Thanks for that.
I had seen this but didn't really understand what it meant.
Having read through it again I still don't!
I'll give it a try tomorrow and see what happens.
As for the warning about scaling up/down then yes, that is a big
concern. That's the whole point of getting automation in place.
So if anyone can shed any light on this then please do so!
Could you explain more about 'an alternative is to create a floating
ip range that uses private non-routable ip addressees'?

Have a look at https://github.com/openshift/openshift-ansible-contrib/blob/master/playbooks/provisioning/openstack/advanced-configuration.md
I think you want openstack_use_bastion: True but I am yet to test
it out so I’d recommend checking the heat template to see if it
does what I think it does.
At the bottom of that advanced page it mentions that in bastion
mode scale up doesn’t work for some reason, so I don’t know if
that matters for you.
Otherwise an alternative is to create a floating ip range that
uses private non-routable ip addressees. That’s what we’re using
in our on-premise OpenStack. But only because we hadn’t discovered
the bastion mode at the time.
Hope that helps.
I hope this
is the right place to ask questions about the
openshift/openshift-ansible-contrib GitHub repo, and
playbooks for installing OpenShift on OpenStack:
If not then please redirect me.
By following the instructions in that link I successfully ran
deployment that involved provisioning the OpenStack servers
deploying OpenShift using the byo config.yaml playbook. But in
it's immediately obvious that this approach is not really
public IP addresses are assigned to every node. It should only
necessary to have public IP addresses for the master and the
infrastructure node hosting the router.
My expectation is that the best way to handle this would be
1. provision the basic openstack networking environment plus a
node from outside the openstack environment
2. from that bastion node provision the nodes that will form
OpenShift cluster and deploy OpenShift to those.
Are there any examples along those lines?
