add public ip / dns to node data (ec2)

[wrightp]

This likely applies to other cloud platforms, but the urgent need is specific to ec2.

Once the instances are launched and the public IPs (and DNS if available) are generated it would be really useful if the local node data for those instances get updated with the information.

Not sure if the capability is there now, and must be called explicitly, but perhaps it makes sense for this to be the default behavior.

This works for me. I launch my nodes in ec2 with options to request a public IP. I also provide the ohai hint for ec2 and then the information is available in the cloud (and presumably ec2) node data. For exmaple, I get the assigned IP address using node[:cloud][:public_ipv4]. The key is to provide the ec2 hint to ohai if you are not already doing so.

Awesome! Trying this now. Thanks for the info.

@Patrick-Wright did that fix it?

Now that ec2 hints are part of chef-metal, this is fixed.
