An IAM principal that represents an AWS service (i.e. sqs.amazonaws.com).

Example

const lambdaRole = new iam.Role(this, 'Role', {
  assumedBy: new iam.ServicePrincipal('lambda.amazonaws.com'),
  description: 'Example role...',
});

const stream = new kinesis.Stream(this, 'MyEncryptedStream', {
  encryption: kinesis.StreamEncryption.KMS,
});

// give lambda permissions to read stream
stream.grantRead(lambdaRole);

Initializer

new ServicePrincipal(service: string, opts?: ServicePrincipalOpts)

Parameters

• service string — AWS service (i.e. sqs.amazonaws.com).
• opts ServicePrincipalOpts

---

dedupeString()

public dedupeString(): string

• string

Return whether or not this principal is equal to the given principal.

---

toJSON()

public toJSON(): { [string]: string[] }

Returns

• { [string]: string[] }

JSON-ify the principal.

Used when JSON.stringify() is called

---

toString()

public toString(): string

Returns

• string

Returns a string representation of an object.

---

withConditions(conditions)

public withConditions(conditions: { [string]: any }): PrincipalBase

Parameters

• conditions { [string]: any }

Returns

• PrincipalBase

Returns a new PrincipalWithConditions using this principal as the base, with the passed conditions added.

When there is a value for the same operator and key in both the principal and the conditions parameter, the value from the conditions parameter will be used.

---

withSessionTags()

public withSessionTags(): PrincipalBase

Returns

• PrincipalBase

Returns a new principal using this principal as the base, with session tags enabled.

static servicePrincipalName(service)

public static servicePrincipalName(service: string): string

• service string

Returns

• string

Translate the given service principal name based on the region it's used in.

For example, for Chinese regions this may (depending on whether that's necessary for the given service principal) append .cn to the name.

The region-info module is used to obtain this information. Example

const principalName = iam.ServicePrincipal.servicePrincipalName('ec2.amazonaws.com');
