knife download

Use the knife download subcommand to download roles, cookbooks, environments, nodes, and data bags from the Chef Infra Server to the current working directory. It can be used to back up data on the Chef Infra Server, inspect the state of one or more files, or to extract out-of-process changes users may have made to files on the Chef Infra Server, such as if a user made a change that bypassed version source control. This subcommand is often used in conjunction with knife diff, which can be used to see exactly what changes will be downloaded, and then knife upload, which does the opposite of knife download.

Syntax

This subcommand has the following syntax:

knife download [PATTERN...] (options)

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.
--cookbook-version VERSION: The version of a cookbook to download.
-n, --dry-run: Take no action and only print out results. Default: false.
--[no-]diff: Download only new and modified files. Set to false to download all files. Default: --diff.
--[no-]force: Use --force to download files even when the file on the hard drive is identical to the object on the server (role, cookbook, etc.). By default, files are compared to see if they have equivalent content, and local files are only overwritten if they are different. Default: --no-force.
--[no-]purge: Use --purge to delete local files and directories that do not exist on the Chef Infra Server. By default, if a role, cookbook, etc. does not exist on the Chef Infra Server, the local file for said role is left alone and NOT deleted. Default: --no-purge.
--[no-]recurse: Use --no-recurse to disable downloading a directory recursively. Default: --recurse.
--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.

Note
