I would say all configuration templates need to be changed to allow, eg.$ grep http /etc/kolla/cinder-volume/cinder.conf glance_api_servers = http://10.10.10.5:9292 auth_url = http://internal.somedomain.tld:35357 www_authenticate_uri = http://internal.somedomain.tld:5000 auth_url = http://internal.somedomain.tld:35357 auth_endpoint = http://internal.somedomain.tld:5000 to look like: glance_api_servers = http://glance.service.somedomain.consul:9292 auth_url = http://keystone.service.somedomain.consul:35357 www_authenticate_uri = http://keystone.service.somedomain.consul:5000 auth_url = http://keystone.service.somedomain.consul:35357 auth_endpoint = http://keystone.service.somedomain.consul:5000The idea with Consul looks interesting. But I don't get your issue with VIP address and spine-leaf network. What we have: - controller1 behind leaf1 A/B pair with MLAG - controller2 behind leaf2 A/B pair with MLAG - controller3 behind leaf3 A/B pair with MLAG The VIP address is active on one controller server.When the server fail then the VIP will move to another controller server.Where do you see a SPOF in this configuration?So leaf1 2 and 3 have to share the same L2 domain, right (in IPv4 network)?Yes, they share L2 domain but we have ARP and ND suppression enabled.It is an EVPN network where there is a L3 with VxLANs between leafs and spines.So we don't care where a server is connected. It can be connected to any leaf.
Ok that sounds very interesting. Is it possible to share some internals? Which switch vendor/model do you use? How does you IP address schema look like? If VxLAN is used between spine and leafs are you using VxLAN networking for Openstack as well? Where is your VTEP?
But we wanna deploy a layer3 spine-leaf network were every leaf is it's own L2 domain and everything above is layer3.eg: leaf1 = 10.1.1.0/24 leaf2 = 10.1.2.0/24 leaf2 = 10.1.3.0/24 So a VIP like, eg. 10.1.1.10 could only exist in leaf1In my opinion it's a very constrained environment, I don't like the idea.
