Doc Type: Bug Fix
Doc Text:
Cause: Headless service will have service.Spec.ClusterIP=None and this is not ignored as part of un-idling. Consequence: This will generate incorrect endpoint ID in the HAProxy config and the config will fail to load. This leads to router not servicing any routes. Fix: Ignore headless services during unidle handling Result: No problem with HAProxy config loading and router will service routes as expected.

Description Ravi Sankar 2018-04-24 23:49:46 UTC
+++ This bug was initially created as a clone of Bug #1567532 +++

Description of problem:
An application created from the template "Apache HTTP Server (httpd)" using the example Git repository (and presumably any other application) works fine (readiness probe  and curl on localhost from terminal are both able to access it normally), but when I try to access it via the route (http://testrote-apache-test.193b.starter-ca-central-1.openshiftapps.com/), it shows an error (Application is not available...)

The same thing happens with both HTTP and HTTPS.

Version-Release number of selected component (if applicable):
v3.9.14 (online version 

How reproducible:

Steps to Reproduce:
1. Create a project (and an application) using the "Apache HTTP Server (httpd)" template and the sample repository (https://github.com/openshift/httpd-ex.git).
2. The URL of the generated route is opened in a browser (in my case http://testrote-apache-test.193b.starter-ca-central-1.openshiftapps.com/).

Actual results:
The error "The application is currently not serving requests at this endpoint. It may not have been started or is still starting."

Expected results:
Default OpenShift Apache page.

Tested in atomic-openshift-3.9.27-1.git.0.964617d but still can found error in haproxy logs when creating headless service and idling it.

E0502 06:15:17.588280       1 limiter.go:137] error reloading router: exit status 1
[ALERT] 121/061517 (963) : parsing [/var/lib/haproxy/conf/haproxy.config:229] : 'server ept:service-unsecure:None:27017' : could not resolve address 'None'.

seems the PR has not been merged to 3.9.27.

Comment 9 Ben Bennett 2018-05-03 15:57:38 UTC
3.9.27-1 was cut before this was merged.  Not sure why it got moved by the errata tool.
