使用Berkshelf解决递归git cookbook依赖关系

tl；dr版本：Berkshell是否能够解决基于Git的食谱中的递归依赖关系？如果是，如何解决？

我试着用Berkshelf管理我的厨师烹饪书依赖性。这些食谱都存储在内部Git存储库中。依赖项如下所示：

env_dockerhub_dev 
  >>depends on>> app_dockerhub 
    >>depends on>> app_docker

我的项目中的主Berksfile如下所示：

source "https://supermarket.chef.io"

cookbook "env_dockerhub_dev", git: "git@URL_TO_GIT_SERVER/chef_env_dockerhub_dev.git"

name             'env_dockerhub_dev'
...
depends          'app_dockerhub'
depends          'base_ubuntu'

source "https://supermarket.chef.io"

cookbook "app_dockerhub", git: "git@URL_TO_GIT_SERVER/chef_app_dockerhub.git"
cookbook "base_ubuntu", git: "git@URL_TO_GIT_SERVER/chef_base_ubuntu.git"

source "https://supermarket.chef.io"

# the main cookbook
cookbook "env_dockerhub_dev", git: "git@URL_TO_GIT_SERVER/chef_env_dockerhub_dev.git"

# the cookbooks that are "recursively" 
cookbook "app_dockerhub", git: "git@gURL_TO_GIT_SERVER/chef_app_dockerhub.git"
cookbook "app_docker", git: "git@URL_TO_GIT_SERVER/chef_app_docker.git"

env_dockerhub_dev

cookbook有一个

metadata.rb

如下所示：

source "https://supermarket.chef.io"

cookbook "env_dockerhub_dev", git: "git@URL_TO_GIT_SERVER/chef_env_dockerhub_dev.git"

name             'env_dockerhub_dev'
...
depends          'app_dockerhub'
depends          'base_ubuntu'

source "https://supermarket.chef.io"

cookbook "app_dockerhub", git: "git@URL_TO_GIT_SERVER/chef_app_dockerhub.git"
cookbook "base_ubuntu", git: "git@URL_TO_GIT_SERVER/chef_base_ubuntu.git"

source "https://supermarket.chef.io"

# the main cookbook
cookbook "env_dockerhub_dev", git: "git@URL_TO_GIT_SERVER/chef_env_dockerhub_dev.git"

# the cookbooks that are "recursively" 
cookbook "app_dockerhub", git: "git@gURL_TO_GIT_SERVER/chef_app_dockerhub.git"
cookbook "app_docker", git: "git@URL_TO_GIT_SERVER/chef_app_docker.git"

还有一个像这样的

Berksfile

：

source "https://supermarket.chef.io"

cookbook "env_dockerhub_dev", git: "git@URL_TO_GIT_SERVER/chef_env_dockerhub_dev.git"

name             'env_dockerhub_dev'
...
depends          'app_dockerhub'
depends          'base_ubuntu'

source "https://supermarket.chef.io"

cookbook "app_dockerhub", git: "git@URL_TO_GIT_SERVER/chef_app_dockerhub.git"
cookbook "base_ubuntu", git: "git@URL_TO_GIT_SERVER/chef_base_ubuntu.git"

source "https://supermarket.chef.io"

# the main cookbook
cookbook "env_dockerhub_dev", git: "git@URL_TO_GIT_SERVER/chef_env_dockerhub_dev.git"

# the cookbooks that are "recursively" 
cookbook "app_dockerhub", git: "git@gURL_TO_GIT_SERVER/chef_app_dockerhub.git"
cookbook "app_docker", git: "git@URL_TO_GIT_SERVER/chef_app_docker.git"

现在运行

berks install

时，我收到以下错误消息：

Resolving cookbook dependencies...

Fetching 'env_dockerhub_dev' from git@URL_TO_GIT_SERVER/chef_env_dockerhub_dev.git (at master)

Unable to find a solution for demands: env_dockerhub_dev (0.1.0)

当我将所有内部烹饪书的所有Git URL添加到“main”Berksfile（项目根目录中的Berksfile）中时，我可以解决这个问题，如下所示：

source "https://supermarket.chef.io"

cookbook "env_dockerhub_dev", git: "git@URL_TO_GIT_SERVER/chef_env_dockerhub_dev.git"

name             'env_dockerhub_dev'
...
depends          'app_dockerhub'
depends          'base_ubuntu'

source "https://supermarket.chef.io"

cookbook "app_dockerhub", git: "git@URL_TO_GIT_SERVER/chef_app_dockerhub.git"
cookbook "base_ubuntu", git: "git@URL_TO_GIT_SERVER/chef_base_ubuntu.git"

source "https://supermarket.chef.io"

# the main cookbook
cookbook "env_dockerhub_dev", git: "git@URL_TO_GIT_SERVER/chef_env_dockerhub_dev.git"

# the cookbooks that are "recursively" 
cookbook "app_dockerhub", git: "git@gURL_TO_GIT_SERVER/chef_app_dockerhub.git"
cookbook "app_docker", git: "git@URL_TO_GIT_SERVER/chef_app_docker.git"

无论如何，我认为这不应该是解决这个问题的办法

谢谢你的帮助

好吧——读了这篇文章，我想我发现这真的是不可能的。仍然不明白为什么——但这是另一个问题：-）

正如我在问题中提到的，解决方案是在顶级Berksfile中添加所有cookbook依赖项及其git URL：

source "https://supermarket.chef.io"

# the main cookbook
cookbook "env_dockerhub_dev", git: "git@URL_TO_GIT_SERVER/chef_env_dockerhub_dev.git"

# other cookbook dependencies (resolved recursively)
cookbook "app_dockerhub", git: "git@gURL_TO_GIT_SERVER/chef_app_dockerhub.git"
cookbook "app_docker", git: "git@URL_TO_GIT_SERVER/chef_app_docker.git"

我的对策是使用一种新的方法。我没有从Git repos加载存储库，而是将berksapi服务器指向我们的Chef服务器
