Overview

The details of a task definition which describes the container and volume definitions of an Amazon Elastic Container Service task. You can specify which Docker images to use, the required resources, and other configurations related to launching the task definition through an Amazon ECS service or task.

#cpuString

The number of ‘cpu` units used by the task. If you use the EC2 launch type, this field is optional. Any value can be used. If you use the Fargate launch type, this field is required. You must use one of the following values. The value that you choose determines your range of valid values for the `memory` parameter.

If you use the EC2 launch type, this field is optional. Supported values are between ‘128` CPU units (`0.125` vCPUs) and `10240` CPU units (`10` vCPUs).

The CPU units cannot be less than 1 vCPU when you use Windows containers on Fargate.

  • 256 (.25 vCPU) - Available ‘memory` values: 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB)

  • 512 (.5 vCPU) - Available ‘memory` values: 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB)

  • 1024 (1 vCPU) - Available ‘memory` values: 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB)

  • 2048 (2 vCPU) - Available ‘memory` values: 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB)

  • 4096 (4 vCPU) - Available ‘memory` values: 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB)

  • 8192 (8 vCPU) - Available ‘memory` values: 16 GB and 60 GB in 4 GB increments

    This option requires Linux platform ‘1.4.0` or later.

  • 16384 (16vCPU) - Available ‘memory` values: 32GB and 120 GB in 8 GB increments

#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.

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][1

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)

  • 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.

#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.

#pid_modeString

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 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.

<note markdown=“1”> This parameter is not supported for Windows containers.

<note markdown=“1”> 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.

#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 use 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] 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][2

in the *Amazon Elastic Container Service Developer

Guide*.

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