Microsoft Windows only. The permissions for users and groups in a Microsoft Windows environment. Creates a temporary file and then allows execution of commands or Ruby code.
If this code evaluates to true, the file is created. If the code evaluates to false, an error is raised. The types for this property are a block, string, or a symbol. When specified as a block, it returns true or false. When specified as a string, it is executed as a system command. It returns true if the command returns 0 as its exit status code and false if the command returns a non-zero exit status code.
When using a built-in verifier symbol it returns true if the verifier succeeds else it returns false. A block is arbitrary Ruby defined within the resource block by using the verify property.
When a block returns true , Chef Infra Client will continue to update the file as appropriate. An error will be raised if the executed command returns a non-zero exit status code.
If a string, block or symbol returns false , the Chef Infra Client run will stop and an error is raised. Atomic updates are used with file -based resources to help ensure that file updates can be made when updating a binary or if disk space runs out. Atomic updates are enabled by default.
On certain platforms, and after a file has been moved into place, Chef Infra Client may modify file permissions to support features specific to those platforms. On platforms with SELinux enabled, Chef Infra Client will fix up the security contexts after a file has been moved into the correct location by running the restorecon command. The rights property can be used in a recipe to manage access control lists ACLs , which allow permissions to be given to multiple users and groups.
Use the rights property can be used as many times as necessary; Chef Infra Client will apply them to the file or directory as required.
The syntax for the rights property is as follows:. Use to specify which rights are granted to the principal. Integers used for permissions must match the following list FileSystemRights Enum fields. Use to specify a group or user. The principal can be specified by either name or SID. Chef Infra Client does not need to know if a principal is a user or a group.
Manage the Server. Management Console. Click Policy. Click Cookbooks. Select a cookbook. Click the Details tab:. When a cookbook is loaded during a chef-client run, these attributes are compared to the attributes that are already present on the node. Attributes that are defined in attribute files are first loaded according to cookbook order.
For each cookbook, attributes in the default. When the cookbook attributes take precedence over the default attributes, the chef-client will apply those new settings and values during the chef-client run on the node. Definitions A definition is code that is reused across recipes, similar to a compile-time macro. Though a definition behaves like a resource, some key differences exist. Warning Starting with chef-client Select a file. 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.
The path to the chef-repo. This setting will override the default path to the chef-repo. Download only new and modified files. Set to false to download all files. Default: --diff. If a cookbook is frozen and the --force option is not specified, knife will return an error message similar to the following:. A cookbook defines a scenario and contains everything that is required to support that scenario: Recipes that specify which Chef Infra built-in resources to use, as well as the order in which they are to be applied Attribute values, which allow environment-based configurations such as dev or prodution.
Custom Resources for extending Chef Infra beyond the built-in resources. Files and Templates for distributing information to systems. Custom Ohai Plugins for extending system configuration collection beyond the Ohai defaults.
The metadata. Note Review the list of common options available to this and all knife subcommands and plugins. Note See config. Warning This feature is deprecated in favor of Cookstyle and ChefSpec. Note Use a chefignore file to prevent the upload of specific files and file types, such as temporary files or files placed in folders by version control systems.
