Doc Type:	Bug Fix
Doc Text:	Cause: Python image was overly restrictive about allowing host connections by default Consequence: Readiness probes would fail because they could not connect from localhost. Fix: Change the defaults to allow connections from any host, including localhost. Result: Readiness probe will be able to connect from localhost and the readiness probe will succeed.

Description Siva Reddy 2016-11-02 12:04:35 EDT

Created attachment 1216615 [details]
The logs for pod showing the readiness probe fail

Description of problem:
   The django psql quick start template app doesn't install and fails the readiness probe

Version-Release number of selected component (if applicable):
openshift v3.4.0.18+ada983f
kubernetes v1.4.0+776c994
etcd 3.1.0-rc.0

How reproducible:
always

Steps to Reproduce:
1. Create a new project and a new app in it using quick start template
    oc new-project django
    oc new-app --template=django-psql-example
2. Wait for the pods to come up and note the state of the django app pod

Actual results:
    The pod goes into crashloopBackoff after failing the readiness probe

Expected results:
    the pod should come up and should be in running state

Additional info:
    The logs for the pod are attached. It looks like the pod_ip:8080/health is failing.
