market-web already has a normal Service. Resolve it from client and count the addresses. Then add a headless Service in front of the same Pods:
sh
kubectl apply -n straits-9r9192 -f - <<EOF
apiVersion: v1
kind: Service
metadata:
name: web-headless
spec:
clusterIP: None
selector:
app: market-web
ports:
- port: 80
EOFResolve web-headless and count again.
