Use the knife deps subcommand to identify dependencies for a node, role, or cookbook.
This subcommand has the following syntax:
$ knife deps (options)
Review the list of common options available to this (and all) knife subcommands and plugins.
This subcommand has the following options:
- --chef-repo-path PATH
- The path to the chef-repo. This setting will override the default path to the chef-repo. Default: same value as specified by chef_repo_path in client.rb.
- The number of allowed concurrent connections. Default: 10.
- Use --recurse to list dependencies recursively. This option can only be used when --tree is set to true. Default: --no-recurse.
- Determine dependencies from objects located on the Chef server instead of in the local chef-repo. Default: false.
- --repo-mode MODE
- The layout of the local chef-repo. Possible values: static, everything, or hosted_everything. Use static for just roles, environments, cookbooks, and data bags. By default, everything and hosted_everything are dynamically selected depending on the server type. Default: everything / hosted_everything.
- Show dependencies in a visual tree structure (including duplicates, if they exist). Default: false.
See knife.rb for more information about how to add certain knife options as settings in the knife.rb file.
The following examples show how to use this knife subcommand:
Find dependencies for a node
$ knife deps nodes/node_name.json
Find dependencies for a role
$ knife deps roles/role_name.json
Find dependencies for a cookbook
$ knife deps cookbooks/cookbook_name.json
Find dependencies for an environment
$ knife deps environments/environment_name.json
Find dependencies for a combination of nodes, roles, and so on
To find the dependencies for a combination of nodes, cookbooks, roles, and/or environments:
$ knife deps cookbooks/git.json cookbooks/github.json roles/base.json environments/desert.json nodes/mynode.json
Use a wildcard
A wildcard can be used to return all of the child nodes. For example, all of the environments:
$ knife deps environments/*.json
Return as tree
Use the --tree option to view the results with structure:
$ knife deps roles/webserver.json
to return something like:
roles/webserver.json roles/base.json cookbooks/github cookbooks/git cookbooks/users cookbooks/apache2
Pass knife deps output to knife upload
The output of knife deps can be passed to knife upload:
$ knife upload `knife deps nodes/*.json
Pass knife deps output to knife xargs
The output of knife deps can be passed to knife xargs:
$ knife deps nodes/*.json | xargs knife upload
