Hi lejeczek, What you are describing is what a load balancer provides. The load balancing project for OpenStack is Octavia. We have a cookbook that can guide you through setting up a load balancer: https://docs.openstack.org/octavia/latest/user/guides/basic-cookbook.html We also gave an OpenStack summit presentation that is an introduction to load balancing: https://youtu.be/BBgP3_qhJ00 Load balancers provide the health monitoring and automatic redirection of network traffic. They can also provide this failover much faster than reconfiguring a floating IP. Michael On Thu, Jul 23, 2020 at 11:56 AM lejeczek <peljasz@yahoo.co.uk> wrote:
hi guys,
A novice here so go easy on me please. I wonder - is there a mechanism in openstack, a built-in feature where a floating IP could be juggled between guests/instances dynamically - would you know? What comes to mind is something like HA/pacemaker, something where business logic operates around condition and actions. I cannot make is simpler than such an example - instance_A has floating_IPa but if something "bad" happens to it then floating_IPa moves to instance_B - can something like that be handled by openstack's tooling or goes outside its realm and can only be worked out however anybody would do it individually?
many thanks, L.
