      • taskRoleArn

        public final String taskRoleArn()

        The short name or full Amazon Resource Name (ARN) of the IAM role that containers in this task can assume. All containers in this task are granted the permissions that are specified in this role. For more information, see IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide.

        Returns:
        The short name or full Amazon Resource Name (ARN) of the IAM role that containers in this task can assume. All containers in this task are granted the permissions that are specified in this role. For more information, see IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide.

      • executionRoleArn

        public final String executionRoleArn()

        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.

        Returns:
        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.

      • networkMode

        public final 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.

        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.

      • tags

        public final List<Tag> tags()

        The metadata that you apply to the task definition to help you categorize and organize them. Each tag consists of a key and an optional value. You define both of them.

        The following basic restrictions apply to tags:

        • Maximum number of tags per resource - 50

        • For each resource, each tag key must be unique, and each tag key can have only one value.

        • Maximum key length - 128 Unicode characters in UTF-8

        • Maximum value length - 256 Unicode characters in UTF-8

        • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

        • Tag keys and values are case-sensitive.

        • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

        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 hasTags() method.

        Returns:

      • pidMode

        public final 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 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.

        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.

        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.

        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.

      • ipcMode

        public final 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.

      • proxyConfiguration

        public final ProxyConfiguration proxyConfiguration()

        The configuration details for the App Mesh proxy.

        For tasks hosted on Amazon EC2 instances, the 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, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized AMI versions in the Amazon Elastic Container Service Developer Guide.

      • 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

        public final List<InferenceAccelerator> inferenceAccelerators()

        The Elastic Inference accelerators to use for the containers in 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 accelerators to use for the containers in the task.

      • ephemeralStorage

        public final EphemeralStorage ephemeralStorage()

        The amount of ephemeral storage to allocate for the task. This parameter is used to expand the total amount of ephemeral storage available, beyond the default amount, for tasks hosted on Fargate. For more information, see Using data volumes in tasks in the Amazon ECS Developer Guide.

        For tasks using the Fargate launch type, the task requires the following platforms:

        • Linux platform version 1.4.0 or later.

        • Windows platform version 1.0.0 or later.

        Returns:
        The amount of ephemeral storage to allocate for the task. This parameter is used to expand the total amount of ephemeral storage available, beyond the default amount, for tasks hosted on Fargate. For more information, see Using data volumes in tasks in the Amazon ECS Developer Guide.
