[chef] Re: How to handle the elastic_ip associate recipe to finish up smoothly?

["Scott M. Likens" < >]

Hi,

Unfortunately if you are not running chef-solo under (screen and/or tmux) your SSH connection will get interrupted once the new IP address is attached to the instance. 

The only real way to make this better is to either do one of the following:

1. Run chef-client under screen/tmux on the server itself.   Likely modifying the bootstrap so it installs screen (and or tmux) and then runs chef-client under that. 
   
2. Provision the servers first and then run knife bootstrap once the Elastic IP address is attached.
• ec2-run-instances ami-.... then follow up with ec2-associate-addresses to the instance.

I hope that helps.

Hi Chefellas!

I fire up a ec2 instance on AWS as follows:

    knife ec2 server create -E staging -N cf-worker -x ubuntu -G cf-worker -i
~/.ssh/deployer.pem -r 'role[resque_worker]'

    .....

base, base::sshd, aws, base::iptables, users::sysadmins, cf_users,
cf_worker::default, cf_worker::deploy, cf_worker::resque,
cf_worker::associate_eip]
    .....

The last recipe cf_worker::associate_eip in the run_list is as follows:


    if node.has_key?("cloud")
      include_recipe "aws"

      aws = data_bag_item("aws", "main")
      elastic_ips = data_bag_item("aws", "elastic_ips")

      eip = elastic_ips['cf_worker'][node.chef_environment]

      aws_elastic_ip "eip_cf_worker" do
	aws_access_key aws['aws_access_key_id']
	aws_secret_access_key aws['aws_secret_access_key']
	ip eip
	action :associate
      end
    end

If I exclude this last recipe, everything goes smoothly and well and the
chef-handler completes successfully.
But If I include it, doesn't matter the order, whether I put it at first or
middle or last, the moment it associates the Elastic Ip, it keeps on hanging.

Its so weird and I couldn't figure out why this happens?
How you guys handle the elastic ip scenerio?
