[chef] Re: Attach an ec2 instance on the existing ELB

[Joshua Timberman < >]

Ohai,

What is the goal here? Are you trying to set up something for autoscaling? Or 
are you just looking to register new nodes with an ELB?

If you're doing autoscaling, I'd consider building a custom AMI for the nodes 
that need to autoscale. I'd make that with the validation.pem and JSON with 
the run list for the nodes you want, and also sets up chef-client to run at 
launch or as a service.

If you just want to add nodes to an ELB, Opscode's "aws" cookbook has an 
elastic_lb resource, which you could use in your own cookbook. I'd assign the 
ELB name as an attribute in the role for the node's in the role you want to 
use, and then reference that attribute in the resource.

    aws_elastic_lb 'my-load-balancer' do
      name node['aws']['load_balancer']
      aws_access_key aws['aws_access_key_id']
      aws_secret_access_key aws['aws_secret_access_key']
    end
