Cloudify on openstack without an External network

[Ben Haines]

Hi,

I'm using cloudify 3.0 (via pip) on our internal openstack deployment. The bootstrapping ("cfy bootsrap") process is failing because the external network (ext_network) in our openstack deployment isn't truly external. Meaning it uses RFC1918 address space and as such has the "external network" flag set to no.

Exception occurred in provider: 400-{u'NeutronError': {u'message': u'Bad router request: Network 07b42e97-7b03-48f6-8a6c-6d7cfdb3240a is not a valid external network', u'type': u'BadRequest', u'detail': u''}}

I can avoid the Router error (above) being thrown by creating a router, but it then simply fails for the same reason trying to secure a floating IP.

Exception occurred in provider: 400-{u'NeutronError': {u'message': u'Bad floatingip request: Network 07b42e97-7b03-48f6-8a6c-6d7cfdb3240a is not a valid external network', u'type': u'BadRequest', u'detail': u''}}

Does anybody have any thoughts on how I can overcome this issue? Unfortunately I don't know the codebase well enough yet to hack the code.

If it helps, our internal openstack deployment has a single large network called 'public' with RFC1918 addressing. Connections outbound to the Internet are routed via a squid proxy and inbound connections via a VIP/NAT managed separately outside of openstack.

Thanks for your help/comments in advance.

With the help of some colleagues I've solved this issue.

There is actually another openstack network we use for floating IPs, using this as the external network and defining a separate admin network allows the bootstrap process to continue for a bit longer.

Please guide :)

Hi Ankur,

I think your comment is intended for the Openstack support forum and not Cloudify since you are only using the Neutron CLI.
