IAM / Client / list_roles

list_roles#

IAM.Client.list_roles(**kwargs)#

Lists the IAM roles that have the specified path prefix. If there are none, the operation returns an empty list. For more information about roles, see Working with roles.

Note

IAM resource-listing operations return a subset of the available attributes for the resource. This operation does not return the following attributes, even though they are an attribute of the returned object:

PermissionsBoundary
RoleLastUsed
Tags

To view all of the information for a role, see GetRole.

You can paginate the results using the MaxItems and Marker parameters.

Request Syntax

response = client.list_roles(
    PathPrefix='string',
    Marker='string',
    MaxItems=123
)

Parameters:

PathPrefix (string) –
The path prefix for filtering the results. For example, the prefix /application_abc/component_xyz/ gets all roles whose path starts with /application_abc/component_xyz/.

This parameter is optional. If it is not included, it defaults to a slash (/), listing all roles. This parameter allows (through its regex pattern) a string of characters consisting of either a forward slash (/) by itself or a string that must begin and end with forward slashes. In addition, it can contain any ASCII character from the ! ( \u0021) through the DEL character ( \u007F), including most punctuation characters, digits, and upper and lowercased letters.
Marker (string) – Use this parameter only when paginating results and only after you receive a response indicating that the results are truncated. Set it to the value of the Marker element in the response that you received to indicate where the next call should start.
MaxItems (integer) –
Use this only when paginating results to indicate the maximum number of items you want in the response. If additional items exist beyond the maximum you specify, the IsTruncated response element is true.

If you do not include this parameter, the number of items defaults to 100. Note that IAM might return fewer results, even when there are more results available. In that case, the IsTruncated response element returns true, and Marker contains a value to include in the subsequent call that tells the service where to continue from.

Return type:

Response Structure

(dict) –

Contains the response to a successful ListRoles request.
- Roles (list) –
  
  A list of roles.
  - (dict) –
    
    Contains information about an IAM role. This structure is returned as a response element in several API operations that interact with roles.
    - Path (string) –
      
      The path to the role. For more information about paths, see IAM identifiers in the IAM User Guide.
    - RoleName (string) –
      
      The friendly name that identifies the role.
    - RoleId (string) –
      
      The stable and unique string identifying the role. For more information about IDs, see IAM identifiers in the IAM User Guide.
    - Arn (string) –
      
      The Amazon Resource Name (ARN) specifying the role. For more information about ARNs and how to use them in policies, see IAM identifiers in the IAM User Guide guide.
    - CreateDate (datetime) –
      
      The date and time, in ISO 8601 date-time format, when the role was created.
    - AssumeRolePolicyDocument (string) –
      
      The policy that grants an entity permission to assume the role.
    - Description (string) –
      
      A description of the role that you provide.
    - MaxSessionDuration (integer) –
      
      The maximum session duration (in seconds) for the specified role. Anyone who uses the CLI, or API to assume the role can specify the duration using the optional DurationSeconds API parameter or duration-seconds CLI parameter.
    - PermissionsBoundary (dict) –
      
      The ARN of the policy used to set the permissions boundary for the role.
      
      For more information about permissions boundaries, see Permissions boundaries for IAM identities in the IAM User Guide.
      - PermissionsBoundaryType (string) –
        
        The permissions boundary usage type that indicates what type of IAM resource is used as the permissions boundary for an entity. This data type can only have a value of Policy.
      - PermissionsBoundaryArn (string) –
        
        The ARN of the policy used to set the permissions boundary for the user or role.
    - Tags (list) –
      
      A list of tags that are attached to the role. For more information about tagging, see Tagging IAM resources in the IAM User Guide.
      - (dict) –
        
        A structure that represents user-provided metadata that can be associated with an IAM resource. For more information about tagging, see Tagging IAM resources in the IAM User Guide.
        
        Key (string) –
        
        The key name that can be used to look up or retrieve the associated value. For example, Department or Cost Center are common choices.
        
        Value (string) –
        
        The value associated with this tag. For example, tags with a key name of Department could have values such as Human Resources, Accounting, and Support. Tags with a key name of Cost Center might have values that consist of the number associated with the different cost centers in your company. Typically, many resources have tags with the same key name but with different values.
        
        Note
        Amazon Web Services always interprets the tag Value as a single string. If you need to store an array, you can store comma-separated values in the string. However, you must interpret the value in your code.
    - RoleLastUsed (dict) –
      
      Contains information about the last time that an IAM role was used. This includes the date and time and the Region in which the role was last used. Activity is only reported for the trailing 400 days. This period can be shorter if your Region began supporting these features within the last year. The role might have been used more than 400 days ago. For more information, see Regions where data is tracked in the IAM user Guide.
      - LastUsedDate (datetime) –
        
        The date and time, in ISO 8601 date-time format that the role was last used.
        
        This field is null if the role has not been used within the IAM tracking period. For more information about the tracking period, see Regions where data is tracked in the IAM User Guide.
      - Region (string) –
        
        The name of the Amazon Web Services Region in which the role was last used.
- IsTruncated (boolean) –
  
  A flag that indicates whether there are more items to return. If your results were truncated, you can make a subsequent pagination request using the Marker request parameter to retrieve more items. Note that IAM might return fewer than the MaxItems number of results even when there are more results available. We recommend that you check IsTruncated after every call to ensure that you receive all your results.
- Marker (string) –
  
  When IsTruncated is true, this element is present and contains the value to use for the Marker parameter in a subsequent pagination request.
