Examples

var lambdaRole = new Role(this, "Role", new RoleProps {
                AssumedBy = new ServicePrincipal("lambda.amazonaws.com"),
                Description = "Example role..."
            });

            var stream = new Stream(this, "MyEncryptedStream", new StreamProps {
                Encryption = StreamEncryption.KMS
            });

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

Constructors

RoleProps() 

public RoleProps()

Properties

AssumedBy

The IAM principal (i.e. new ServicePrincipal('sns.amazonaws.com')) which can assume this role.

public IPrincipal AssumedBy { get; set; }

Property Value

IPrincipal

Remarks

You can later modify the assume role policy document by accessing it via the assumeRolePolicy property.

Description

A description of the role.

public string? Description { get; set; }

Property Value

string

Remarks

It can be up to 1000 characters long.

Default: - No description.

ExternalId

(deprecated) ID that the role assumer needs to provide when assuming this role.

[Obsolete("see {@link externalIds}")]
public string? ExternalId { get; set; }

Property Value

string

Remarks

If the configured and provided external IDs do not match, the AssumeRole operation will fail.

Default: No external ID required

Stability: Deprecated

ExternalIds

List of IDs that the role assumer needs to provide one of when assuming this role.

public string[]? ExternalIds { get; set; }

Property Value

string[]

Remarks

If the configured and provided external IDs do not match, the AssumeRole operation will fail.

Default: No external ID required

InlinePolicies

A list of named policies to inline into this role.

public IDictionary<string, PolicyDocument>? InlinePolicies { get; set; }

Property Value

IDictionary<string, PolicyDocument>

Remarks

These policies will be created with the role, whereas those added by addToPolicy are added using a separate CloudFormation resource (allowing a way around circular dependencies that could otherwise be introduced).

Default: - No policy is inlined in the Role resource.

ManagedPolicies

A list of managed policies associated with this role.

public IManagedPolicy[]? ManagedPolicies { get; set; }

Property Value

IManagedPolicy[]

Remarks

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

Default: - No managed policies.

MaxSessionDuration

The maximum session duration that you want to set for the specified role.

public Duration? MaxSessionDuration { get; set; }

Property Value

Duration

Remarks

This setting can have a value from 1 hour (3600sec) to 12 (43200sec) hours.

Anyone who assumes the role from the AWS CLI or API can use the DurationSeconds API parameter or the duration-seconds CLI parameter to request a longer session. The MaxSessionDuration setting determines the maximum duration that can be requested using the DurationSeconds parameter.

If users don't specify a value for the DurationSeconds parameter, their security credentials are valid for one hour by default. This applies when you use the AssumeRole* API operations or the assume-role* CLI operations but does not apply when you use those operations to create a console URL.

Default: Duration.hours(1)

Path

The path associated with this role.

public string? Path { get; set; }

Property Value

string

Remarks

For information about IAM paths, see Friendly Names and Paths in IAM User Guide.

Default: /

PermissionsBoundary

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

public IManagedPolicy? PermissionsBoundary { get; set; }

Property Value

IManagedPolicy

Remarks

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.

Default: - No permissions boundary.

Link: https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_boundaries.html

RoleName

A name for the IAM role.

public string? RoleName { get; set; }

Property Value

string

Remarks

For valid values, see the RoleName parameter for the CreateRole action in the IAM API Reference.

IMPORTANT: 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.

Default: - AWS CloudFormation generates a unique physical ID and uses that ID for the role name.
