    • 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.

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

      If the service returns an enum value that is not available in the current SDK version, networkMode will return NetworkMode.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from networkModeAsString().

      Returns: 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.

      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.

    • hasInferenceAccelerators

      public final boolean hasInferenceAccelerators()

      For responses, this returns true if the service returned a value for the InferenceAccelerators property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • inferenceAccelerators

      The Elastic Inference accelerator that's associated with the task.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasInferenceAccelerators() method.

      Returns: The Elastic Inference accelerator that's associated with the task.

    • 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 default is a private namespace for each container. For more information, see PID settings in the Docker run reference.

      If the host PID mode is used, there's a heightened risk of undesired process namespace exposure. For more information, see Docker security.

      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.

      If the service returns an enum value that is not available in the current SDK version, pidMode will return PidMode.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from pidModeAsString().

      Returns: 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.

    • 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. 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 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.
