@Generated(value="jsii-pacmak/1.97.0 (build 729de35)", date="2024-04-24T21:00:30.878Z") @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: 

 IChainable definition;
 Role role = Role.Builder.create(this, "Role")
         .assumedBy(new ServicePrincipal("lambda.amazonaws.com"))
         .build();
 StateMachine stateMachine = StateMachine.Builder.create(this, "StateMachine")
         .definitionBody(DefinitionBody.fromChainable(definition))
         .build();
 // Give role permission to get execution history of ALL executions for the state machine
 stateMachine.grantExecution(role, "states:GetExecutionHistory");

    • customizeRoles

      @Stability(Stable) public static void customizeRoles(@NotNull software.constructs.Construct scope, @Nullable CustomizeRolesOptions options)
      Customize the creation of IAM roles within the given scope.

      It is recommended that you do not use this method and instead allow CDK to manage role creation. This should only be used in environments where CDK applications are not allowed to created IAM roles.

      This can be used to prevent the CDK application from creating roles within the given scope and instead replace the references to the roles with precreated role names. A report will be synthesized in the cloud assembly (i.e. cdk.out) that will contain the list of IAM roles that would have been created along with the IAM policy statements that the role should contain. This report can then be used to create the IAM roles outside of CDK and then the created role names can be provided in usePrecreatedRoles.

      Example: 

       App app;
 Role.customizeRoles(app, CustomizeRolesOptions.builder()
         .usePrecreatedRoles(Map.of(
                 "ConstructPath/To/Role", "my-precreated-role-name"))
         .build());

      Parameters:
      scope - construct scope to customize role creation. This parameter is required.
      options - options for configuring role creation.

    • customizeRoles

      @Stability(Stable) public static void customizeRoles(@NotNull software.constructs.Construct scope)
      Customize the creation of IAM roles within the given scope.

      It is recommended that you do not use this method and instead allow CDK to manage role creation. This should only be used in environments where CDK applications are not allowed to created IAM roles.

      This can be used to prevent the CDK application from creating roles within the given scope and instead replace the references to the roles with precreated role names. A report will be synthesized in the cloud assembly (i.e. cdk.out) that will contain the list of IAM roles that would have been created along with the IAM policy statements that the role should contain. This report can then be used to create the IAM roles outside of CDK and then the created role names can be provided in usePrecreatedRoles.

      Example: 

       App app;
 Role.customizeRoles(app, CustomizeRolesOptions.builder()
         .usePrecreatedRoles(Map.of(
                 "ConstructPath/To/Role", "my-precreated-role-name"))
         .build());

      Parameters:
      scope - construct scope to customize role creation. This parameter is required.

    • 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.
