Chef infra 厨师：在不同的食谱中使用属性

我试图使用一本烹饪书中定义的属性，比如foo，另一本烹饪书中定义的属性，比如bar。我得到错误“nil:NilClass的未定义方法”[]”

以上是我厨师的结构

solo.rb

cookbook_path File.expand_path("../chef/cookbooks", __FILE__)
json_attribs File.expand_path("../chef/roles/roles.json", __FILE__)
log_location STDOUT
log_level :debug

default['foo']['var1'] = "Hello"

default['bar']['var1'] = node['foo']['var1']

name 'foo'
depends 'bar'

name 'bar'
depends 'foo'

default['foo']['var1'] = "Hello"

default['bar']['var1'] = node['foo']['var1']

log "The value of ['bar']['var1'] is #{node['bar']['var1']}. The value of ['foo']['var1'] is also #{node['foo']['var1']}"

name 'bar'
depends 'foo'

roles.json

{
    "run_list": ["recipe[foo::default]"]
}

foo/attributes/default.rb

cookbook_path File.expand_path("../chef/cookbooks", __FILE__)
json_attribs File.expand_path("../chef/roles/roles.json", __FILE__)
log_location STDOUT
log_level :debug

default['foo']['var1'] = "Hello"

default['bar']['var1'] = node['foo']['var1']

name 'foo'
depends 'bar'

name 'bar'
depends 'foo'

default['foo']['var1'] = "Hello"

default['bar']['var1'] = node['foo']['var1']

log "The value of ['bar']['var1'] is #{node['bar']['var1']}. The value of ['foo']['var1'] is also #{node['foo']['var1']}"

name 'bar'
depends 'foo'

bar/attributes/default.rb

cookbook_path File.expand_path("../chef/cookbooks", __FILE__)
json_attribs File.expand_path("../chef/roles/roles.json", __FILE__)
log_location STDOUT
log_level :debug

default['foo']['var1'] = "Hello"

default['bar']['var1'] = node['foo']['var1']

name 'foo'
depends 'bar'

name 'bar'
depends 'foo'

default['foo']['var1'] = "Hello"

default['bar']['var1'] = node['foo']['var1']

log "The value of ['bar']['var1'] is #{node['bar']['var1']}. The value of ['foo']['var1'] is also #{node['foo']['var1']}"

name 'bar'
depends 'foo'

foo/metadata.rb

cookbook_path File.expand_path("../chef/cookbooks", __FILE__)
json_attribs File.expand_path("../chef/roles/roles.json", __FILE__)
log_location STDOUT
log_level :debug

default['foo']['var1'] = "Hello"

default['bar']['var1'] = node['foo']['var1']

name 'foo'
depends 'bar'

name 'bar'
depends 'foo'

default['foo']['var1'] = "Hello"

default['bar']['var1'] = node['foo']['var1']

log "The value of ['bar']['var1'] is #{node['bar']['var1']}. The value of ['foo']['var1'] is also #{node['foo']['var1']}"

name 'bar'
depends 'foo'

当我运行查询

chef solo-c solo.rb时，我得到如下错误

================================================================================
Recipe Compile Error in ../chef/cookbooks/bar/attributes/default.rb
================================================================================

NoMethodError
-------------
undefined method `[]' for nil:NilClass

Relevant File Content:
----------------------
Recipe Compile Error in ../chef/cookbooks/bar/attributes/default.rb:
1>> default['bar']['var1'] = node['foo']['var1']

这里
foo
是我的应用程序，
bar
是。如何导入属性？？？
您已反转了cookbook依赖项。如果您想在bar cookbook中使用
节点['foo']['var1']
属性，那么bar cookbook应该依赖于foo cookbook，而不是相反

在foo/metadata.rb中去掉依赖于
的“bar”
，并创建bar/metadata.rb

cookbook_path File.expand_path("../chef/cookbooks", __FILE__)
json_attribs File.expand_path("../chef/roles/roles.json", __FILE__)
log_location STDOUT
log_level :debug

default['foo']['var1'] = "Hello"

default['bar']['var1'] = node['foo']['var1']

name 'foo'
depends 'bar'

name 'bar'
depends 'foo'

default['foo']['var1'] = "Hello"

default['bar']['var1'] = node['foo']['var1']

log "The value of ['bar']['var1'] is #{node['bar']['var1']}. The value of ['foo']['var1'] is also #{node['foo']['var1']}"

name 'bar'
depends 'foo'

“Foo”是我的申请，“bar”是chef maven。我在“foo”中依赖maven（bar）。现在我尝试在关于foo的酒吧里添加依赖项，但错误仍然是一样的。你能给我们举个例子看看吗？或者是真正的烹饪书，或者只是foo和bar？增加了一个例子。老实说，我很难理解你想做什么。如果您使用的是Chef Maven cookbook，为什么要修改“Maven/attributes/default.rb”并将属性值设置为您自己的应用程序cookbook中的属性？
