Zipkin Cleanup

Since TSB 1.6, Zipkin Backend was replaced by OAP, and after the upgrade, Zipkin-related components and resources should be manually cleaned up.

The following zipkin items need to be cleared after the upgrade:

Clean up Zipkin in the control plane​

note

Do not delete zipkin service, it is now served by the OAP deployment.

kubectl -n ${CONTROL_NAMESPACE} delete deployment zipkin
kubectl -n ${CONTROL_NAMESPACE} delete configmap  zipkin-envoy-config
kubectl -n ${CONTROL_NAMESPACE} delete secret zipkin-token
kubectl -n ${CONTROL_NAMESPACE} delete secret zipkin-envoy-rds-config
kubectl -n ${CONTROL_NAMESPACE} delete serviceaccount zipkin
kubectl -n ${CONTROL_NAMESPACE} delete horizontalpodautoscaler zipkin --ignore-not-found

kubectl -n ${MANAGEMENT_NAMESPACE} delete deployment zipkin
