knife deps¶

Use the knife deps subcommand to identify dependencies for a node, role, or cookbook.

Syntax¶

This subcommand has the following syntax:

$ knife deps (options)

Note

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.
--concurrency: The number of allowed concurrent connections. Default: 10.
--[no-]recurse: Use --recurse to list dependencies recursively. This option can only be used when --tree is set to true. Default: --no-recurse.
--remote: 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.
--tree: Show dependencies in a visual tree structure (including duplicates, if they exist). Default: false.

Note

See config.rb for more information about how to add certain knife options as settings in the config.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
