Parameters

Name	Description
id Required	str 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 IDs within an Account that differ only by case).
display_name Required	str The display name need not be unique and can contain any Unicode characters up to a maximum length of 1024.
url Required	str
e_tag Required	str This is an opaque string. You can use it to detect whether the Pool has changed between requests. In particular, you can be pass the ETag when updating a Pool to specify that your changes should take effect only if nobody else has modified the Pool in the meantime.
last_modified Required	datetime This is the last time at which the Pool level data, such as the targetDedicatedNodes or enableAutoscale settings, changed. It does not factor in node-level changes such as a Compute Node changing state.
creation_time Required	datetime
state Required	str or PoolState Possible values include: 'active', 'deleting'
state_transition_time Required	datetime
allocation_state Required	str or AllocationState Possible values include: 'steady', 'resizing', 'stopping'
allocation_state_transition_time Required	datetime
vm_size Required	str For information about available sizes of virtual machines in Pools, see Choose a VM size for Compute Nodes in an Azure Batch Pool (https://docs.microsoft.com/azure/batch/batch-pool-vm-sizes).
cloud_service_configuration Required	CloudServiceConfiguration The cloud service configuration for the Pool. This property and virtualMachineConfiguration are mutually exclusive and one of the properties must be specified. This property cannot be specified if the Batch Account was created with its poolAllocationMode property set to 'UserSubscription'.
virtual_machine_configuration Required	VirtualMachineConfiguration The virtual machine configuration for the Pool. This property and cloudServiceConfiguration are mutually exclusive and one of the properties must be specified.
resize_timeout Required	<xref:timedelta> This is the timeout for the most recent resize operation. (The initial sizing when the Pool is created counts as a resize.) The default value is 15 minutes.
resize_errors Required	list[ResizeError] This property is set only if one or more errors occurred during the last Pool resize, and only when the Pool allocationState is Steady.
current_dedicated_nodes Required	int The number of dedicated Compute Nodes currently in the Pool.
current_low_priority_nodes Required	int The number of Spot/Low-priority Compute Nodes currently in the Pool. Spot/Low-priority Compute Nodes which have been preempted are included in this count.
target_dedicated_nodes Required	int The desired number of dedicated Compute Nodes in the Pool.
target_low_priority_nodes Required	int The desired number of Spot/Low-priority Compute Nodes in the Pool.
enable_auto_scale Required	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 Required	str This property is set only if the Pool automatically scales, i.e. enableAutoScale is true.
auto_scale_evaluation_interval Required	<xref:timedelta> This property is set only if the Pool automatically scales, i.e. enableAutoScale is true.
auto_scale_run Required	AutoScaleRun The results and errors from the last execution of the autoscale formula. This property is set only if the Pool automatically scales, i.e. enableAutoScale is true.
enable_inter_node_communication Required	bool Whether the Pool permits direct communication between Compute Nodes. This imposes restrictions on which Compute Nodes can be assigned to the Pool. Specifying this value can reduce the chance of the requested number of Compute Nodes to be allocated in the Pool.
network_configuration Required	NetworkConfiguration The network configuration for the Pool.
start_task Required	StartTask A Task specified to run on each Compute Node as it joins the Pool.
certificate_references Required	list[CertificateReference] For Windows Nodes, the Batch service installs the Certificates to the specified Certificate store and location. For Linux Compute Nodes, the Certificates are stored in a directory inside the Task working directory and an environment variable AZ_BATCH_CERTIFICATES_DIR is supplied to the Task to query for this location. For Certificates with visibility of 'remoteUser', a 'certs' directory is created in the user's home directory (e.g., /home/{user-name}/certs) and Certificates are placed in that directory. Warning: This property is deprecated and will be removed after February, 2024. Please use the Azure KeyVault Extension instead.
application_package_references Required	list[ApplicationPackageReference] 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.
application_licenses Required	list[str] The list of application licenses must be a subset of available Batch service application licenses. If a license is requested which is not supported, Pool creation will fail.
task_slots_per_node Required	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 Required	TaskSchedulingPolicy How Tasks are distributed across Compute Nodes in a Pool. If not specified, the default is spread.
user_accounts Required	list[UserAccount]
metadata Required	list[MetadataItem]
stats Required	PoolStatistics Utilization and resource usage statistics for the entire lifetime of the Pool. This property is populated only if the CloudPool was retrieved with an expand clause including the 'stats' attribute; otherwise it is null. The statistics may not be immediately available. The Batch service performs periodic roll-up of statistics. The typical delay is about 30 minutes.
mount_configuration Required	list[MountConfiguration] This supports Azure Files, NFS, CIFS/SMB, and Blobfuse.
identity Required	BatchPoolIdentity The identity of the Batch pool, if configured. The list of user identities associated with the Batch pool. The user identity dictionary key references will be ARM resource ids in the form: '/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.ManagedIdentity/userAssignedIdentities/{identityName}'.
target_node_communication_mode Required	str or NodeCommunicationMode The desired node communication mode for the pool. If omitted, the default value is Default. Possible values include: 'default', 'classic', 'simplified'
upgrade_policy Required	UpgradePolicy The upgrade policy for the Pool. Describes an upgrade policy - automatic, manual, or rolling.
resource_tags Required	dict[str, str] The user-defined tags to be associated with the Azure Batch Pool. When specified, these tags are propagated to the backing Azure resources associated with the pool. This property can only be specified when the Batch account was created with the poolAllocationMode property set to 'UserSubscription'.

Methods

as_dict	Return a dict that can be JSONify using json.dump. Advanced usage might optionally use a callback as parameter: Key is the attribute name used in Python. Attr_desc is a dict of metadata. Currently contains 'type' with the msrest type and 'key' with the RestAPI encoded key. Value is the current value in this object. The string returned will be used to serialize the key. If the return type is a list, this is considered hierarchical result dict. See the three examples in this file: attribute_transformer full_restapi_key_transformer last_restapi_key_transformer If you want XML serialization, you can pass the kwargs is_xml=True.
deserialize	Parse a str using the RestAPI syntax and return a model.
enable_additional_properties_sending
from_dict	Parse a dict using given key extractor return a model. By default consider key extractors (rest_key_case_insensitive_extractor, attribute_key_case_insensitive_extractor and last_rest_key_case_insensitive_extractor)
is_xml_model
serialize	Return the JSON that would be sent to azure from this model. This is an alias to as_dict(full_restapi_key_transformer, keep_readonly=False). If you want XML serialization, you can pass the kwargs is_xml=True.
validate	Validate this model recursively and return a list of ValidationError.
