## Properties

- `containerDefinitions`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnDaemonTaskDefinition.DaemonContainerDefinitionProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_ecs.CfnDaemonTaskDefinition.DaemonContainerDefinitionProperty.html)[] — A list of container definitions in JSON format that describe the containers that make up the daemon task.

- `cpu`: string — The number of CPU units used by the daemon task.

- `executionRoleArn`: string — 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.

- `family`: string — The name of a family that this daemon task definition is registered to.

- `ipcMode`: string — The IPC namespace mode for the daemon.

  The valid values are ``none`` and ``shared``. The default is ``none``.
   If ``none`` is specified or no value is provided, the daemon runs with its own IPC namespace, isolated from other tasks. If ``shared`` is specified, the daemon joins the host IPC namespace, making it accessible to non-daemon tasks that use ``ipcMode: "host"`` or other daemons that use ``ipcMode: "shared"``.

- `memory`: string — The amount of memory (in MiB) used by the daemon task.

- `pidMode`: string — The PID namespace mode for the daemon.

  The valid values are ``none`` and ``shared``. The default is ``none``.
   If ``none`` is specified or no value is provided, the daemon runs with its own PID namespace, isolated from other tasks. If ``shared`` is specified, the daemon joins the host PID namespace, making it accessible to non-daemon tasks that use ``pidMode: "host"`` or other daemons that use ``pidMode: "shared"``.

- `tags`: [CfnTag](/cdk/api/v2/docs/aws-cdk-lib.CfnTag.html)[]

- `taskRoleArn`: string — The short name or full Amazon Resource Name (ARN) of the IAM role that grants containers in the daemon task permission to call Amazon Web Services APIs on your behalf.

- `volumes`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnDaemonTaskDefinition.VolumeProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_ecs.CfnDaemonTaskDefinition.VolumeProperty.html)[] — The list of data volume definitions for the daemon task.
