使用ruby和aws-sdk来拉取ec2标签

Question

Folks, I am trying to pull in the EC2 tags via ruby aws-sdk and iam roles. The following bit of code produces error below. What am I doing wrong?

require 'rubygems'
require 'aws-sdk'
require 'fileutils'

ec2 = AWS::EC2.new()

instance_id = `wget -q -O - http://169.254.169.254/latest/meta-data/instance-id`
outdir = '/opt/facts/tags/'

unless File.directory?(outdir)
  FileUtils.mkdir_p(outdir)
end

ec2= AWS::EC2.new()
instance = ec2.instances[instance_id]
tags = instance.tags

tags.each do |num|
  File.open(outdir+num[0], "w") do |f|
    f.write(num[1])
  end
end

Following output:

Answer 1

That seems to be a bug that was already reported today: undefined method `continue_timeout=' , you could try pointing to the main branch of the git repository since there's already a patch for it.

Edit:

You can already point the latest version in rubygems since they already deployed the fix on version 1.9.1 : https://rubygems.org/gems/aws-sdk

There was a bug announced today in AWS-SDK-ruby https://github.com/aws/aws-sdk-ruby/issues/232

You can fix it by updating your gemfile

gem 'aws-sdk', "1.9.1"

And then running "bundle"
