[chef] Re: AWS CloudFormation + Chef

[Peter Norton < >]

CloudFormation expects to control all of the resources that you launch with it, so what you're asking for is an ordering of events that it doesn't accommodate.

The specific workflow that you're talking about when you say "bootstrap the instance of an appropriate "Role" and, as the role dependency, launch the CloudFormation Stack (or a relevant part of it, say for security group or/and the keys )" is problematic anyway.  Specifically in AWS your ec2 instance is assigned to a group or list of groups when you request it's creation and before it is allocated.  The assigned group/groups can't be changed once the instance is launched.

Hi All,

I have started to learn about the new AWS tool called CloudFormation.
All seems good and pretty working, however some points are still unclear, here is the one for instance:
- while I see a lot of examples which make use of Chef-Solo (or download cookbook from Chef server) to bootstrap the instance as part of launching the new "Stack" from AWS console ,
I wonder if its possible to use it opposite way: bootstrap the instance of an appropriate "Role" and, as the role dependency, launch the CloudFormation Stack (or a relevant part of it, say for security group or/and the keys ) via Chef, using knife or similar.
... Assuming there should be a Chef helper to interact with AWS CloudFormation API
Does anyone have such usage example ?
