Berkshelf 的 Vagrant Chef 供应忽略环境版本
Vagrant chef provision with Berkshelf ignores environment versions
我们当前的设置是，我们希望重新使用服务器管理员提供的 Chef 食谱来配置我们的开发环境。问题是，我们不能更改原始食谱，也不想使用确切的食谱（由于某些部分不需要）。
与实时基础架构相比，我们将使用 Vagrant 管理的 VM - 尽可能接近实时基础架构。
所以计划是在我们这边创建一个简单的食谱，需要我们的服务器提供商提供原始服务器食谱，并调用所需的食谱。
一切都已经工作得很好，食谱是从 github（私人仓库）下载的，作为 Berkshelf 的依赖项，我们的自定义食谱只是调用我们想要的食谱 运行。
各自的Vagrantfile就这么简单：
Vagrant.configure(2) do |config|
config.vm.box = "bento/centos-6.7"
config.omnibus.chef_version = :latest
config.berkshelf.enabled = true
config.vm.provision :chef_zero do |chef|
chef.cookbooks_path = ['site-cookbooks']
chef.data_bags_path = "data_bags"
chef.nodes_path = "nodes"
chef.roles_path = "roles"
chef.environments_path = "environments"
chef.add_role "cms"
chef.environment = "development"
end
end
而我们的Berksfile只有：
source 'https://supermarket.chef.io'
cookbook '1000-server', git: 'git@github.com:somewhere/1000-server.git'
cookbook 'main', path: './site-cookbooks/main'
整体项目结构如下：
Root

现在的诀窍是，1000-server 说明书的 metadata.rb 中的所有依赖项都不受版本限制。这是留给环境的。
metadata.rb 截图：
depends 'apt'
depends 'automatic_updates'
development.json（来自 main 食谱）snip
"cookbook_versions": {
"apt": "= 2.9.2",
"automatic_updates": "= 0.2.0",
....
}
其他环境当然可能使用不同的版本。这种方法在使用常规 Chef 部署的实时环境中工作得很好。
对于使用 Vagrant 的开发部分，我们 运行 遇到了问题。在 Vagrant 的供应阶段，环境特定版本似乎被忽略了。只有当机器本身上 chef-zero 然后 运行s 时，环境才会请求提供的不同版本。
这对于 apt 食谱来说很明显。在 vagrant 供应期间，供应版本 4.0.0（这是最新的）。然而，当开发角色融合时，存在版本冲突，因为此环境需要版本 2.9.2.

我当然可以将这些依赖项固定在我们的 metadata.rb 主文件中，但我猜这样会破坏这里的目的，并且不允许我们切换到不同的环境（例如生产环境），也不总是使用与 1000-server 食谱相同的版本（或 1000-server 食谱的不同版本）
我看到这个人对 kitchen 有同样的问题，但我想这对 Vagrant 不起作用。关于如何解决环境问题的任何想法？
关于如何解决这个问题的任何想法？或者这是我们
Chef Zero 中的版本约束求解器故意非常简单，不像真正的 Chef Server 那样功能齐全。环境级约束通常用于生产-y 覆盖等，而给定食谱实际需要的功能属于相关的 metadata.rb 文件。您可能还想查看 berks apply 命令以 运行 另一个方向的同步。
我们当前的设置是，我们希望重新使用服务器管理员提供的 Chef 食谱来配置我们的开发环境。问题是，我们不能更改原始食谱，也不想使用确切的食谱（由于某些部分不需要）。
与实时基础架构相比，我们将使用 Vagrant 管理的 VM - 尽可能接近实时基础架构。 所以计划是在我们这边创建一个简单的食谱，需要我们的服务器提供商提供原始服务器食谱，并调用所需的食谱。
一切都已经工作得很好，食谱是从 github（私人仓库）下载的，作为 Berkshelf 的依赖项，我们的自定义食谱只是调用我们想要的食谱 运行。
各自的Vagrantfile就这么简单：
Vagrant.configure(2) do |config|
config.vm.box = "bento/centos-6.7"
config.omnibus.chef_version = :latest
config.berkshelf.enabled = true
config.vm.provision :chef_zero do |chef|
chef.cookbooks_path = ['site-cookbooks']
chef.data_bags_path = "data_bags"
chef.nodes_path = "nodes"
chef.roles_path = "roles"
chef.environments_path = "environments"
chef.add_role "cms"
chef.environment = "development"
end
end
而我们的Berksfile只有：
source 'https://supermarket.chef.io'
cookbook '1000-server', git: 'git@github.com:somewhere/1000-server.git'
cookbook 'main', path: './site-cookbooks/main'
整体项目结构如下：

现在的诀窍是，1000-server 说明书的 metadata.rb 中的所有依赖项都不受版本限制。这是留给环境的。
metadata.rb 截图：
depends 'apt'
depends 'automatic_updates'
development.json（来自 main 食谱）snip
"cookbook_versions": {
"apt": "= 2.9.2",
"automatic_updates": "= 0.2.0",
....
}
其他环境当然可能使用不同的版本。这种方法在使用常规 Chef 部署的实时环境中工作得很好。
对于使用 Vagrant 的开发部分，我们 运行 遇到了问题。在 Vagrant 的供应阶段，环境特定版本似乎被忽略了。只有当机器本身上 chef-zero 然后 运行s 时，环境才会请求提供的不同版本。
这对于 apt 食谱来说很明显。在 vagrant 供应期间，供应版本 4.0.0（这是最新的）。然而，当开发角色融合时，存在版本冲突，因为此环境需要版本 2.9.2.

我当然可以将这些依赖项固定在我们的 metadata.rb 主文件中，但我猜这样会破坏这里的目的，并且不允许我们切换到不同的环境（例如生产环境），也不总是使用与 1000-server 食谱相同的版本（或 1000-server 食谱的不同版本）
我看到这个人对 kitchen 有同样的问题，但我想这对 Vagrant 不起作用。关于如何解决环境问题的任何想法？
关于如何解决这个问题的任何想法？或者这是我们
Chef Zero 中的版本约束求解器故意非常简单，不像真正的 Chef Server 那样功能齐全。环境级约束通常用于生产-y 覆盖等，而给定食谱实际需要的功能属于相关的 metadata.rb 文件。您可能还想查看 berks apply 命令以 运行 另一个方向的同步。
