Doc Type: If docs needed, set a value
Doc Text:
When either a certificate within the chain at `serviceaccount/ca.crt` or any of the certificates within the provided truststore file contain a white space after the `BEGIN CERTIFICATE` declaration, the Java keytool rejects the certificate with an error, causing Origin Metrics to fail to start. As a workaround, Origin Metrics will now attempt to remove the spaces before feeding the certificate to the Keytool, but admins should make sure their certificates don't contain such spaces.

Comment 2 Junqi Zhao 2017-10-20 12:53:07 UTC 
Tested with metrics-hawkular-metrics:3.7.0-0.159.0.0
Steps:
1. Add more spaces to the end of "-----BEGIN CERTIFICATE-----" in /etc/origin/master/ca-bundle.crt.
2. Restart server and deploy metrics 3.7 by using image metrics-hawkular-metrics:3.7.0-0.159.0.0 
3. #oc rsh ${HAWKULAR_METRICS_PODS};
   sh-4.2$cat /var/run/secrets/kubernetes.io/serviceaccount/ca.crt

   #oc rsh ${HAWKULAR_CASSANDRA_PODS};
   sh-4.2$cat /var/run/secrets/kubernetes.io/serviceaccount/ca.crt

   #oc rsh ${HEAPSTER_PODS};
   sh-4.2$cat /var/run/secrets/kubernetes.io/serviceaccount/ca.crt

"-----BEGIN CERTIFICATE-----" field don't have spaces in /var/run/secrets/kubernetes.io/serviceaccount/ca.crt of each pod, beside this, the content is thse same with /etc/origin/master/ca-bundle.crt.

4. Sanity testing of Metrics, it works well.
