aws = db[ node.chef_environment][‘aws’]
AWS_ACCESS_KEY_ID = aws[‘AWS_ACCESS_KEY_ID’]
AWS_SECRET_ACCESS_KEY = aws[‘AWS_SECRET_ACCESS_KEY’]

aws_resource_tag node[‘ec2’][‘instance_id’] do
aws_access_key aws[‘AWS_ACCESS_KEY_ID’]
aws_secret_access_key aws[‘AWS_SECRET_ACCESS_KEY’]
tags({“Name” => “Monitor”,
“node_name” => “#{node.name}”,
“environment” => node.chef_environment})

Your error is in this line. Most likely node['ec2'] is nil, so node['ec2']['instance_id'] evaluates to nil['instance_id'] which causes the error.

If you're using EC2 VPC, the cause of your problem is likely this: http://tickets.opscode.com/browse/OHAI-310

Try touching this file: /etc/chef/ohai/hints/ec2.json

But I am not using VPC.

Also..looking at hosted chef..I do not see ec2 attribute..yet I am using
ec2? Did ohai fail? I though chef would auto detect ec2.....

Hi David,

Are you absolutely certain? If you started using a region in the last few
months, you'll automatically be creating instances in a VPC (see
http://aws.typepad.com/aws/2013/03/amazon-ec2-update-virtual-private-clouds-for-everyone.html
)

Also..looking at hosted chef..I do not see ec2 attribute..yet I am using
ec2? Did ohai fail? I though chef would auto detect ec2.....

Daniel's suggestion (creating the ohai hint) is the best thing to try.
Does it fix your problem?
If so, the problem is that Ohai cannot automatically detect that you are
running on EC2. Creating the hint file is the correct way to fix that.

This is what we use in our EC2/VPC bootstrap script

mkdir -p /etc/chef/ohai/hints && touch /etc/chef/ohai/hints/ec2.json
