endpointConfiguration Pool endpoint configuration is only supported on pools with the virtualMachineConfiguration property. PoolEndpointConfiguration
publicIPAddressConfiguration This property is only supported on Pools with the virtualMachineConfiguration property. PublicIPAddressConfiguration
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. 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 cloudServiceConfiguration pools, only 'classic' VNETs are supported. 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 4096. 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)
sourcePortRanges Valid values are '*' (for all ports 0 - 65535) or arrays of ports or port ranges (i.e. 100-200). The ports should in the range of 0 to 65535 and the port ranges or ports can't overlap. If any other values are provided the request fails with HTTP status code 400. Default value will be *. string[]

PoolEndpointConfiguration

Name Description Value
inboundNatPools The maximum number of inbound NAT pools per Batch pool is 5. If the maximum number of inbound NAT pools is exceeded the request fails with HTTP status code 400. This cannot be specified if the IPAddressProvisioningType is NoPublicIPAddresses. InboundNatPool[] (required)

PoolProperties

Name Description Value
applicationLicenses 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. string[]
applicationPackages Changes to application package references 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. There is a maximum of 10 application package references on any given pool. 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'

ResourceFile

Name Description Value
autoStorageContainerName The autoStorageContainerName, storageContainerUrl and httpUrl properties are mutually exclusive and one of them must be specified. string
blobPrefix The property is valid only when autoStorageContainerName or storageContainerUrl is used. This prefix can be a partial filename or a subdirectory. If a prefix is not specified, all the files in the container will be downloaded. string
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 If the httpUrl property is specified, the filePath is required and describes the path which the file will be downloaded to, including the filename. Otherwise, if the autoStorageContainerName or storageContainerUrl property is specified, filePath is optional and is the directory to download the files to. In the case where filePath is used as a directory, any directory structure already associated with the input data will be retained in full and appended to the specified filePath directory. The specified relative path cannot break out of the task's working directory (for example by using '..'). string
httpUrl The autoStorageContainerName, storageContainerUrl and httpUrl properties are mutually exclusive and one of them must be specified. If the URL points to Azure Blob Storage, it must be readable from compute nodes. There are three ways to get such a URL for a blob in Azure storage: include a Shared Access Signature (SAS) granting read permissions on the blob, use a managed identity with read permission, or set the ACL for the blob or its container to allow public access. string
identityReference The reference to a user assigned identity associated with the Batch pool which a compute node will use. ComputeNodeIdentityReference
storageContainerUrl The autoStorageContainerName, storageContainerUrl and httpUrl properties are mutually exclusive and one of them must be specified. This URL must be readable and listable from compute nodes. There are three ways to get such a URL for a container in Azure storage: include a Shared Access Signature (SAS) granting read and list permissions on the container, use a managed identity with read and list permissions, or set the ACL for the container to allow public access. string

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
containerSettings When this is specified, all directories recursively below the AZ_BATCH_NODE_ROOT_DIR (the root of Azure Batch directories on the node) are mapped into the container, all task environment variables are mapped into the container, and the task command line is executed in the container. TaskContainerSettings
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, however this is not recommended for a start task or any task. The default value is 0 (no retries). 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 true. bool

TaskContainerSettings

Name Description Value
containerRunOptions These additional options are supplied as arguments to the "docker create" command, in addition to those controlled by the Batch Service. string

publicIPAddressConfiguration This property is only supported on Pools with the virtualMachineConfiguration property. PublicIPAddressConfiguration
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. 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 cloudServiceConfiguration pools, only 'classic' VNETs are supported. For more details see: /azure/batch/batch-api-basics#virtual-network-vnet-and-firewall-configuration string

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 If the httpUrl property is specified, the filePath is required and describes the path which the file will be downloaded to, including the filename. Otherwise, if the autoStorageContainerName or storageContainerUrl property is specified, filePath is optional and is the directory to download the files to. In the case where filePath is used as a directory, any directory structure already associated with the input data will be retained in full and appended to the specified filePath directory. The specified relative path cannot break out of the task's working directory (for example by using '..'). string
httpUrl The autoStorageContainerName, storageContainerUrl and httpUrl properties are mutually exclusive and one of them must be specified. If the URL points to Azure Blob Storage, it must be readable from compute nodes. There are three ways to get such a URL for a blob in Azure storage: include a Shared Access Signature (SAS) granting read permissions on the blob, use a managed identity with read permission, or set the ACL for the blob or its container to allow public access. string
identityReference The reference to a user assigned identity associated with the Batch pool which a compute node will use. ComputeNodeIdentityReference
storageContainerUrl The autoStorageContainerName, storageContainerUrl and httpUrl properties are mutually exclusive and one of them must be specified. This URL must be readable and listable from compute nodes. There are three ways to get such a URL for a container in Azure storage: include a Shared Access Signature (SAS) granting read and list permissions on the container, use a managed identity with read and list permissions, or set the ACL for the container to allow public access. string

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
containerSettings When this is specified, all directories recursively below the AZ_BATCH_NODE_ROOT_DIR (the root of Azure Batch directories on the node) are mapped into the container, all task environment variables are mapped into the container, and the task command line is executed in the container. TaskContainerSettings
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, however this is not recommended for a start task or any task. The default value is 0 (no retries). 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 true. bool

TaskContainerSettings

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. 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 cloudServiceConfiguration pools, only 'classic' VNETs are supported. For more details see: /azure/batch/batch-api-basics#virtual-network-vnet-and-firewall-configuration string

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 If the httpUrl property is specified, the filePath is required and describes the path which the file will be downloaded to, including the filename. Otherwise, if the autoStorageContainerName or storageContainerUrl property is specified, filePath is optional and is the directory to download the files to. In the case where filePath is used as a directory, any directory structure already associated with the input data will be retained in full and appended to the specified filePath directory. The specified relative path cannot break out of the task's working directory (for example by using '..'). string
httpUrl The autoStorageContainerName, storageContainerUrl and httpUrl properties are mutually exclusive and one of them must be specified. If the URL points to Azure Blob Storage, it must be readable from compute nodes. There are three ways to get such a URL for a blob in Azure storage: include a Shared Access Signature (SAS) granting read permissions on the blob, use a managed identity with read permission, or set the ACL for the blob or its container to allow public access. string
identityReference The reference to a user assigned identity associated with the Batch pool which a compute node will use. ComputeNodeIdentityReference

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, however this is not recommended for a start task or any task. The default value is 0 (no retries). 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 true. bool
