Debugging curtin from within MAAS

Deploying a node with MAAS cli

You can deploy a node with the maas cli which is often preferable to clicking a button on a web UI.

$ SYSTEM_ID=node-787b19d8-d25c-11e4-9f9e-00163eca91de
$ NAME="random-nodename"
$ MAASNAME="maaslocal"

$ maas $MAASNAME machine allocate "name=$NAME"

What

A lot of times you are developing a web application on your own laptop or home computer and would like to demo it to the public. Most of those times you are behind a router/firewall and you don't have a public IP address. Instead of configuring routers (often not possible), this solution gives you a public URL that's reverse tunnelled via ssh to your laptop.

Because of the relaxation of the sshd setup, it's best used on a dedicated virtual machine just for this (an Amazon micro instance for example).
