#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 but will be converted to an integer indicating the CPU units when the task definition is registered.
<note markdown=“1”> Task-level CPU and memory parameters are ignored for Windows containers. We recommend specifying container-level resources for Windows containers.
</note>
If using the EC2 launch type, this field is optional. Supported values are between ‘128` CPU units (`0.125` vCPUs) and `10240` CPU units (`10` vCPUs).
If using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of supported values for the ‘memory` parameter:
-
256 (.25 vCPU) - Available ‘memory` values: 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB)

#network_mode ⇒ String
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 using the Fargate launch type, the `awsvpc` network mode is required. If using the EC2 launch type, any network mode can be used. If the network mode is set to `none`, you can’t specify port mappings in your container definitions, and the task’s 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 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 can’t 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.
For more information, see [Network settings] in the *Docker run reference*.
