Hi, You can done it simple by updating your new public url network ip address under endpoint table of keystone db.If you are -using domain name instead of ip address,you can map the new public ip corresponding to that domain name in domain management portal.In my case,I entered my public endpoint name in /etc/hosts file for the sake of simplicity. For example,

Then modify the neutron,nova conf file where it needs your public url.

To verify the whether changes has been reflected or not by using the following command.

export your openstack credentials to your shell environment.

$ sudo source admin-rc.sh

$ sudo openstack endpoint list

$ sudo openstack endpoint show <endpoint id="">

or

$ sudo nova endpoints

You will get the output like this for all registered services via keystone.

Thanks and regards,
