    • maxvCpus

      @Stability(Stable) public CfnComputeEnvironment.ComputeResourcesProperty.Builder maxvCpus(Number maxvCpus)
      Sets the value of CfnComputeEnvironment.ComputeResourcesProperty.getMaxvCpus()
      Parameters:
      maxvCpus - The maximum number of Amazon EC2 vCPUs that an environment can reach. This parameter is required.

      With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED allocation strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, AWS Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, AWS Batch never exceeds maxvCpus by more than a single instance. That is, no more than a single instance from among those specified in your compute environment.

      Returns:
      this

    • subnets

      @Stability(Stable) public CfnComputeEnvironment.ComputeResourcesProperty.Builder subnets(List<String> subnets)
      Sets the value of CfnComputeEnvironment.ComputeResourcesProperty.getSubnets()
      Parameters:
      subnets - The VPC subnets where the compute resources are launched. This parameter is required. Fargate compute resources can contain up to 16 subnets. For Fargate compute resources, providing an empty list will be handled as if this parameter wasn't specified and no change is made. For EC2 compute resources, providing an empty list removes the VPC subnets from the compute resource. For more information, see VPCs and subnets in the Amazon VPC User Guide .

      When updating a compute environment, changing the VPC subnets requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the AWS Batch User Guide .

      AWS Batch on Amazon EC2 and AWS Batch on Amazon EKS support Local Zones. For more information, see Local Zones in the Amazon EC2 User Guide for Linux Instances , Amazon EKS and AWS Local Zones in the Amazon EKS User Guide and Amazon ECS clusters in Local Zones, Wavelength Zones, and AWS Outposts in the Amazon ECS Developer Guide .

      AWS Batch on Fargate doesn't currently support Local Zones.

      Returns:
      this

    • type

      @Stability(Stable) public CfnComputeEnvironment.ComputeResourcesProperty.Builder type(String type)
      Sets the value of CfnComputeEnvironment.ComputeResourcesProperty.getType()
      Parameters:
      type - The type of compute environment: EC2 , SPOT , FARGATE , or FARGATE_SPOT . This parameter is required. For more information, see Compute environments in the AWS Batch User Guide .

      If you choose SPOT , you must also specify an Amazon EC2 Spot Fleet role with the spotIamFleetRole parameter. For more information, see Amazon EC2 spot fleet role in the AWS Batch User Guide .

      When updating compute environment, changing the type of a compute environment requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the AWS Batch User Guide .

      When updating the type of a compute environment, changing between EC2 and SPOT or between FARGATE and FARGATE_SPOT will initiate an infrastructure update, but if you switch between EC2 and FARGATE , AWS CloudFormation will create a new compute environment.

      Returns:
      this

    • allocationStrategy

      @Stability(Stable) public CfnComputeEnvironment.ComputeResourcesProperty.Builder allocationStrategy(String allocationStrategy)
      Sets the value of CfnComputeEnvironment.ComputeResourcesProperty.getAllocationStrategy()
      Parameters:
      allocationStrategy - The allocation strategy to use for the compute resource if not enough instances of the best fitting instance type can be allocated. This might be because of availability of the instance type in the Region or Amazon EC2 service limits . For more information, see Allocation strategies in the AWS Batch User Guide .

      When updating a compute environment, changing the allocation strategy requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the AWS Batch User Guide . BEST_FIT is not supported when updating a compute environment.

      This parameter isn't applicable to jobs that are running on Fargate resources, and shouldn't be specified.

      • BEST_FIT (default) - AWS Batch selects an instance type that best fits the needs of the jobs with a preference for the lowest-cost instance type. If additional instances of the selected instance type aren't available, AWS Batch waits for the additional instances to be available. If there aren't enough instances available, or if the user is reaching Amazon EC2 service limits then additional jobs aren't run until the currently running jobs have completed. This allocation strategy keeps costs lower but can limit scaling. If you are using Spot Fleets with BEST_FIT then the Spot Fleet IAM role must be specified.
      • BEST_FIT_PROGRESSIVE - AWS Batch will select additional instance types that are large enough to meet the requirements of the jobs in the queue, with a preference for instance types with a lower cost per unit vCPU. If additional instances of the previously selected instance types aren't available, AWS Batch will select new instance types.
      • SPOT_CAPACITY_OPTIMIZED - AWS Batch will select one or more instance types that are large enough to meet the requirements of the jobs in the queue, with a preference for instance types that are less likely to be interrupted. This allocation strategy is only available for Spot Instance compute resources.

      With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED allocation strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, AWS Batch might need to go above maxvCpus to meet your capacity requirements. In this event, AWS Batch never exceeds maxvCpus by more than a single instance.

      Returns:
      this

    • bidPercentage

      @Stability(Stable) public CfnComputeEnvironment.ComputeResourcesProperty.Builder bidPercentage(Number bidPercentage)
      Sets the value of CfnComputeEnvironment.ComputeResourcesProperty.getBidPercentage()
      Parameters:
      bidPercentage - The maximum percentage that a Spot Instance price can be when compared with the On-Demand price for that instance type before instances are launched. For example, if your maximum percentage is 20%, the Spot price must be less than 20% of the current On-Demand price for that Amazon EC2 instance. You always pay the lowest (market) price and never more than your maximum percentage. For most use cases, we recommend leaving this field empty.

      When updating a compute environment, changing the bid percentage requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the AWS Batch User Guide .

      This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

      Returns:
      this

    • desiredvCpus

      @Stability(Stable) public CfnComputeEnvironment.ComputeResourcesProperty.Builder desiredvCpus(Number desiredvCpus)

      Parameters:
      desiredvCpus - The desired number of vCPUS in the compute environment. AWS Batch modifies this value between the minimum and maximum values based on job queue demand.

      This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it. > AWS Batch doesn't support changing the desired number of vCPUs of an existing compute environment. Don't specify this parameter for compute environments using Amazon EKS clusters. > When you update the desiredvCpus setting, the value must be between the minvCpus and maxvCpus values.

      Additionally, the updated desiredvCpus value must be greater than or equal to the current desiredvCpus value. For more information, see Troubleshooting AWS Batch in the AWS Batch User Guide .

      Returns:
      this
