AWS::IAM::GroupPolicy

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

A group can also have managed policies attached to it. To attach a managed policy to a group, use AWS::IAM::Group. 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 group, see IAM and Amazon STS quotas in the IAM User Guide.

Syntax

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

JSON


{
  "Type" : "AWS::IAM::GroupPolicy",
  "Properties" : {
      "GroupName" : String,
      "PolicyDocument" : Json,
      "PolicyName" : String
    }
}
