The<br> plug-in runs on the client, not the server, and basically allows you to<br> use shell scripts that talk to your cloud, and have Juju call those when<br> it needs to do things like start a new machine. The machines are started<br> by your shell script, then Juju remotely logs in to the machine and<br> "manually" configures it.

So for each cloud you just need to know what<br> the "blank" machine image is for the OS versions your charms will use.<br> IN future we might support creating snapshots which can be reused for<br> faster startup of additional machines.<br> <br> Does that answer your question?<br> <span><font color="#888888"><br> Mark<br> <br> </font></span></blockquote></div><br></div></div></div> <br></div></div><span><font color="#888888">--<br> Juju mailing list<br> <a href="mailto:Juju@lists.ubuntu.com" target="_blank">Juju@lists.ubuntu.com</a><br> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/juju" target="_blank">https://lists.ubuntu.com/mailman/listinfo/juju</a><br> <br></font></span></blockquote></div><br></div></div> </blockquote></div><br></div></div></div> </blockquote></div></div></div><br></div></div> </blockquote></div><br></div></div>
