Knife 设置

为了设置 Knife，需要转到 .chef 目录并在 chef repo 中创建一个 knife.rb，该文件会告诉 Knife 有关配置的详细信息。这将包含一些详细信息。

current_dir = File.dirname(__FILE__) 
log_level                :info 
log_location             STDOUT 
node_name                'node_name' 
client_key               "#{current_dir}/USER.pem" 
validation_client_name   'ORG_NAME-validator' 
validation_key           "#{current_dir}/ORGANIZATION-validator.pem" 
chef_server_url          'https://api.chef.io/organizations/ORG_NAME' 
cache_type               'BasicFile' 
cache_options( :path =>  "#{ENV['HOME']}/.chef/checksums" ) 
cookbook_path            ["#{current_dir}/../cookbooks"]

在上面的代码中，我们使用托管的 Chef 服务器，它使用以下两个键。

validation_client_name   'ORG_NAME-validator' 
validation_key           "#{current_dir}/ORGANIZATION-validator.pem"

在这里，knife.rb 告诉 knife 使用哪个组织以及在哪里找到私钥。它告诉 knife 在哪里找到用户的私钥。

client_key               "#{current_dir}/USER.pem"

下面一行代码告诉 knife 我们正在使用托管服务器。

chef_server_url        'https://api.chef.io/organizations/ORG_NAME'

Using the knife.rb file, the validator knife can now connect to your organization's hosted Opscode.
