#ipc_modeString

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][3

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.

<note markdown=“1”> This parameter is not supported for Windows containers or tasks run on Fargate.

#memoryString

The amount (in MiB) of memory used by the task.

If your tasks runs on Amazon EC2 instances, you must specify either a task-level memory value or a container-level memory value. This field is optional and any value can be used. If a task-level memory value is specified, the container-level memory value is optional. For more information regarding container-level memory and memory reservation, see [ContainerDefinition].

If your tasks runs on Fargate, this field is required. You must use one of the following values. The value you choose determines your range of valid values for the `cpu` parameter.

  • 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)

#network_modeString

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.

For more information, see [Network settings] in the *Docker run reference*.

The process namespace to use for the containers in the task. The valid values are `host` or `task`.

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 more information, see [PID settings] in the *Docker run reference*.

If the `host` PID mode is used, be aware that there is a heightened risk of undesired process namespace expose. For more information, see [Docker security].

#proxy_configurationTypes::ProxyConfiguration

The configuration details for the App Mesh proxy.

Your Amazon ECS container instances require at least version 1.26.0 of the container agent and at least version 1.26.0-1 of the `ecs-init` package to enable a proxy configuration. If your container instances are launched from the Amazon ECS optimized AMI version `20190301` or later, they contain the required versions of the container agent and `ecs-init`. For more information, see

Amazon ECS-optimized Linux AMI][1

in the *Amazon Elastic Container

Service Developer Guide*.

#requires_attributesArray<Types::Attribute>

The container instance attributes required by your task. When an Amazon EC2 instance is registered to your cluster, the Amazon ECS container agent assigns some standard attributes to the instance. You can apply custom attributes. These are specified as key-value pairs using the Amazon ECS console or the PutAttributes API. These attributes are used when determining task placement for tasks hosted on Amazon EC2 instances. For more information, see [Attributes] in the *Amazon Elastic Container Service Developer Guide*.

<note markdown=“1”> This parameter isn't supported for tasks run on Fargate.

#revisionInteger

The revision of the task in a particular family. The revision is a version number of a task definition in a family. When you register a task definition for the first time, the revision is `1`. Each time that you register a new revision of a task definition in the same family, the revision value always increases by one. This is even if you deregistered previous revisions in this family.

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 to use the feature. For more information, see [Windows IAM roles for tasks] in the *Amazon Elastic Container Service Developer Guide*.
