Question

I'm playing around with Chef to launch EC2 instances. Everything is working pretty well, but Chef doesn't seem to have the ability to tag the instances. Am I missing something?

Otherwise, what's the preferred Ruby library for achieving this? Can I do it without requiring additional gems?

Thanks

Was it helpful?

Solution

Version 0.5.12 of the knife-ec2 Gem supports tagging EC2 instances on creation with the --tags option.

knife ec2 server create [... your options...] --tags Tag=Value

OTHER TIPS

Know this is old, but was browsing about and spotted it. Another alternative is to use the AWS community cookbook - assuming you have key creds - if you want to do things programatically as part of the recipe.

aws = data_bag_item('mydatabag', 'creds')
aws_resource_tag node['ec2']['instance_id'] do
  aws_access_key aws['access_key']
  aws_secret_access_key aws['secret_key']
  tags({
    "foo" => "bar"
  })
  action :update
end

Usually chef is used to install things on the instance. I'm not exactly sure how you start a node with chef, but maybe you can share this and I'll extend my answer?

Otherwise, fog is a great library to do these things. I just skimmed over the source and it seems to support tagging as well.

To get fog: gem install fog.
