I am trying to run chef-solo, and I have the following configuration

```
/var/chef

├── cookbooks
│   ├── cc_db
│   │   ├── Berksfile
│   │   ├── Berksfile.lock
│   │   ├── chefignore
│   │   ├── metadata.rb
│   │   ├── recipes
│   │   │   └── default.rb
├── node.json
└── solo.rb

```

node.json

```
{
  "run_list": [ "recipe[cc_db]" ]
}

```

solo.rb

```
file_cache_path "/var/chef"
  cookbook_path "/var/chef/cookbooks"
  json_attribs "/var/chef/node.json"

```

metadata.rb

```
depends 'database', '~> 5.1.2'
depends 'mysql2_chef_gem', '~> 1.0'

```

I've gotten this to work in a kitchen-test environment, but I'm trying it now on a different server using chef-solo.

Whenever I run:
chef-solo -c solo.rb

I get:

```
resolving cookbooks for run list: ["cc_db"]

```

I'm confused because the database cookbook seem to be installed with berks, but chef isn't picking it up.

any help would be greatly appreciated.

thanks.
