Puppet HA: Proof-of-Concept
vagrant up and wait. Puppet clients
agent* will be provisioned
last. If all goes well, then they will run
puppet agent -t once against
any master via DNS round-robin and then once against each available master,
individually. All three runs should succeed.
Now you can start shutting down instances of gluster, puppet or puppetdb. Reinstallation of instances should also work for agent, puppet and puppetdb.
If you don't have the time or a powerful enough development machine, have
a look at the file output.txt. It contains the output of the
shell provisioner for a successful run of
vagrant up | egrep 'Machine booted
and ready|Running provisioner|^[+]'.
We still need to work on a way to add/remove/reinstall gluster nodes and a high-availability/load-balancing setup for PostgreSQL (master plus hot-standby). The latter task is tracked in issue #1.
