```
    The full Amazon Resource Name (ARN) of the task definition.
    
    Returns:
    
    The full Amazon Resource Name (ARN) of the task definition.
  - containerDefinitions
```
public List<ContainerDefinition> containerDefinitions()
```
    A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

```
    The name of a family that this task definition is registered to. A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.
    
    Returns:
    
    The name of a family that this task definition is registered to. A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.
  - taskRoleArn
```
public String taskRoleArn()
```
    The short name or full Amazon Resource Name (ARN) of the AWS Identity and Access Management (IAM) role that grants containers in the task permission to call AWS APIs on your behalf. For more information, see Amazon ECS Task Role in the Amazon Elastic Container Service Developer Guide.
    
    IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code in order to take advantage of the feature. For more information, see Windows IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide.
    
    Returns:
    
    The short name or full Amazon Resource Name (ARN) of the AWS Identity and Access Management (IAM) role that grants containers in the task permission to call AWS APIs on your behalf. For more information, see Amazon ECS Task Role in the Amazon Elastic Container Service Developer Guide.
    
    IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code in order to take advantage of the feature. For more information, see Windows IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide.
  - executionRoleArn
```
public String executionRoleArn()
```
    The Amazon Resource Name (ARN) of the task execution role that containers in this task can assume. All containers in this task are granted the permissions that are specified in this role.
    
    Returns:
    
    The Amazon Resource Name (ARN) of the task execution role that containers in this task can assume. All containers in this task are granted the permissions that are specified in this role.
  - networkMode
```
public NetworkMode networkMode()
```
    The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. The default Docker network mode is bridge. If you are using the Fargate launch type, the awsvpc network mode is required. If you are using the EC2 launch type, any network mode can be used. If the network mode is set to none, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.
    
    With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.
    
    If the network mode is awsvpc, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.
    
    Currently, only Amazon ECS-optimized AMIs, other Amazon Linux variants with the ecs-init package, or AWS Fargate infrastructure support the awsvpc network mode.
    
    If the network mode is host, you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.
    
    Docker for Windows uses different network modes than Docker for Linux. When you register a task definition with Windows containers, you must not specify a network mode. If you use the console to register a task definition with Windows containers, you must choose the <default> network mode object.
    
    For more information, see Network settings in the Docker run reference.
    
    If the service returns an enum value that is not available in the current SDK version, networkMode will return NetworkMode.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from networkModeAsString().
    
    Returns:
    
    The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. The default Docker network mode is bridge. If you are using the Fargate launch type, the awsvpc network mode is required. If you are using the EC2 launch type, any network mode can be used. If the network mode is set to none, you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity.

    The IPC resource namespace to use for the containers in the task. The valid values are host, task, or none. If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference.
    
    If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security.
    
    If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide.
    - For tasks that use the host IPC mode, IPC namespace related systemControls are not supported.
    - For tasks that use the task IPC mode, IPC namespace related systemControls will apply to all containers within a task.
    This parameter is not supported for Windows containers or tasks using the Fargate launch type.
    
    If the service returns an enum value that is not available in the current SDK version, ipcMode will return IpcMode.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from ipcModeAsString().
    Returns:
    The IPC resource namespace to use for the containers in the task. The valid values are host, task, or none. If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance.
