I'm trying to use OpenStack in what I think to be the typical non-public-cloud deployment, and my experience is not what it could/should be. I'm hoping someone can point me to the "right way", or we can figure out what needs to change.
My wishlist: * I want my instances to be on "my network" e.g. 10.0.0.0/16 * As Nova can't pull IPs from my DHCP server, I'm willing to allocate it a sub-range, e.g. 10.200.0.0/16 First decision: Choosing a networking mode: * I don't want / need VLANs * If I use FlatDHCPManager, I can't do the subrange stuff - it seems that this mode assumes it controls the entire address range. * So it's FlatManager. It works, but now I don't have DHCP, so I just have to inject info into the instance. Next decision: How to inject info (at least the IP address): * Supposedly the 'right way' is to use cloud-init. It looks like I'd still need DHCP before I can reach 169.254..., and I don't have that. It looks like cloud-init can't do network configuration even if nova passed the information in. And I'd be locked into cloud-init images - no Windows, no Debian etc. * The next best way is config_drive. It looks like I'd have to bundle my own image. Maybe I could use cloud-init, maybe with an OVF formatted config_drive, but even then I couldn't configure networking (?) * So now I'm back to file injection. That just works. So now I'm using FlatManager and file injection; and yet I feel this is the dodgy back alley of OpenStack, and I should be in the well-lit nice area. I worry that things like file injection and FlatManager are less favored and may be deprecated in future. But every time I try to do things "right" I just waste a lot of time and make no progress. Yet I feel I didn't really have a choice here. How are other people making this work? What is the "right way"?
