[16] DevOps 自动化运维工具Chef----如何在本地运行cookbooks里面的配方？

在这节中，我们将会分享如何在Chef的客户端通过chef-zero里运行cookbooks里面的配方。下面看具体的步骤，

@创建下面的文件结构

.chef
cookbooks
test.json

@ .chef目录下指定访问Chef-zero服务器的地址和私钥

.chef目录的下面的后缀名为.pem的私钥可以为任何格式正确的私钥文件
具体目录如下：



其中，knife.rb的内容如下：
current_dir = File.dirname(__FILE__)
log_level :info
log_location STDOUT
#chef_server_url 'http://127.0.0.1:8889'
node_name 'dsc-5'
#cookbook_path ["#{current_dir}/../cookbooks"]
client_key "#{current_dir}/test.pem"

@ cookbooks目录下面的内容

其中metadata.rb如下：
name 'starter'
description 'A basic starter cookbook'
version '1.0.0'
maintainer 'Awesome Company, Inc.'
maintainer_email 'you@example.com'

其只要是cookbooks的说明
recipes里面包含一个default.rb
其内容如下：
# This is a Chef recipe file. It can be used to specify resources which will
# apply configuration to a server.

log "Welcome to Chef1111, #{node["starter_name"]}!" do
level :info
end

dsc_script 'BackupUser' do
code <<-EOH
$user = 'backup33'
$password = ConvertTo-SecureString -String "YourPass$(random)" -AsPlainText -Force
$cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $user, $password

User $user
{
UserName = $user
Password = $cred
Description = 'Backup operator'
Ensure = "Present"
Disabled = $false
PasswordNeverExpires = $true
PasswordChangeRequired = $false
}
EOH

configuration_data <<-EOH
@{
AllNodes = @(
@{
NodeName = "localhost";
PSDscAllowPlainTextPassword = $true
})
}
EOH
end
# For more information, see the documentation: https://docs.chef.io/essentials_cookbook_recipes.html

@test.json的内容

在test.json里面可以制定chef client运行的任务清单，比如
{
"run_list": [ "recipe[starter]" ]
}

上面会调用C:\chef\chef-repo\cookbooks\starter\recipes下默认的default.rb； 如果还有其他的rb文件，可以在starter后面加上：：然后写上rb的文件名。
比如，{
"run_list": [ "recipe[starter:another]" ]
}

@运行命令

切换到c:\chef\chef-repo 目录，然后运行C:\chef\chef-repo>chef-client --local-mode -j .\test.json

@运行结果

运行结果如下：
C:\chef\chef-repo>chef-client --local-mode -j .\test.json
