BatchPoolCreateOptions Class

Parameters for creating an Azure Batch Pool.

Constructor

BatchPoolCreateOptions(*args: Any, **kwargs: Any)

Variables

Name	Description
id	str A string that uniquely identifies the Pool within the Account. The ID can contain any combination of alphanumeric characters including hyphens and underscores, and cannot contain more than 64 characters. The ID is case-preserving and case-insensitive (that is, you may not have two Pool IDs within an Account that differ only by case). Required.
display_name	str The display name for the Pool. The display name need not be unique and can contain any Unicode characters up to a maximum length of 1024.
vm_size	str The size of virtual machines in the Pool. All virtual machines in a Pool are the same size. For information about available VM sizes for Pools using Images from the Virtual Machines Marketplace (pools created with virtualMachineConfiguration), see Sizes for Virtual Machines in Azure (https://learn.microsoft.com/azure/virtual-machines/sizes/overview). Batch supports all Azure VM sizes except STANDARD_A0 and those with premium storage (STANDARD_GS, STANDARD_DS, and STANDARD_DSV2 series). Required.
virtual_machine_configuration	VirtualMachineConfiguration The virtual machine configuration for the Pool. This property must be specified.
resize_timeout	timedelta The timeout for allocation of Compute Nodes to the Pool. This timeout applies only to manual scaling; it has no effect when enableAutoScale is set to true. The default value is 15 minutes. The minimum value is 5 minutes. If you specify a value less than 5 minutes, the Batch service returns an error; if you are calling the REST API directly, the HTTP status code is 400 (Bad Request). The time duration is specified in ISO 8601 format.
target_dedicated_nodes	int The desired number of dedicated Compute Nodes in the Pool. This property must not be specified if enableAutoScale is set to true. If enableAutoScale is set to false, then you must set either targetDedicatedNodes, targetLowPriorityNodes, or both.
target_low_priority_nodes	int The desired number of Spot/Low-priority Compute Nodes in the Pool. This property must not be specified if enableAutoScale is set to true. If enableAutoScale is set to false, then you must set either targetDedicatedNodes, targetLowPriorityNodes, or both.
enable_auto_scale	bool Whether the Pool size should automatically adjust over time. If false, at least one of targetDedicatedNodes and targetLowPriorityNodes must be specified. If true, the autoScaleFormula property is required and the Pool automatically resizes according to the formula. The default value is false.
auto_scale_formula	str A formula for the desired number of Compute Nodes in the Pool. This property must not be specified if enableAutoScale is set to false. It is required if enableAutoScale is set to true. The formula is checked for validity before the Pool is created. If the formula is not valid, the Batch service rejects the request with detailed error information. For more information about specifying this formula, see 'Automatically scale Compute Nodes in an Azure Batch Pool' (https://learn.microsoft.com/azure/batch/batch-automatic-scaling).
auto_scale_evaluation_interval	timedelta The time interval at which to automatically adjust the Pool size according to the autoscale formula. The default value is 15 minutes. The minimum and maximum value are 5 minutes and 168 hours respectively. If you specify a value less than 5 minutes or greater than 168 hours, the Batch service returns an error; if you are calling the REST API directly, the HTTP status code is 400 (Bad Request). The time duration is specified in ISO 8601 format.
enable_inter_node_communication	bool Whether the Pool permits direct communication between Compute Nodes. Enabling inter-node communication limits the maximum size of the Pool due to deployment restrictions on the Compute Nodes of the Pool. This may result in the Pool not reaching its desired size. The default value is false.
network_configuration	NetworkConfiguration The network configuration for the Pool.
start_task	BatchStartTask A Task specified to run on each Compute Node as it joins the Pool. The Task runs when the Compute Node is added to the Pool or when the Compute Node is restarted.
application_package_references	list[BatchApplicationPackageReference] The list of Packages to be installed on each Compute Node in the Pool. When creating a pool, the package's application ID must be fully qualified (/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Batch/batchAccounts/{accountName}/applications/{applicationName}). Changes to Package references affect all new Nodes joining the Pool, but do not affect Compute Nodes that are already in the Pool until they are rebooted or reimaged. There is a maximum of 10 Package references on any given Pool.
task_slots_per_node	int The number of task slots that can be used to run concurrent tasks on a single compute node in the pool. The default value is 1. The maximum value is the smaller of 4 times the number of cores of the vmSize of the pool or 256.
task_scheduling_policy	BatchTaskSchedulingPolicy How Tasks are distributed across Compute Nodes in a Pool. If not specified, the default is spread.
user_accounts	list[UserAccount] The list of user Accounts to be created on each Compute Node in the Pool.
metadata	list[BatchMetadataItem] A list of name-value pairs associated with the Pool as metadata. The Batch service does not assign any meaning to metadata; it is solely for the use of user code.
mount_configuration	list[MountConfiguration] Mount storage using specified file system for the entire lifetime of the pool. Mount the storage using Azure fileshare, NFS, CIFS or Blobfuse based file system.
upgrade_policy	UpgradePolicy The upgrade policy for the Pool. Describes an upgrade policy - automatic, manual, or rolling.
