<p>PoolParty has baked in verification for your clouds. This way, you can test if your cloud deployment is working from within the same method used to start the clouds.</p>
<pre><code>
cloud :app_server do
verify do
ping 80
end
end
</code></pre>
<p>This will ping the remote host after everything else in your clouds.rb has run (ToDo: everything for one node or after everything for all nodes?) . If it fails, it will try to reconfigure (ToDo: what specifically is reconfigured or re-tried?) . If the reconfiguration fails again, something is probably wrong your clouds.rb recipe.</p>
<p>Currently, ping is the only verification baked in to PoolParty.</p>
<p>(ToDo: ping uses <span class="caps">ICMP</span> so it has no port; why does the above code have “ping 80”?)</p>
<p>(ToDo: if, in code above, <code>:app_server</code> implies more than one machine, they are all pinged; good to emphasize; and what amount of delay is used to give a machine time to come up? after how long is the instance abandoned )</p>
<p>(ToDo: what about periodic verification for later repair? Should that be distinct from startup verification?)</p>
