Bases: aws_cdk.aws_ecs.CommonTaskDefinitionProps

The properties for a task definition.

Parameters

  • execution_role (Optional[IRole]) – The name of the IAM task execution role that grants the ECS agent to call AWS APIs on your behalf. The role will be used to retrieve container images from ECR and create CloudWatch log groups. Default: - An execution role will be automatically created if you use ECR images in your task definition.

  • family (Optional[str]) – The name of a family that this task definition is registered to. A family groups multiple versions of a task definition. Default: - Automatically generated name.

  • proxy_configuration (Optional[ProxyConfiguration]) – The configuration details for the App Mesh proxy. Default: - No proxy configuration.

  • task_role (Optional[IRole]) – The name of the IAM role that grants containers in the task permission to call AWS APIs on your behalf. Default: - A task role is automatically created for you.

  • volumes (Optional[Sequence[Volume]]) – The list of volume definitions for the task. For more information, see Task Definition Parameter Volumes. Default: - No volumes are passed to the Docker daemon on a container instance.

  • cpu (Union[int, float, None]) – The number of cpu units used by the task. For tasks using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of valid values for the memory parameter: 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: Between 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) 4096 (4 vCPU) - Available memory values: Between 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) Default: 256

  • memory_limit_mib (Union[int, float, None]) – The amount (in MiB) of memory used by the task. For tasks using the Fargate launch type, this field is required and you must use one of the following values, which 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) Default: 512
