If you're on 0.25.x or higher, you can absolutely load balance, as the masters are no longer significantly stateful. It's just like any web server. There's nothing special you have to do as far as Puppet is concerned apart from working out how to write your health monitors. We run curl locally on the masters and export the health such that the load balancers can inspect it. If you're on 0.24.x, you can't do this if you're using environments without somehow sharing the state directory amongst masters. > > > > Thanks for your time. > > > > > > -- > You received this message because you are subscribed to the Google Groups > "Puppet Users" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]. > For more options, visit this group at > http://groups.google.com/group/puppet-users?hl=en. > -- nigel -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
