  • cpu (Union[int, float, None]) – The number of cpu units used by the task. Valid values, which determines your range of valid values for the memory parameter: 256 (.25 vCPU) - Available memory values: 0.5GB, 1GB, 2GB 512 (.5 vCPU) - Available memory values: 1GB, 2GB, 3GB, 4GB 1024 (1 vCPU) - Available memory values: 2GB, 3GB, 4GB, 5GB, 6GB, 7GB, 8GB 2048 (2 vCPU) - Available memory values: Between 4GB and 16GB in 1GB increments 4096 (4 vCPU) - Available memory values: Between 8GB and 30GB in 1GB increments This default is set in the underlying FargateTaskDefinition construct.

  • memory_reservation_mib (Union[int, float, None]) – The soft limit (in MiB) of memory to reserve for the container. When system memory is under contention, Docker attempts to keep the container memory within the limit. If the container requires more memory, it can consume up to the value specified by the Memory property or all of the available memory on the container instance—whichever comes first. At least one of memoryLimitMiB and memoryReservationMiB is required. Default: - No memory reserved.
