Chef Blueprints
在 Chef 中，Blueprints是找出并准确记录服务器上存在的内容的工具。Blueprints记录了所需的所有内容，例如导演、包、配置文件等。Blueprints能够以各种格式拆分服务器信息。其中之一是ChefCookbook。这有助于使用 Chef 配置唯一的服务器。
工作方法
我们需要在需要运行Blueprints的节点上安装 Python 和 Git。
步骤 1-安装Blueprints。
vipin@server:~$ pip install blueprint
第 2 步-创建Blueprints。
user@server:~$ sudo blueprint create internal-cookbook
# [blueprint] using cached blueprintignore(5) rules
# [blueprint] searching for Python packages
# [blueprint] searching for PEAR/PECL packages
# [blueprint] searching for Yum packages
# [blueprint] searching for Ruby gems
# [blueprint] searching for npm packages
# [blueprint] searching for software built from source
# [blueprint] searching for configuration files
# [blueprint] /etc/ssl/certs/AC_Ra\xc3\xadz_Certic\xc3\

# [blueprint] /etc/ssl/certs/NetLock_Arany_=Class_Gold=_F\xc5\

# [blueprint] /etc/ssl/certs/Certinomis_-_Autorit\xc3\xa9_Racine.

# [blueprint] /etc/ssl/certs/T\xc3\x9cB\xc4\xb0TAK_UEKAE_K\xc3\
xb6k_Sertifika_Hizmet_Sa\xc4\x9flay\xc4\xb1c\xc4\xb1s\xc4\xb1_-_S\
xc3\xbcr\xc3\xbcm_3.pem not UTF-8-skipping it
# [blueprint] searching for APT packages
# [blueprint] searching for service dependencies
第 3 步-根据Blueprints创建Cookbook。
user@server:~$ blueprint show-C internal-cookbook my-server/recipes/default.rb
步骤 4-验证生成文件的内容。
user@server:~$ cat internal-cookbook /recipes/default.rb
#
# Automatically generated by blueprint(7). Edit at your own risk.
#
cookbook_file('/tmp/96468fd1cc36927a027045b223c61065de6bc575.tar')
do
backup false
group 'root'
mode '0644'
owner 'root'
source 'tmp/96468fd1cc36927a027045b223c61065de6bc575.tar'
end
execute('/tmp/96468fd1cc36927a027045b223c61065de6bc575.tar') do
command 'tar xf "/tmp/96468fd1cc36927a027045b223c61065de6bc575.tar"'
cwd '/usr/local'
end
directory('/etc/apt/apt.conf.d') do
...TRUNCATED OUTPUT...
service('ssh') do
action [:enable, :start]
subscribes :restart, resources('cookbook_file[/etc/default/
keyboard]', 'cookbook_file[/etc/default/console-setup]',
'cookbook_file[/etc/default/ntfs-3g]', 'package[openssh-server]',
'execute[96468fd1cc36927a027045b223c61065de6bc575.tar]')
end
工作流脚本
Blueprint 是一个 Python 包，它找出服务器的所有相关配置数据并将其存储在 Git 存储库中。每个Blueprints都有自己的名字。
可以要求Blueprints以各种共振峰显示其 Git 存储库的内容。
user@server:~$ ls-l internal-cookbook /
total 8
drwxrwxr-x 3 vagrant vagrant 4096 Jun 28 06:01 files
-rw-rw-r--1 vagrant vagrant 0 Jun 28 06:01 metadata.rb
drwxrwxr-x 2 vagrant vagrant 4096 Jun 28 06:01 recipes
