Chef Notes

Fast Start Guide

When doing an amazon node, the hostname is set to an approximation of the IP address. You can specify your node name in client.rb.

node_name "new-name"

If you happened to have already ran chef-client, you can not rename your client but you can delete and recreate it. Do this as early as possible.
