retentionPolicy: whenDeleted=Retain).
helm uninstall anonymization -n anon-ns

# To also delete the database PVC:
kubectl delete pvc -n anon-ns -l app.kubernetes.io/name=anonymization

Optionally, delete the namespace after the Helm release and PVCs are removed using the following command:

kubectl delete namespace anon-ns

2. Destroy OpenTofu infrastructure

Warning: tofu destroy deletes the S3 bucket, including all stored input and output datasets. Back up any data you need before proceeding.

# Destroys the Karpenter nodes, IAM role, Pod Identity association, and S3 bucket.
tofu destroy -var="cluster_name=<CLUSTER_NAME>"

Note: By default, tofu destroy prompts for confirmation before deleting resources. Add -auto-approve to skip the prompt.
