Re: [ceph-users] Ceph on Public IP

Hello John,
Thank you for the clarification. I am using Google cloud platform for this
setup and I don't think I can assign a public ip directly to an interface
there. Hence the question.

Thanks

[ceph-users] Ceph on Public IP

[nithish B]

Hi all,
I am installing ceph using ceph-deploy. I am installing it on 4 VMs which
have private IP addresses and public IPs NAT-ted to it. But upon
installation, even after adding

public network = 0.0.0.0/0

it still listens on the private IP.
I tried doing the steps mentioned in http://docs.ceph.com/docs/
master/rados/configuration/network-config-ref/  but I still face the issue.

Any directions in this regard will be helpful.

Thanks & Regards,
Nitish B.
