Test running a cloud-init userdata file
<p>A cloud-config userdata file looks great for initialization, but how can you iteratively go about developing and testing it?</p>

<p>The feedback delay is just too high if you need to provision instances every time until you get everything right.</p>

<p>Assume a toy instance in AWS or equivalent with a userdata <em>file</em>, how can I run have cloud-init run it manually, after boot?</p>
