linux - Chef Recipe ArgumentError 未知指令 : "\n"

Question

我正在使用 chef-server 11 并使用 chef-provisioning gem 来自动化云基础架构。 我有一个从 AMI 创建实例的简单方法，但它失败了 ArgumentError 未知指令:“\n”错误

我的 Chef Recipe 是

require 'chef/provisioning/aws_driver'
with_driver 'aws::us-east-1'
machine 'new-chef-instance' 
do 
   machine_options :ssh_username => 'root',
       :bootstrap_options => 
        {
         :key_name => 'mykeyname',
         :image_id => 'myamiid',
         :instance_type => 't2.micro',
         :subnet_id => 'mysubnetid',
         :security_group_ids => 'my-security-group' 
        }
end

像这样执行这个 Recipe 之后

chef-client -z recipes/createserver.rb

创建实例后出现以下错误

[2015-08-24T11:42:17+00:00] INFO: Processing chef_node[new-chef-provision] action create (basic_chef_client::block line 57)

虽然实例已正确创建并且我可以从命令行对其进行 SSH，但完整的配方执行失败，我该如何修复错误并且我确定我的配方中没有额外的字符“\n”

Answer 1

在创建 machine 资源和开始其 block 的 do 之间有一个额外的换行符。
