Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as iam from '@aws-cdk/aws-iam';
const canonicalUserPrincipal = new iam.CanonicalUserPrincipal('canonicalUserId');

Initializer

new CanonicalUserPrincipal(canonicalUserId: string)

Parameters

• canonicalUserId string — unique identifier assigned by AWS for every account.

Properties

Name	Type	Description
assumeRoleAction	string	When this Principal is used in an AssumeRole policy, the action to use.
canonicalUserId	string	unique identifier assigned by AWS for every account.
grantPrincipal	IPrincipal	The principal to grant permissions to.
policyFragment	PrincipalPolicyFragment	Return the policy fragment that identifies this principal in a Policy.
principalAccount?	string	The AWS account ID of this principal.

---

assumeRoleAction

Type: string

When this Principal is used in an AssumeRole policy, the action to use.

---

canonicalUserId

Type: string

unique identifier assigned by AWS for every account.

root user and IAM users for an account all see the same ID. (i.e. 79a59df900b949e55d96a1e698fbacedfd6e09d98eacf8f8d5218e7cd47ef2be)

---

grantPrincipal

Type: IPrincipal

The principal to grant permissions to.

---

policyFragment

Type: PrincipalPolicyFragment

Return the policy fragment that identifies this principal in a Policy.

---

principalAccount?

Type: string (optional)

The AWS account ID of this principal.

Can be undefined when the account is not known (for example, for service principals). Can be a Token - in that case, it's assumed to be AWS::AccountId.
