Description Eric Rich 2018-03-28 19:58:14 UTC
Description of problem: when we enable this optional wildcard route: It takes precedence over other routes, rendering them unreachable, but we have noticed that it only overrides routes starting with a number.

Version-Release number of selected component (if applicable): kubernetes v1.6.1+5115d708d7

How reproducible: 100%

Steps to Reproduce:
1. https://gist.github.com/jmprusi/929ab4ffdf6dcda14dde704184421e80

curl service1. -> hits service1
curl random. -> hits route-wildcard, this is expected.
curl service2. -> hits service2
curl 3service127.0.0.1.nip.io -> hits route-wildcard, this is NOT expected

Verified this bug on v3.10.0-0.47.0


1. enable the wildcard for router
  oc env dc router ROUTER_ALLOW_WILDCARD_ROUTES=true

2. Create one app with wildcard route
  $oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/routing/wildcard_route/caddy-docker.json
 $oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/routing/wildcard_route/route_edge.json
 $oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/routing/wildcard_route/route_unsecure_test.example.com.json

3. Create another app with route with number prefix
  oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/routing/header-test/dc.json
oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/routing/header-test/insecure-service.json
 oc expose svc header-test-insecure --hostname=32zhao.test.example.com --name=zhao

4. Check the route 32zhao.test.example.com
 curl --resolve 32zhao.test.example.com:80: http://32zhao.test.example.com
  user-agent: curl/7.29.0
  accept: */*
  host: 32zhao.test.example.com
  x-forwarded-host: 32zhao.test.example.com
  x-forwarded-port: 80
  x-forwarded-proto: http
  forwarded: for=;host=32zhao.test.example.com;proto=http

5. Check the wildcard route 
# curl --resolve zhao.test.example.com:80: http://zhao.test.example.com
Hello-OpenShift-1 http-8080
