Descrpition

TCP DNS Server doesn't accept requests over TCP from client pod in Istio and Istio Booking example. It also rejects TCP DNS requests from other pods on the same node of cluster.

Error from neighbour pod

dig @10.244.1.76 productpage.default.svc.cluster.local +tcp
;; communications error to 10.244.1.76#53: connection reset

Steps to reproduce

  1. Run Istio-booking example
  2. Go to cluster2
  3. Install dig on autoscale-endpoint using apk add bind-tools
  4. Run dig @NSE_POD_IP productpage.default.svc.cluster.local +tcp
  5. Look at result of request

NSE_POD_IP means pod ip of cmd-nse-l7-proxy on cluster2
