Open Stack

Thank you!  I am trying the path of adding a separate physical (although its really virtual..) network that will be exclusively for lb-mgmt….that would work also, correct?  I added a port to my virtual router and the added a corresponding port to each openstack vm.  It sounds like only control and compute nodes need it but I was going to add it to everything to start and then eliminate one by one once it worked.

Would that approach also work?

Subject: Re: Octavia
The stacktrace shows that Octavia can't reach an Amphora. I suppose you get this log when trying to create a loadbalancer? If so, most likely the Amphora management network is not set up correctly.

The difficulty is that Octavia workers, which are processes running on the controllers, need to have access to the same management network as the Amphora instances. If you implement the management network as a normal tenant network, some non-trivial manual Openvswitch configuration is required. See https://docs.openstack.org/octavia/latest/install/install-ubuntu.html#install-and-configure-components for instructions. In production settings, usually a VLAN is used, which is easy to access from controller processes.

I succeeded running Octavia on a Kolla cluster with three-way controllers, with a tenant network (VXLAN-based) for amphora management. My notes are attached (they are tailored to my configuration, of course).

Bernd.

Well…it gets. A lot further….  I see this error now…. Im looking around to see if it’s a security group missing or if there is some other setting I missed.  Im not seeing any scripts to prep the env…usually there is something like that if it’s a security group…anyone know?
