Description

Registers a new task definition from the supplied family and containerDefinitions. Optionally, you can add data volumes to your containers with the volumes parameter. For more information about task definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide. You can specify a role for your task with the taskRoleArn parameter. When you specify a role for a task, its containers can then use the latest versions of the CLI or SDKs to make API requests to the Amazon Web Services services that are specified in the policy that's associated with the role. For more information, see IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide. You can specify a Docker networking mode for the containers in your task definition with the networkMode parameter. If you specify the awsvpc network mode, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration 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.

Parameters

-ClientConfig <AmazonECSConfig>
Amazon.PowerShell.Cmdlets.ECS.AmazonECSClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ContainerDefinition <ContainerDefinition[]>
A list of container definitions in JSON format that describe the different containers that make up your task. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesContainerDefinitions
-Cpu <String>
The number of CPU units used by the task. It can be expressed as an integer using CPU units (for example, 1024) or as a string using vCPUs (for example, 1 vCPU or 1 vcpu) in a task definition. String values are converted to an integer indicating the CPU units when the task definition is registered.Task-level CPU and memory parameters are ignored for Windows containers. We recommend specifying container-level resources for Windows containers.If you're using the EC2 launch type or external launch type, this field is optional. Supported values are between 128 CPU units (0.125 vCPUs) and 196608 CPU units (192 vCPUs). If you do not specify a value, the parameter is ignored.This field is required for Fargate. For information about the valid values, see Task size in the Amazon Elastic Container Service Developer Guide.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. For informationabout the required IAM roles for Amazon ECS, see IAM roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Family <String>
You must specify a family for a task definition. You can use it track multiple versions of the same task definition. The family is used as a name for your task definition. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.
Required?True

Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-InferenceAccelerator <InferenceAccelerator[]>
The Elastic Inference accelerators to use for the containers in the task. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesInferenceAccelerators
-IpcMode <IpcMode>
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.If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose.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 run on Fargate.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Memory <String>
The amount of memory (in MiB) used by the task. It can be expressed as an integer using MiB (for example ,1024) or as a string using GB (for example, 1GB or 1 GB) in a task definition. String values are converted to an integer indicating the MiB when the task definition is registered.Task-level CPU and memory parameters are ignored for Windows containers. We recommend specifying container-level resources for Windows containers.If using the EC2 launch type, this field is optional.If using the Fargate launch type, this field is required and you must use one of the following values. This determines your range of supported values for the cpu parameter.The CPU units cannot be less than 1 vCPU when you use Windows containers on Fargate.
  • 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) - Available cpu values: 256 (.25 vCPU)
  • 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) - Available cpu values: 512 (.5 vCPU)
  • 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB) - Available cpu values: 1024 (1 vCPU)
  • Between 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) - Available cpu values: 2048 (2 vCPU)
  • Between 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) - Available cpu values: 4096 (4 vCPU)
  • Between 16 GB and 60 GB in 4 GB increments - Available cpu values: 8192 (8 vCPU)This option requires Linux platform 1.4.0 or later.
  • Between 32GB and 120 GB in 8 GB increments - Available cpu values: 16384 (16 vCPU)This option requires Linux platform 1.4.0 or later.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkMode <NetworkMode>
The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. If no network mode is specified, the default is bridge.For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc 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. When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.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.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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PidMode <PidMode>
The process namespace to use for the containers in the task. The valid values are host or task. On Fargate for Linux containers, the only valid value is 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 same 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 The default is a private namespace for each container.If the host PID mode is used, there's a heightened risk of undesired process namespace exposure.This parameter is not supported for Windows containers.This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PlacementConstraint <TaskDefinitionPlacementConstraint[]>
An array of placement constraint objects to use for the task. You can specify a maximum of 10 constraints for each task. This limit includes constraints in the task definition and those specified at runtime. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
