Example:

         .memoryMiB("512")
         .cpu("256")
         .compatibility(Compatibility.FARGATE)
         .build();
 ContainerDefinition containerDefinition = taskDefinition.addContainer("TheContainer", ContainerDefinitionOptions.builder()
         .image(ContainerImage.fromRegistry("foo/bar"))

  • Method Details

    • getCompatibility

      @Stability(Stable) @NotNull Compatibility getCompatibility()
      The task launch type compatiblity requirement.
    • getCpu

      @Stability(Stable) @Nullable default String getCpu()
      The number of cpu units used by the task.

      If you are using the EC2 launch type, this field is optional and any value can be used. If you are 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)

      8192 (8 vCPU) - Available memory values: Between 16384 (16 GB) and 61440 (60 GB) in increments of 4096 (4 GB)

      16384 (16 vCPU) - Available memory values: Between 32768 (32 GB) and 122880 (120 GB) in increments of 8192 (8 GB)

      Default: - CPU units are not specified.

    • getEphemeralStorageGiB

      @Stability(Stable) @Nullable default Number getEphemeralStorageGiB()
      The amount (in GiB) of ephemeral storage to be allocated to the task.

      Only supported in Fargate platform version 1.4.0 or later.

      Default: - Undefined, in which case, the task will receive 20GiB ephemeral storage.

    • getInferenceAccelerators

      @Stability(Stable) @Nullable default List<InferenceAccelerator> getInferenceAccelerators()
      The inference accelerators to use for the containers in the task.

      Not supported in Fargate.

      Default: - No inference accelerators.

    • getIpcMode

      @Stability(Stable) @Nullable default IpcMode getIpcMode()
      The IPC resource namespace to use for the containers in the task.

      Not supported in Fargate and Windows containers.

      Default: - IpcMode used by the task is not specified

    • getMemoryMiB

      @Stability(Stable) @Nullable default String getMemoryMiB()
      The amount (in MiB) of memory used by the task.

      If using the EC2 launch type, this field is optional and any value can be used. If 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:
