Request Body

Media Types: "application/json; odata=minimalmetadata"

Name	Type	Description
applicationPackageReferences	ApplicationPackageReference[]	A list of Packages to be installed on each Compute Node in the Pool. 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. If this element is present, it replaces any existing Package references. If you specify an empty collection, then all Package references are removed from the Pool. If omitted, any existing Package references are left unchanged.
certificateReferences	CertificateReference[]	A list of Certificates to be installed on each Compute Node in the Pool. If this element is present, it replaces any existing Certificate references configured on the Pool. If omitted, any existing Certificate references are left unchanged. 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.

The private key is used to automatically configure asymmetric-key based authentication for SSH between Compute Nodes in a Linux Pool when the Pool's enableInterNodeCommunication property is true (it is ignored if enableInterNodeCommunication is false). It does this by placing the key pair into the user's .ssh directory. If not specified, password-less SSH is not configured between Compute Nodes (no modification of the user's .ssh directory is done).

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 Compute Nodes in the Pool. If the subnet doesn't have enough free IP addresses, the Pool will partially allocate 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 Nodes. This can be verified by checking if the specified VNet has any associated Network Security Groups (NSG). If communication to the Nodes in the specified subnet is denied by an NSG, then the Batch service will set the state of the Compute Nodes to unusable. Only ARM virtual networks ('Microsoft.Network/virtualNetworks') are supported. If the specified VNet has any associated Network Security Groups (NSG), then a few reserved system ports must be enabled for inbound communication, including ports 29876 and 29877. Also enable outbound connections to Azure Storage on port 443. For more details see: https://docs.microsoft.com/azure/batch/nodes-and-pools#virtual-network-vnet-and-firewall-configuration

If both maxBatchInstancePercent and maxUnhealthyInstancePercent are assigned with value, the value of maxBatchInstancePercent should not be more than maxUnhealthyInstancePercent.
maxUnhealthyInstancePercent	integer	The maximum percentage of the total virtual machine instances in the scale set that can be simultaneously unhealthy, either as a result of being upgraded, or by being found in an unhealthy state by the virtual machine health checks before the rolling upgrade aborts. This constraint will be checked prior to starting any batch. The value of this field should be between 5 and 100, inclusive. If both maxBatchInstancePercent and maxUnhealthyInstancePercent are assigned with value, the value of maxBatchInstancePercent should not be more than maxUnhealthyInstancePercent.

StartTask

A Task which is run when a Node joins a Pool in the Azure Batch service, or when the Compute Node is rebooted or reimaged.

Name	Type	Description
commandLine	string	The command line of the StartTask. 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. If the command line refers to file paths, it should use a relative path (relative to the Task working directory), or use the Batch provided environment variable (https://docs.microsoft.com/azure/batch/batch-compute-node-environment-variables).
containerSettings	TaskContainerSettings	The settings for the container under which the StartTask runs. 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. Files produced in the container outside of AZ_BATCH_NODE_ROOT_DIR might not be reflected to the host disk, meaning that Batch file APIs will not be able to access those files.
environmentSettings	EnvironmentSetting[]	A list of environment variable settings for the StartTask.
maxTaskRetryCount	integer	The maximum number of times the Task may be retried. 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).
resourceFiles	ResourceFile[]	A list of files that the Batch service will download to the Compute Node before running the command line. There is a maximum size for the list of resource files. When the max size is exceeded, the request will fail and the response error code will be RequestEntityTooLarge. If this occurs, the collection of ResourceFiles must be reduced in size. This can be achieved using .zip files, Application Packages, or Docker Containers. Files listed under this element are located in the Task's working directory.
userIdentity	UserIdentity	The user identity under which the StartTask runs. If omitted, the Task runs as a non-administrative user unique to the Task.
waitForSuccess	boolean	Whether the Batch service should wait for the StartTask to complete successfully (that is, to exit with exit code 0) before scheduling any Tasks on the Compute Node. If true and the StartTask fails on a Node, the Batch service retries the StartTask up to its maximum retry count (maxTaskRetryCount). If the Task has still not completed successfully after all retries, then the Batch service marks the Node unusable, and will not schedule Tasks to it. This condition can be detected via the Compute Node state and failure info details. If false, the Batch service will not wait for the StartTask to complete. In this case, other Tasks can start executing on the Compute Node while the StartTask is still running; and even if the StartTask fails, new Tasks will continue to be scheduled on the Compute Node. The default is true.

containerRunOptions	string	Additional options to the container create command. These additional options are supplied as arguments to the "docker create" command, in addition to those controlled by the Batch Service.
imageName	string	The Image to use to create the container in which the Task will run. This is the full Image reference, as would be specified to "docker pull". If no tag is provided as part of the Image name, the tag ":latest" is used as a default.
