I am working on setting up Openstack for HA and one of the last orders of business is getting HA behavior out of the compute nodes.
There is no HA behaviour for compute nodes.
Is there a project that will automatically evacuate instances from a downed or failed compute host, and automatically reboot them on their new host?
Check out Masakari: https://wiki.openstack.org/wiki/Masakari
I'm curious what suggestions people have about this, or whatever advice you might have. Is there a best way of getting this functionality, or anything else I should be aware of?
You are referring to HA of workloads running on compute nodes, not HA of compute nodes themselves.
My advice would be to install Kubernetes on one or more VMs (with the VMs acting as Kubernetes nodes) and use that project's excellent orchestrator for daemonsets/statefulsets which is essentially the use case you are describing.
The OpenStack Compute API (implemented in Nova) is not an orchestration API. It's a low-level infrastructure API for executing basic actions on compute resources.
