Comment 2 Junqi Zhao 2017-07-10 02:12:19 UTC 
Verify step is the same as 
https://bugzilla.redhat.com/show_bug.cgi?id=1447463#c64

Verification steps:
1. Add the example certificate before and after /etc/origin/master/ca-bundle.crt.
2. Restart server and deploy metrics 3.5 by using images from brew registry.
3. oc rsh ${HAWKULAR_METRICS_PODS};
   cat /var/run/secrets/kubernetes.io/serviceaccount/ca.crt

/var/run/secrets/kubernetes.io/serviceaccount/ca.crt is the same with /etc/origin/master/ca-bundle.crt.

4. Login web console, metrics can  be viewed, see the attached web UI snapshot

Testing env:
# openshift version
openshift v3.5.5.31
kubernetes v1.5.2+43a9be4
etcd 3.1.0

Imags from brew registry, metrics-hawkular-metrics latest image version is 3.5.0-25

Same verification steps as Comment 2, login web console, metrics can  be viewed, Hawkular Metrics can handle connecting to the Kubernetes Master when the ca.crt contains multiple certificates now.

Testing env:
# openshift version
openshift v3.5.5.31.6
kubernetes v1.5.2+43a9be4
etcd 3.1.0
