Adds or updates an inline policy document that is embedded in the specified IAM role.

When you embed an inline policy in a role, the inline policy is used as part of the role's access (permissions) policy. The role's trust policy is created at the same time as the role, using CreateRole. You can update a role's trust policy using UpdateAssumeRolePolicy. For information about roles, see IAM roles in the IAM User Guide.

A role can also have a managed policy attached to it. To attach a managed policy to a role, use AWS::IAM::Role. To create a new managed policy, use AWS::IAM::ManagedPolicy. For information about policies, see Managed policies and inline policies in the IAM User Guide.

For information about the maximum number of inline policies that you can embed with a role, see IAM and AWS STS quotas in the IAM User Guide.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "Type" : "AWS::IAM::RolePolicy",
  "Properties" : {
      "PolicyDocument" : Json,
      "PolicyName" : String,
      "RoleName" : String
    }
}

YAML

Type: AWS::IAM::RolePolicy
Properties:
  PolicyDocument: Json
  PolicyName: String
  RoleName: String

Properties

PolicyDocument

The policy document.

You must provide policies in JSON format in IAM. However, for AWS CloudFormation templates formatted in YAML, you can provide the policy in JSON or YAML format. AWS CloudFormation always converts a YAML policy to JSON format before submitting it to IAM.

The regex pattern used to validate this parameter is a string of characters consisting of the following:

  • Any printable ASCII character ranging from the space character (\u0020) through the end of the ASCII character range

  • The printable characters in the Basic Latin and Latin-1 Supplement character set (through \u00FF)

  • The special characters tab (\u0009), line feed (\u000A), and carriage return (\u000D)

Role embedded inline policy document with Ref function
