在Chef中，蓝图是找出并准确记录服务器上存在的内容的工具。蓝图记录了所需的所有内容，例如导演，软件包，配置文件等。蓝图具有以多种格式拆分服务器信息的功能。其中之一是厨师食谱。这有助于使用Chef配置唯一服务器。
我们需要在需要运行蓝图的节点上安装Python和Git。
步骤1-安装蓝图。
vipin@server:~$ pip install blueprint
步骤2-创建一个蓝图。
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\
xa1mara_S.A..pem not UTF-8 - skipping it
# [blueprint] /etc/ssl/certs/NetLock_Arany_=Class_Gold=_F\xc5\
x91tan\xc3\xbas\xc3\xadtv\xc3\xa1ny.pem not UTF-8 - skipping it
# [blueprint] /etc/ssl/certs/EBG_Elektronik_Sertifika_Hizmet_Sa\
xc4\x9flay\xc4\xb1c\xc4\xb1s\xc4\xb1.pem not UTF-8 - skipping it
# [blueprint] /etc/ssl/certs/Certinomis_-_Autorit\xc3\xa9_Racine.
pem not UTF-8 - skipping it
# [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
步骤3-根据蓝图创建食谱。
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
蓝图是一个Python软件包，可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。每个蓝图都有自己的名称。
可以要求该蓝图以各种共振峰形式显示其Git回购的内容。
user@server:~$ ls -l internal-cookbook /
