User L2 construct ​

Define a new IAM user.

Example ​

ts
const user = new iam.User(this, 'MyUser');

declare const definition: sfn.IChainable;
const stateMachine = new sfn.StateMachine(this, 'StateMachine', {
  definitionBody: sfn.DefinitionBody.fromChainable(definition),
});

//give user permission to send task success to the state machine
stateMachine.grant(user, 'states:SendTaskSuccess');
python
# definition: sfn.IChainable
user = iam.User(self, "MyUser")
state_machine = sfn.StateMachine(self, "StateMachine",
    definition_body=sfn.DefinitionBody.from_chainable(definition)
)

# give user permission to send task success to the state machine
state_machine.grant(user, "states:SendTaskSuccess")
java
IChainable definition;
User user = new User(this, "MyUser");
StateMachine stateMachine = StateMachine.Builder.create(this, "StateMachine")
        .definitionBody(DefinitionBody.fromChainable(definition))
        .build();

//give user permission to send task success to the state machine
stateMachine.grant(user, "states:SendTaskSuccess");
csharp
// Install: dotnet add package Amazon.CDK.Lib
IChainable definition;
var user = new User(this, "MyUser");
var stateMachine = new StateMachine(this, "StateMachine", new StateMachineProps {
    DefinitionBody = DefinitionBody.FromChainable(definition)
});

//give user permission to send task success to the state machine
stateMachine.Grant(user, "states:SendTaskSuccess");
go
// Install: go get github.com/aws/aws-cdk-go/awscdk/v2
var definition IChainable
user := iam.NewUser(this, jsii.String("MyUser"))
stateMachine := sfn.NewStateMachine(this, jsii.String("StateMachine"), &StateMachineProps{
	DefinitionBody: sfn.DefinitionBody_FromChainable(definition),
})

//give user permission to send task success to the state machine
stateMachine.grant(user, jsii.String("states:SendTaskSuccess"))

Initializer ​

python
User(scope: Construct, id: str, props: typing.Optional[UserProps] = None)
java
new User(Construct scope, String id, UserProps props)
csharp
new User(Construct scope, string id, UserProps? props = null)
go
NewUser(Scope Construct, Id *string, Props UserProps)

Construct Props ​

groupsoptionalIGroup[]groupsoptionaltyping.List[IGroup]groupsoptionalList<IGroup>GroupsoptionalIGroup[]Groupsoptional*[]IGroup#
Groups to add this user to.

Default: No groups.

You can also use addToGroup to add this user to a group.

managedPoliciesoptionalIManagedPolicy[]managed_policiesoptionaltyping.List[IManagedPolicy]managedPoliciesoptionalList<IManagedPolicy>ManagedPoliciesoptionalIManagedPolicy[]ManagedPoliciesoptional*[]IManagedPolicy#
A list of managed policies associated with this role.

Default: No managed policies.

You can add managed policies later using addManagedPolicy(ManagedPolicy.fromAwsManagedPolicyName(policyName)).

passwordoptionalSecretValuepasswordoptionalSecretValuepasswordoptionalSecretValuePasswordoptionalSecretValuePasswordoptionalSecretValue#
The password for the user. This is required so the user can access the AWS Management Console.

Default: User won't be able to access the management console without a password.

You can use SecretValue.unsafePlainText to specify a password in plain text or use secretsmanager.Secret.fromSecretAttributes to reference a secret in Secrets Manager.

passwordResetRequiredoptionalbooleanpassword_reset_requiredoptionalboolpasswordResetRequiredoptionalBooleanPasswordResetRequiredoptionalboolPasswordResetRequiredoptional*bool= false#
Specifies whether the user is required to set a new password the next time the user logs in to the AWS Management Console.

If this is set to 'true', you must also specify "initialPassword".

pathoptionalstringpathoptionalstrpathoptionalStringPathoptionalstringPathoptional*string= /#
The path for the user name.

For more information about paths, see IAM Identifiers in the IAM User Guide.

permissionsBoundaryoptionalIManagedPolicypermissions_boundaryoptionalIManagedPolicypermissionsBoundaryoptionalIManagedPolicyPermissionsBoundaryoptionalIManagedPolicyPermissionsBoundaryoptionalIManagedPolicy#
AWS supports permissions boundaries for IAM entities (users or roles).

Default: No permissions boundary.

notes

A permissions boundary is an advanced feature for using a managed policy to set the maximum permissions that an identity-based policy can grant to an IAM entity. An entity's permissions boundary allows it to perform only the actions that are allowed by both its identity-based policies and its permissions boundaries.

userNameoptionalstringuser_nameoptionalstruserNameoptionalStringUserNameoptionalstringUserNameoptional*string#
A name for the IAM user.

Default: Generated by CloudFormation (recommended)

notes

For valid values, see the UserName parameter for the CreateUser action in the IAM API Reference. If you don't specify a name, AWS CloudFormation generates a unique physical ID and uses that ID for the user name.

If you specify a name, you cannot perform updates that require replacement of this resource. You can perform updates that require no or some interruption. If you must replace the resource, specify a new name.

If you specify a name, you must specify the CAPABILITY_NAMED_IAM value to acknowledge your template's capabilities. For more information, see Acknowledging IAM Resources in AWS CloudFormation Templates.

Properties ​

When this Principal is used in an AssumeRole policy, the action to use.
The environment this resource belongs to.
notes

For resources that are created and managed in a Stack (those created by creating new class instances like new Role(), new Bucket(), etc.), this is always the same as the environment of the stack they belong to.

For referenced resources (those obtained from referencing methods like Role.fromRoleArn(), Bucket.fromBucketName(), etc.), they might be different than the stack they were imported into.

Returns: true

applyCrossStackReferenceStrength(strength: ReferenceStrength): voiddef apply_cross_stack_reference_strength(self, strength: ReferenceStrength) -> Nonepublic void applyCrossStackReferenceStrength(ReferenceStrength strength)public void ApplyCrossStackReferenceStrength(ReferenceStrength strength)func ApplyCrossStackReferenceStrength(Strength ReferenceStrength)#
Override the cross-stack reference strength for this resource.
notes · 1 parameter

When set, any cross-stack reference to this resource will use the specified mechanism instead of the global default determined by the @aws-cdk/core:defaultCrossStackReferences context key. This is useful for selectively weakening specific references to avoid the "deadly embrace" problem without changing the app-wide default.

Parameters

  • strengthstrengthstrengthstrengthStrength — - The reference strength to use for this resource.
applyRemovalPolicy(policy: RemovalPolicy): voiddef apply_removal_policy(self, policy: RemovalPolicy) -> Nonepublic void applyRemovalPolicy(RemovalPolicy policy)public void ApplyRemovalPolicy(RemovalPolicy policy)func ApplyRemovalPolicy(Policy RemovalPolicy)#

notes

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Checks if `x` is a construct.
notes · 1 parameter · returns

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters

  • xxxxX — Any object.

Returns: true if x is an object created from a class which extends Construct.

isOwnedResource(construct: IConstruct): boolean@staticmethod def is_owned_resource(construct: IConstruct) -> boolpublic static Boolean isOwnedResource(IConstruct construct)public static bool IsOwnedResource(IConstruct construct)func IsOwnedResource(Construct IConstruct) *boolstatic#

with(...mixins: IMixin[]): IConstructdef with(self, mixins: IMixin) -> IConstructpublic IConstruct with(IMixin mixins)public IConstruct With(IMixin mixins)func With(Mixins IMixin) IConstruct#
Applies one or more mixins to this construct.

Mixins are applied in order. The list of constructs is captured at the start of the call, so constructs added by a mixin will not be visited. Use multiple with() calls if subsequent mixins should apply to added constructs.
