Batch Create Instances

View as Markdown
Batch create multiple Instances for Tenant with NVLink domain-aware machine allocation. This endpoint creates multiple instances in a single atomic transaction. All instances share the same configuration (interfaces, OS, SSH keys, etc.) but are assigned different machines. When `topologyOptimized` is true (default), all instances must be allocated on machines within the same NVLink domain. If insufficient machines are available in a single NVLink domain, the request will fail. When `topologyOptimized` is false, instances can be spread across different NVLink domains. Instance names are automatically generated using the `namePrefix` with a random 6-character suffix (e.g., "worker" becomes "worker-abc123", "worker-def456"). Org must have a Tenant entity. User must have authorization role with `TENANT_ADMIN` suffix.

Authentication

AuthorizationBearer
``` export JWT_BEARER_TOKEN="<jwt-bearer-token>" # Example org name: "acme-inc export ORG_NAME=<org-name> # Use the JWT bearer token in your API request auth header: curl -v -X GET -H "Content-Type: application/json" -H "Authorization: Bearer $JWT_BEARER_TOKEN" https://nico-rest-api.nico.svc.cluster.local/v2/org/$ORG_NAME/nico/user/current ```

Path parameters

orgstringRequired
Name of the Org

Request

This endpoint expects an object.
namePrefixstringRequired2-240 characters

Prefix for instance names. Instances will be named with this prefix followed by a random 6-character suffix (e.g., “worker” becomes “worker-abc123”)

countintegerRequired2-18

Number of instances to create in this batch. Minimum 2, maximum 18 (limited by topology domain size)

tenantIdstringRequiredformat: "uuid"
ID of the Tenant creating the Instances
instanceTypeIdstringRequiredformat: "uuid"
ID of the Instance Type to use for all Instances in the batch
vpcIdstringRequiredformat: "uuid"
ID of the VPC the Instances should belong to
descriptionstring or nullOptional<=1024 characters
Description applied to all instances in the batch, optional
secondaryVpcIdslist of stringsOptional

IDs of additional VPCs the Instances should attach to through non-primary interfaces. This field may only be specified when every entry in interfaces uses vpcPrefixId. IDs must be unique, must be valid UUIDs, and must not include the primary vpcId.

userDatastring or nullOptional
User data applied to all instances. Can only be specified if allowOverride is set to true in Operating System
operatingSystemIdstring or nullOptionalformat: "uuid"
Must be specified if iPXE Script field is empty
networkSecurityGroupIdstring or nullOptionalformat: "uuid"
ID of a Network Security Group to attach to all instances
ipxeScriptstring or nullOptional
Override iPXE script specified in OS, must be specified if Operating System is not specified
alwaysBootWithCustomIpxebooleanOptional
When set to true, the iPXE script specified by OS or overridden here will always be run when rebooting the Instances. OS must be of iPXE type.
phoneHomeEnabledbooleanOptional
When set to true, the Instances will be enabled with the Phone Home service.
labelsmap from strings to stringsOptional

Key-value objects to be applied to all instances (shared across all instances)

interfaceslist of objectsOptional

Interface configuration shared across all instances. At least one interface must be specified unless autoNetwork is true. Either Subnet or VPC Prefix interfaces allowed, only one of the Subnets or VPC Prefixes can be attached over Physical interface. Interface ipAddress is not supported for batch instance creation requests. Mutually exclusive with autoNetwork: when autoNetwork is true this list MUST be empty.

autoNetworkbooleanOptional

When true, asks NICo to auto-resolve each Instance’s network interfaces from the host’s underlay (HostInband) network segments. Intended for instances on zero-DPU hosts (or hosts with their DPU in NIC mode). When true: (1) the target VPC’s networkVirtualizationType MUST be FLAT, (2) interfaces MUST be empty or omitted, and (3) secondaryVpcIds MUST be empty or omitted.

infinibandInterfaceslist of objectsOptional
InfiniBand interface configuration shared across all instances
dpuExtensionServiceDeploymentslist of objectsOptional
DPU Extension Services to deploy to all instances in the batch
nvLinkInterfaceslist of objectsOptional

NVLink interface configuration shared across all instances. A subset of GPUs may be specified. Each item references one GPU index (deviceInstance) and one NVLink Logical Partition. Different interfaces may reference different NVLink Logical Partitions.

sshKeyGroupIdslist of stringsOptional
SSH Key Group IDs that will provide Serial over LAN access to all instances
topologyOptimizedbooleanOptionalDefaults to true

When true (default), all instances must be allocated on machines within the same NVLink domain. When false, instances can be spread across different NVLink domains.
