## Properties
<a name="aws-properties-batch-jobdefinition-ecstaskproperties-properties"></a>

`Containers`  <a name="cfn-batch-jobdefinition-ecstaskproperties-containers"></a>
This object is a list of containers.  
*Required*: No  
*Type*: Array of [TaskContainerProperties](aws-properties-batch-jobdefinition-taskcontainerproperties.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`EnableExecuteCommand`  <a name="cfn-batch-jobdefinition-ecstaskproperties-enableexecutecommand"></a>
Determines whether execute command functionality is turned on for this task. If `true`, execute command functionality is turned on all the containers in the task.  
*Required*: No  
*Type*: Boolean  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`EphemeralStorage`  <a name="cfn-batch-jobdefinition-ecstaskproperties-ephemeralstorage"></a>
The amount of ephemeral storage to allocate for the task. This parameter is used to expand the total amount of ephemeral storage available, beyond the default amount, for tasks hosted on AWS Fargate.  
*Required*: No  
*Type*: [EphemeralStorage](aws-properties-batch-jobdefinition-ephemeralstorage.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`ExecutionRoleArn`  <a name="cfn-batch-jobdefinition-ecstaskproperties-executionrolearn"></a>
The Amazon Resource Name (ARN) of the execution role that AWS Batch can assume. For jobs that run on Fargate resources, you must provide an execution role. For more information, see [AWS Batch execution IAM role](https://docs.aws.amazon.com/batch/latest/userguide/execution-IAM-role.html) in the *AWS Batch User Guide*.  
*Required*: No  
*Type*: String  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`IpcMode`  <a name="cfn-batch-jobdefinition-ecstaskproperties-ipcmode"></a>
The IPC resource namespace to use for the containers in the task. The valid values are `host`, `task`, or `none`.  
If `host` is specified, 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, the IPC resources within the containers of a task are private, and are 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](https://docs.docker.com/engine/reference/run/#ipc-settings---ipc) in the Docker run reference.  
*Required*: No  
*Type*: String  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`NetworkConfiguration`  <a name="cfn-batch-jobdefinition-ecstaskproperties-networkconfiguration"></a>
The network configuration for jobs that are running on Fargate resources. Jobs that are running on Amazon EC2 resources must not specify this parameter.  
*Required*: No  
*Type*: [NetworkConfiguration](aws-properties-batch-jobdefinition-networkconfiguration.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`PidMode`  <a name="cfn-batch-jobdefinition-ecstaskproperties-pidmode"></a>
The process namespace to use for the containers in the task. The valid values are `host` or `task`. For example, monitoring sidecars might need `pidMode` to access information about other containers running in the same task.  
If `host` is specified, all containers within the tasks that specified the `host` PID mode on the same container instance share the process namespace with the host Amazon EC2 instance.  
If `task` is specified, all containers within the specified task share the same process namespace.  
If no value is specified, the default is a private namespace for each container. For more information, see [PID settings](https://docs.docker.com/engine/reference/run/#pid-settings---pid) in the Docker run reference.  
*Required*: No  
*Type*: String  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`PlatformVersion`  <a name="cfn-batch-jobdefinition-ecstaskproperties-platformversion"></a>
The Fargate platform version where the jobs are running. A platform version is specified only for jobs that are running on Fargate resources. If one isn't specified, the `LATEST` platform version is used by default. This uses a recent, approved version of the Fargate platform for compute resources. For more information, see [AWS Fargate platform versions](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/platform_versions.html) in the *Amazon Elastic Container Service Developer Guide*.  
*Required*: No  
*Type*: String

`RuntimePlatform`  <a name="cfn-batch-jobdefinition-ecstaskproperties-runtimeplatform"></a>
An object that represents the compute environment architecture for AWS Batch jobs on Fargate.  
*Required*: No  
*Type*: [RuntimePlatform](aws-properties-batch-jobdefinition-runtimeplatform.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`TaskRoleArn`  <a name="cfn-batch-jobdefinition-ecstaskproperties-taskrolearn"></a>
The Amazon Resource Name (ARN) that's associated with the Amazon ECS task.  
This is object is comparable to [ContainerProperties:jobRoleArn](https://docs.aws.amazon.com/batch/latest/APIReference/API_ContainerProperties.html).
*Required*: No  
*Type*: String  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

A list of volumes that are associated with the job.  
*Required*: No  
*Type*: Array of [Volume](aws-properties-batch-jobdefinition-volume.md)
