When using Foreman/Puppet is it possible for multiple instances to share
the same back end database?
Reason I'm asking this I'm considering how to set up multiple puppet
masters and use a load balancer to route traffic to the "closest" master
using a multicast VIP. If there are multiple databases I'm concerned that
things will get out of sync.
or am I over thinking this?
You can share the same database with Foreman just fine, it's the usual
way to implement a cluster for scaling.
I'd suggest adding a memcached instance and adding the foreman_memcache
plugin too, which Foreman will use for a shared internal cache among all
of your instances. Otherwise you'll have per-host caches which could
get out of sync.
