AWS::IAM::UserPolicy

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

An IAM user can also have a managed policy attached to it. To attach a managed policy to a user, use AWS::IAM::User. 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 in a user, 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::UserPolicy",
  "Properties" : {
      "PolicyDocument" : Json,
      "PolicyName" : String,

  PolicyDocument: Json
  PolicyName: String
  UserName: String

Properties

PolicyDocument

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.
