Note

This topic is about using the Chef management console to manage roles.

A role is a way to define certain patterns and processes that exist across nodes in an organization as belonging to a single job function. Each role consists of zero (or more) attributes and a run-list. Each node can have zero (or more) roles assigned to it. When a role is run against a node, the configuration details of that node are compared against the attributes of the role, and then the contents of that role’s run-list are applied to the node’s configuration details. When a Chef Infra Client runs, it merges its own attributes and run-lists with those contained within each assigned role.

Manage

Roles can be managed from the Chef management console web user interface.

Run-lists

A run-list defines all of the information necessary for Chef to configure a node into the desired state. A run-list is:

  • An ordered list of roles and/or recipes that are run in the exact order defined in the run-list; if a recipe appears more than once in the run-list, Chef Infra Client will not run it twice
  • Always specific to the node on which it runs; nodes may have a run-list that is identical to the run-list used by other nodes
  • Stored as part of the node object on the Chef server
  • Maintained using knife and then uploaded from the workstation to the Chef Infra Server, or maintained using Chef Automate

Edit Role Run-list

To edit the run-list for a role:

  1. Open the Chef management console.

Override Attributes

An override attribute is automatically reset at the start of every Chef Infra Client run and has a higher attribute precedence than default, force_default, and normal attributes. An override attribute is most often specified in a recipe, but can be specified in an attribute file, for a role, and/or for an environment. A cookbook should be authored so that it uses override attributes only when required.

Permissions

Permissions are used in the Chef Infra Server to define how users and groups can interact with objects on the server. Permissions are configured for each organization.

The Chef Infra Server includes the following object permissions:

PermissionDescription
DeleteUse the Delete permission to define which users and groups may delete an object. This permission is required for any user who uses the knife [object] delete [object_name] argument to interact with objects on the Chef Infra Server.
GrantUse the Grant permission to define which users and groups may configure permissions on an object. This permission is required for any user who configures permissions using the Administration tab in the Chef management console.
ReadUse the Read permission to define which users and groups may view the details of an object. This permission is required for any user who uses the knife [object] show [object_name] argument to interact with objects on the Chef Infra Server.
UpdateUse the Update permission to define which users and groups may edit the details of an object. This permission is required for any user who uses the knife [object] edit [object_name] argument to interact with objects on the Chef Infra Server and for any Chef Infra Client to save node data to the Chef Infra Server at the conclusion of a Chef Infra Client run.
