@Generated(value="jsii-pacmak/1.84.0 (build 5404dcf)", date="2023-06-19T16:29:57.366Z") @Stability(Stable) public class Role extends Resource implements IRole
IAM Role.

Defines an IAM role. The role is created with an assume policy document associated with the specified AWS service principal defined in serviceAssumeRole.

Example: 

 Role lambdaRole = Role.Builder.create(this, "Role")
         .assumedBy(new ServicePrincipal("lambda.amazonaws.com"))
         .description("Example role...")
         .build();
 Stream stream = Stream.Builder.create(this, "MyEncryptedStream")
         .encryption(StreamEncryption.KMS)
         .build();
 // give lambda permissions to read stream
 stream.grantRead(lambdaRole);

    • fromRoleArn

      @Stability(Stable) @NotNull public static IRole fromRoleArn(@NotNull software.constructs.Construct scope, @NotNull String id, @NotNull String roleArn, @Nullable FromRoleArnOptions options)
      Import an external role by ARN.

      If the imported Role ARN is a Token (such as a CfnParameter.valueAsString or a Fn.importValue()) and the referenced role has a path (like arn:...:role/AdminRoles/Alice), the roleName property will not resolve to the correct value. Instead it will resolve to the first path component. We unfortunately cannot express the correct calculation of the full path name as a CloudFormation expression. In this scenario the Role ARN should be supplied without the path in order to resolve the correct role resource.

      Parameters:
      scope - construct scope. This parameter is required.
      id - construct id. This parameter is required.
      roleArn - the ARN of the role to import. This parameter is required.
      options - allow customizing the behavior of the returned role.

    • fromRoleArn

      @Stability(Stable) @NotNull public static IRole fromRoleArn(@NotNull software.constructs.Construct scope, @NotNull String id, @NotNull String roleArn)
      Import an external role by ARN.

      If the imported Role ARN is a Token (such as a CfnParameter.valueAsString or a Fn.importValue()) and the referenced role has a path (like arn:...:role/AdminRoles/Alice), the roleName property will not resolve to the correct value. Instead it will resolve to the first path component. We unfortunately cannot express the correct calculation of the full path name as a CloudFormation expression. In this scenario the Role ARN should be supplied without the path in order to resolve the correct role resource.

      Parameters:
      scope - construct scope. This parameter is required.
      id - construct id. This parameter is required.
      roleArn - the ARN of the role to import. This parameter is required.

    • fromRoleName

      @Stability(Stable) @NotNull public static IRole fromRoleName(@NotNull software.constructs.Construct scope, @NotNull String id, @NotNull String roleName)

      The imported role is assumed to exist in the same account as the account the scope's containing Stack is being deployed to.

      Parameters:
      scope - This parameter is required.
      id - This parameter is required.
      roleName - This parameter is required.
