Uninstall an ACK Controller
Use the helm uninstall command to uninstall an ACK service controller:
export SERVICE=s3
# Uninstall the ACK service controller with Helm
helm uninstall -n $ACK_SYSTEM_NAMESPACE ack-$SERVICE-controller
Delete CRDs
Delete individual CRDS
If you have multiple controllers installed and only want to delete CRDs related to a specific resource, use the kubectl delete command to delete the CRDs with the the service name prefix.
For example, use the following commands to delete the CRD for Amazon S3 Buckets:
export SERVICE=s3
export CHART_EXPORT_PATH=/tmp/chart
# Delete an individual CRD
kubectl delete -f $CHART_EXPORT_PATH/$SERVICE-chart/crds/s3.services.k8s.aws_buckets.yaml
Check for CRDs that are common across services
There are a few custom resource definitions (CRDs) that are common across services. If you have multiple controllers installed, you should not delete the common CRDs unless you are uninstalling all of the controllers.
Delete all CRDs
If you are sure that you would like to delete all CRDs, use the following commands:
export SERVICE=s3
export CHART_EXPORT_PATH=/tmp/chart
# Delete all CRDs
kubectl delete -f $CHART_EXPORT_PATH/$SERVICE-chart/crds
Verify Helm charts were deleted
Verify that the Helm chart for your ACK service controller was deleted with the following command:
helm ls -n $ACK_SYSTEM_NAMESPACE
Delete namespaces
Delete a specified namespace with the kubectl delete namespace command:
kubectl delete namespace $ACK_SYSTEM_NAMESPACE
Delete ConfigMap
If you used cross account resource management, delete the ConfigMap you created.
kubectl delete -n ack-system configmap ack-role-account-map
