@anoopl, thing is, I'm not using the Helm chart thingy, I applied manually the YAMLs under /manifest folder to my cluster, and I can't see that vaules.yaml file aywhere... :-(

@dnaranjor You will have values.yaml only when you install it with Helm.
This configs should be some where else in manifest, I am not sure, have not tried the manual installation

great! was so helpful :-)
