Name	Description	Value
name	The resource name	string Constraints: Min length = 1 Max length = 1 Pattern = `^[a-zA-Z0-9_-]+$` (required)
parent	In Bicep, you can specify the parent resource for a child resource. You only need to add this property when the child resource is declared outside of the parent resource. For more information, see Child resource outside parent resource.	Symbolic name for resource of type: batchAccounts
properties	The properties associated with the pool.	PoolProperties

NetworkConfiguration

Name	Description	Value
endpointConfiguration	Pool endpoint configuration is only supported on pools with the virtualMachineConfiguration property.	PoolEndpointConfiguration
subnetId	The virtual network must be in the same region and subscription as the Azure Batch account. The specified subnet should have enough free IP addresses to accommodate the number of nodes in the pool. If the subnet doesn't have enough free IP addresses, the pool will partially allocate compute nodes, and a resize error will occur. The 'MicrosoftAzureBatch' service principal must have the 'Classic Virtual Machine Contributor' Role-Based Access Control (RBAC) role for the specified VNet. The specified subnet must allow communication from the Azure Batch service to be able to schedule tasks on the compute nodes. This can be verified by checking if the specified VNet has any associated Network Security Groups (NSG). If communication to the compute nodes in the specified subnet is denied by an NSG, then the Batch service will set the state of the compute nodes to unusable. For pools created via virtualMachineConfiguration the Batch account must have poolAllocationMode userSubscription in order to use a VNet. If the specified VNet has any associated Network Security Groups (NSG), then a few reserved system ports must be enabled for inbound communication. For pools created with a virtual machine configuration, enable ports 29876 and 29877, as well as port 22 for Linux and port 3389 for Windows. For pools created with a cloud service configuration, enable ports 10100, 20100, and 30100. Also enable outbound connections to Azure Storage on port 443. For more details see: /azure/batch/batch-api-basics#virtual-network-vnet-and-firewall-configuration	string

NetworkSecurityGroupRule

Name	Description	Value
access	The action that should be taken for a specified IP address, subnet range or tag.	'Allow' 'Deny' (required)
priority	Priorities within a pool must be unique and are evaluated in order of priority. The lower the number the higher the priority. For example, rules could be specified with order numbers of 150, 250, and 350. The rule with the order number of 150 takes precedence over the rule that has an order of 250. Allowed priorities are 150 to 3500. If any reserved or duplicate values are provided the request fails with HTTP status code 400.	int (required)
sourceAddressPrefix	Valid values are a single IP address (i.e. 10.10.10.10), IP subnet (i.e. 192.168.1.0/24), default tag, or * (for all addresses). If any other values are provided the request fails with HTTP status code 400.	string (required)

OSDisk

Name	Description	Value
caching	Default value is none.	'None' 'ReadOnly' 'ReadWrite'

PoolEndpointConfiguration

Name	Description	Value

applicationPackages	Changes to application packages affect all new compute nodes joining the pool, but do not affect compute nodes that are already in the pool until they are rebooted or reimaged.	ApplicationPackageReference[]
certificates	For Windows compute 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.	CertificateReference[]
deploymentConfiguration	Using CloudServiceConfiguration specifies that the nodes should be creating using Azure Cloud Services (PaaS), while VirtualMachineConfiguration uses Azure Virtual Machines (IaaS).	DeploymentConfiguration
displayName	The display name need not be unique and can contain any Unicode characters up to a maximum length of 1024.	string
interNodeCommunication	This imposes restrictions on which nodes can be assigned to the pool. Enabling this value can reduce the chance of the requested number of nodes to be allocated in the pool. If not specified, this value defaults to 'Disabled'.	'Disabled' 'Enabled'
maxTasksPerNode	The maximum number of tasks that can run concurrently on a single compute node in the pool.	int
metadata	The Batch service does not assign any meaning to metadata; it is solely for the use of user code.	MetadataItem[]
networkConfiguration	The network configuration for a pool.	NetworkConfiguration
scaleSettings	Defines the desired size of the pool. This can either be 'fixedScale' where the requested targetDedicatedNodes is specified, or 'autoScale' which defines a formula which is periodically reevaluated. If this property is not specified, the pool will have a fixed scale with 0 targetDedicatedNodes.	ScaleSettings
startTask	In an PATCH (update) operation, this property can be set to an empty object to remove the start task from the pool.	StartTask
taskSchedulingPolicy	Specifies how tasks should be distributed across compute nodes.	TaskSchedulingPolicy
userAccounts	The list of user accounts to be created on each node in the pool.	UserAccount[]
vmSize	For information about available sizes of virtual machines for Cloud Services pools (pools created with cloudServiceConfiguration), see Sizes for Cloud Services (https://azure.microsoft.com/documentation/articles/cloud-services-sizes-specs/). Batch supports all Cloud Services VM sizes except ExtraSmall. For information about available VM sizes for pools using images from the Virtual Machines Marketplace (pools created with virtualMachineConfiguration) see Sizes for Virtual Machines (Linux) (https://azure.microsoft.com/documentation/articles/virtual-machines-linux-sizes/) or Sizes for Virtual Machines (Windows) (https://azure.microsoft.com/documentation/articles/virtual-machines-windows-sizes/). Batch supports all Azure VM sizes except STANDARD_A0 and those with premium storage (STANDARD_GS, STANDARD_DS, and STANDARD_DSV2 series).	string

ResourceFile

Name	Description	Value
blobSource	This URL must be readable using anonymous access; that is, the Batch service does not present any credentials when downloading the blob. There are two ways to get such a URL for a blob in Azure storage: include a Shared Access Signature (SAS) granting read permissions on the blob, or set the ACL for the blob or its container to allow public access.	string (required)
fileMode	This property applies only to files being downloaded to Linux compute nodes. It will be ignored if it is specified for a resourceFile which will be downloaded to a Windows node. If this property is not specified for a Linux node, then a default value of 0770 is applied to the file.	string
filePath	The location on the compute node to which to download the file, relative to the task's working directory.	string (required)

ScaleSettings

Name	Description	Value
autoScale	This property and fixedScale are mutually exclusive and one of the properties must be specified.	AutoScaleSettings
fixedScale	This property and autoScale are mutually exclusive and one of the properties must be specified.	FixedScaleSettings

StartTask

Name	Description	Value
commandLine	The command line does not run under a shell, and therefore cannot take advantage of shell features such as environment variable expansion. If you want to take advantage of such features, you should invoke the shell in the command line, for example using "cmd /c MyCommand" in Windows or "/bin/sh -c MyCommand" in Linux. Required if any other properties of the startTask are specified.	string
environmentSettings	A list of environment variable settings for the start task.	EnvironmentSetting[]
maxTaskRetryCount	The Batch service retries a task if its exit code is nonzero. Note that this value specifically controls the number of retries. The Batch service will try the task once, and may then retry up to this limit. For example, if the maximum retry count is 3, Batch tries the task up to 4 times (one initial try and 3 retries). If the maximum retry count is 0, the Batch service does not retry the task. If the maximum retry count is -1, the Batch service retries the task without limit.	int
resourceFiles	A list of files that the Batch service will download to the compute node before running the command line.	ResourceFile[]
userIdentity	If omitted, the task runs as a non-administrative user unique to the task.	UserIdentity
waitForSuccess	If true and the start task fails on a compute node, the Batch service retries the start task up to its maximum retry count (maxTaskRetryCount). If the task has still not completed successfully after all retries, then the Batch service marks the compute node unusable, and will not schedule tasks to it. This condition can be detected via the node state and scheduling error detail. If false, the Batch service will not wait for the start task to complete. In this case, other tasks can start executing on the compute node while the start task is still running; and even if the start task fails, new tasks will continue to be scheduled on the node. The default is false.	bool

TaskSchedulingPolicy

Name	Description	Value
nodeFillType	How tasks should be distributed across compute nodes.	'Pack' 'Spread' (required)

UserAccount

Name	Description	Value
dataDisks	This property must be specified if the compute nodes in the pool need to have empty data disks attached to them.	DataDisk[]
imageReference	A reference to an Azure Virtual Machines Marketplace image or the Azure Image resource of a custom Virtual Machine. To get the list of all imageReferences verified by Azure Batch, see the 'List supported node agent SKUs' operation.	ImageReference (required)
licenseType	This only applies to images that contain the Windows operating system, and should only be used when you hold valid on-premises licenses for the nodes which will be deployed. If omitted, no on-premises licensing discount is applied. Values are: Windows_Server - The on-premises license is for Windows Server. Windows_Client - The on-premises license is for Windows Client.	string
nodeAgentSkuId	The Batch node agent is a program that runs on each node in the pool, and provides the command-and-control interface between the node and the Batch service. There are different implementations of the node agent, known as SKUs, for different operating systems. You must specify a node agent SKU which matches the selected image reference. To get the list of supported node agent SKUs along with their list of verified image references, see the 'List supported node agent SKUs' operation.	string (required)

NetworkConfiguration

Name	Description	Value
endpointConfiguration	Pool endpoint configuration is only supported on pools with the virtualMachineConfiguration property.	PoolEndpointConfiguration
subnetId	The virtual network must be in the same region and subscription as the Azure Batch account. The specified subnet should have enough free IP addresses to accommodate the number of nodes in the pool. If the subnet doesn't have enough free IP addresses, the pool will partially allocate compute nodes, and a resize error will occur. The 'MicrosoftAzureBatch' service principal must have the 'Classic Virtual Machine Contributor' Role-Based Access Control (RBAC) role for the specified VNet. The specified subnet must allow communication from the Azure Batch service to be able to schedule tasks on the compute nodes. This can be verified by checking if the specified VNet has any associated Network Security Groups (NSG). If communication to the compute nodes in the specified subnet is denied by an NSG, then the Batch service will set the state of the compute nodes to unusable. For pools created via virtualMachineConfiguration the Batch account must have poolAllocationMode userSubscription in order to use a VNet. If the specified VNet has any associated Network Security Groups (NSG), then a few reserved system ports must be enabled for inbound communication. For pools created with a virtual machine configuration, enable ports 29876 and 29877, as well as port 22 for Linux and port 3389 for Windows. For pools created with a cloud service configuration, enable ports 10100, 20100, and 30100. Also enable outbound connections to Azure Storage on port 443. For more details see: /azure/batch/batch-api-basics#virtual-network-vnet-and-firewall-configuration	string

NetworkSecurityGroupRule

Name	Description	Value
access	The action that should be taken for a specified IP address, subnet range or tag.	'Allow' 'Deny' (required)
priority	Priorities within a pool must be unique and are evaluated in order of priority. The lower the number the higher the priority. For example, rules could be specified with order numbers of 150, 250, and 350. The rule with the order number of 150 takes precedence over the rule that has an order of 250. Allowed priorities are 150 to 3500. If any reserved or duplicate values are provided the request fails with HTTP status code 400.	int (required)
sourceAddressPrefix	Valid values are a single IP address (i.e. 10.10.10.10), IP subnet (i.e. 192.168.1.0/24), default tag, or * (for all addresses). If any other values are provided the request fails with HTTP status code 400.	string (required)

certificates	For Windows compute 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.	CertificateReference[]
deploymentConfiguration	Using CloudServiceConfiguration specifies that the nodes should be creating using Azure Cloud Services (PaaS), while VirtualMachineConfiguration uses Azure Virtual Machines (IaaS).	DeploymentConfiguration
displayName	The display name need not be unique and can contain any Unicode characters up to a maximum length of 1024.	string
interNodeCommunication	This imposes restrictions on which nodes can be assigned to the pool. Enabling this value can reduce the chance of the requested number of nodes to be allocated in the pool. If not specified, this value defaults to 'Disabled'.	'Disabled' 'Enabled'
maxTasksPerNode	The maximum number of tasks that can run concurrently on a single compute node in the pool.	int
metadata	The Batch service does not assign any meaning to metadata; it is solely for the use of user code.	MetadataItem[]
networkConfiguration	The network configuration for a pool.	NetworkConfiguration
scaleSettings	Defines the desired size of the pool. This can either be 'fixedScale' where the requested targetDedicatedNodes is specified, or 'autoScale' which defines a formula which is periodically reevaluated. If this property is not specified, the pool will have a fixed scale with 0 targetDedicatedNodes.	ScaleSettings
startTask	In an PATCH (update) operation, this property can be set to an empty object to remove the start task from the pool.	StartTask
taskSchedulingPolicy	Specifies how tasks should be distributed across compute nodes.	TaskSchedulingPolicy
userAccounts	The list of user accounts to be created on each node in the pool.	UserAccount[]
vmSize	For information about available sizes of virtual machines for Cloud Services pools (pools created with cloudServiceConfiguration), see Sizes for Cloud Services (https://azure.microsoft.com/documentation/articles/cloud-services-sizes-specs/). Batch supports all Cloud Services VM sizes except ExtraSmall. For information about available VM sizes for pools using images from the Virtual Machines Marketplace (pools created with virtualMachineConfiguration) see Sizes for Virtual Machines (Linux) (https://azure.microsoft.com/documentation/articles/virtual-machines-linux-sizes/) or Sizes for Virtual Machines (Windows) (https://azure.microsoft.com/documentation/articles/virtual-machines-windows-sizes/). Batch supports all Azure VM sizes except STANDARD_A0 and those with premium storage (STANDARD_GS, STANDARD_DS, and STANDARD_DSV2 series).	string

ResourceFile

Name	Description	Value
blobSource	This URL must be readable using anonymous access; that is, the Batch service does not present any credentials when downloading the blob. There are two ways to get such a URL for a blob in Azure storage: include a Shared Access Signature (SAS) granting read permissions on the blob, or set the ACL for the blob or its container to allow public access.	string (required)
fileMode	This property applies only to files being downloaded to Linux compute nodes. It will be ignored if it is specified for a resourceFile which will be downloaded to a Windows node. If this property is not specified for a Linux node, then a default value of 0770 is applied to the file.	string
filePath	The location on the compute node to which to download the file, relative to the task's working directory.	string (required)

ScaleSettings

Name	Description	Value

fixedScale	This property and autoScale are mutually exclusive and one of the properties must be specified.	FixedScaleSettings

StartTask

Name	Description	Value
commandLine	The command line does not run under a shell, and therefore cannot take advantage of shell features such as environment variable expansion. If you want to take advantage of such features, you should invoke the shell in the command line, for example using "cmd /c MyCommand" in Windows or "/bin/sh -c MyCommand" in Linux. Required if any other properties of the startTask are specified.	string
environmentSettings	A list of environment variable settings for the start task.	EnvironmentSetting[]
maxTaskRetryCount	The Batch service retries a task if its exit code is nonzero. Note that this value specifically controls the number of retries. The Batch service will try the task once, and may then retry up to this limit. For example, if the maximum retry count is 3, Batch tries the task up to 4 times (one initial try and 3 retries). If the maximum retry count is 0, the Batch service does not retry the task. If the maximum retry count is -1, the Batch service retries the task without limit.	int
resourceFiles	A list of files that the Batch service will download to the compute node before running the command line.	ResourceFile[]
userIdentity	If omitted, the task runs as a non-administrative user unique to the task.	UserIdentity
waitForSuccess	If true and the start task fails on a compute node, the Batch service retries the start task up to its maximum retry count (maxTaskRetryCount). If the task has still not completed successfully after all retries, then the Batch service marks the compute node unusable, and will not schedule tasks to it. This condition can be detected via the node state and scheduling error detail. If false, the Batch service will not wait for the start task to complete. In this case, other tasks can start executing on the compute node while the start task is still running; and even if the start task fails, new tasks will continue to be scheduled on the node. The default is false.	bool

NetworkConfiguration

Name	Description	Value
endpointConfiguration	Pool endpoint configuration is only supported on pools with the virtualMachineConfiguration property.	PoolEndpointConfiguration
subnetId	The virtual network must be in the same region and subscription as the Azure Batch account. The specified subnet should have enough free IP addresses to accommodate the number of nodes in the pool. If the subnet doesn't have enough free IP addresses, the pool will partially allocate compute nodes, and a resize error will occur. The 'MicrosoftAzureBatch' service principal must have the 'Classic Virtual Machine Contributor' Role-Based Access Control (RBAC) role for the specified VNet. The specified subnet must allow communication from the Azure Batch service to be able to schedule tasks on the compute nodes. This can be verified by checking if the specified VNet has any associated Network Security Groups (NSG). If communication to the compute nodes in the specified subnet is denied by an NSG, then the Batch service will set the state of the compute nodes to unusable. For pools created via virtualMachineConfiguration the Batch account must have poolAllocationMode userSubscription in order to use a VNet. If the specified VNet has any associated Network Security Groups (NSG), then a few reserved system ports must be enabled for inbound communication. For pools created with a virtual machine configuration, enable ports 29876 and 29877, as well as port 22 for Linux and port 3389 for Windows. For pools created with a cloud service configuration, enable ports 10100, 20100, and 30100. Also enable outbound connections to Azure Storage on port 443. For more details see: /azure/batch/batch-api-basics#virtual-network-vnet-and-firewall-configuration	string

access	The action that should be taken for a specified IP address, subnet range or tag.	'Allow' 'Deny' (required)
priority	Priorities within a pool must be unique and are evaluated in order of priority. The lower the number the higher the priority. For example, rules could be specified with order numbers of 150, 250, and 350. The rule with the order number of 150 takes precedence over the rule that has an order of 250. Allowed priorities are 150 to 3500. If any reserved or duplicate values are provided the request fails with HTTP status code 400.	int (required)
sourceAddressPrefix	Valid values are a single IP address (i.e. 10.10.10.10), IP subnet (i.e. 192.168.1.0/24), default tag, or * (for all addresses). If any other values are provided the request fails with HTTP status code 400.	string (required)

certificates	For Windows compute 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.	CertificateReference[]
deploymentConfiguration	Using CloudServiceConfiguration specifies that the nodes should be creating using Azure Cloud Services (PaaS), while VirtualMachineConfiguration uses Azure Virtual Machines (IaaS).	DeploymentConfiguration
displayName	The display name need not be unique and can contain any Unicode characters up to a maximum length of 1024.	string

maxTasksPerNode	The maximum number of tasks that can run concurrently on a single compute node in the pool.	int
metadata	The Batch service does not assign any meaning to metadata; it is solely for the use of user code.	MetadataItem[]
networkConfiguration	The network configuration for a pool.	NetworkConfiguration
scaleSettings	Defines the desired size of the pool. This can either be 'fixedScale' where the requested targetDedicatedNodes is specified, or 'autoScale' which defines a formula which is periodically reevaluated.

For information about available VM sizes for pools using images from the Virtual Machines Marketplace (pools created with virtualMachineConfiguration) see Sizes for Virtual Machines (Linux) (https://azure.microsoft.com/documentation/articles/virtual-machines-linux-sizes/) or Sizes for Virtual Machines (Windows) (https://azure.microsoft.com/documentation/articles/virtual-machines-windows-sizes/). Batch supports all Azure VM sizes except STANDARD_A0 and those with premium storage (STANDARD_GS, STANDARD_DS, and STANDARD_DSV2 series).	string

ResourceFile

Name	Description	Value
blobSource	This URL must be readable using anonymous access; that is, the Batch service does not present any credentials when downloading the blob. There are two ways to get such a URL for a blob in Azure storage: include a Shared Access Signature (SAS) granting read permissions on the blob, or set the ACL for the blob or its container to allow public access.	string (required)
fileMode	This property applies only to files being downloaded to Linux compute nodes. It will be ignored if it is specified for a resourceFile which will be downloaded to a Windows node. If this property is not specified for a Linux node, then a default value of 0770 is applied to the file.	string

fixedScale	This property and autoScale are mutually exclusive and one of the properties must be specified.	FixedScaleSettings

StartTask

Name	Description	Value
commandLine	The command line does not run under a shell, and therefore cannot take advantage of shell features such as environment variable expansion. If you want to take advantage of such features, you should invoke the shell in the command line, for example using "cmd /c MyCommand" in Windows or "/bin/sh -c MyCommand" in Linux. Required if any other properties of the startTask are specified.	string
environmentSettings	A list of environment variable settings for the start task.	EnvironmentSetting[]
maxTaskRetryCount	The Batch service retries a task if its exit code is nonzero. Note that this value specifically controls the number of retries. The Batch service will try the task once, and may then retry up to this limit. For example, if the maximum retry count is 3, Batch tries the task up to 4 times (one initial try and 3 retries). If the maximum retry count is 0, the Batch service does not retry the task. If the maximum retry count is -1, the Batch service retries the task without limit.	int
resourceFiles	A list of files that the Batch service will download to the compute node before running the command line.	ResourceFile[]
userIdentity	If omitted, the task runs as a non-administrative user unique to the task.	UserIdentity
waitForSuccess	If true and the start task fails on a compute node, the Batch service retries the start task up to its maximum retry count (maxTaskRetryCount). If the task has still not completed successfully after all retries, then the Batch service marks the compute node unusable, and will not schedule tasks to it. This condition can be detected via the node state and scheduling error detail. If false, the Batch service will not wait for the start task to complete. In this case, other tasks can start executing on the compute node while the start task is still running; and even if the start task fails, new tasks will continue to be scheduled on the node. The default is false.	bool
