ResourcePool

Represents the spec of a group of resources of the same type, for example machine type, disk, and accelerators, in a PersistentResource.

Fields

id string

Immutable. The unique id in a PersistentResource for referring to this resource pool. user can specify it if necessary. Otherwise, it's generated automatically.

machineSpec object (MachineSpec)

Required. Immutable. The specification of a single machine.

diskSpec object (DiskSpec)

Optional. Disk spec for the machine in this node pool.

usedReplicaCount string (int64 format)

Output only. The number of machines currently in use by training jobs for this resource pool. Will replace idle_replica_count.

autoscalingSpec object (AutoscalingSpec)

Optional. Optional spec to configure GKE or Ray-on-Vertex autoscaling

replicaCount string (int64 format)

Optional. The total number of machines to use for this resource pool.

JSON representation
{ "id": string, "machineSpec": { object (`MachineSpec`) }, "diskSpec": { object (`DiskSpec`) }, "usedReplicaCount": string, "autoscalingSpec": { object (`AutoscalingSpec`) }, "replicaCount": string }

AutoscalingSpec

The min/max number of replicas allowed if enabling autoscaling

Fields

minReplicaCount string (int64 format)

Optional. min replicas in the node pool, must be ≤ replicaCount and < maxReplicaCount or will throw error. For autoscaling enabled Ray-on-Vertex, we allow minReplicaCount of a resource_pool to be 0 to match the OSS Ray behavior(https://docs.ray.io/en/latest/cluster/vms/user-guides/configuring-autoscaling.html#cluster-config-parameters). As for Persistent Resource, the minReplicaCount must be > 0, we added a corresponding validation inside CreatePersistentResourceRequestValidator.java.

maxReplicaCount string (int64 format)

Optional. max replicas in the node pool, must be ≥ replicaCount and > minReplicaCount or will throw error

JSON representation
{ "minReplicaCount": string, "maxReplicaCount": string }

State

Describes the PersistentResource state.

Enums
`STATE_UNSPECIFIED`	Not set.
`PROVISIONING`	The PROVISIONING state indicates the persistent resources is being created.
`RUNNING`	The RUNNING state indicates the persistent resource is healthy and fully usable.
`STOPPING`	The STOPPING state indicates the persistent resource is being deleted.
`ERROR`	The ERROR state indicates the persistent resource may be unusable. Details can be found in the `error` field.
`REBOOTING`	The REBOOTING state indicates the persistent resource is being rebooted (PR is not available right now but is expected to be ready again later).
`UPDATING`	The UPDATING state indicates the persistent resource is being updated.

Required. If true, custom user-managed service account is enforced to run any workloads (for example, Vertex Jobs) on the resource. Otherwise, uses the Vertex AI Custom code service Agent.

serviceAccount string

Optional. Required when all below conditions are met * enableCustomServiceAccount is true; * any runtime is specified via ResourceRuntimeSpec on creation time, for example, Ray

The users must have iam.serviceAccounts.actAs permission on this service account and then the specified runtime containers will run as it.

This map needs to cover all the resource pool ids. Example: { "ray_head_node_pool": "head image" "ray_worker_node_pool1": "worker image" "ray_worker_node_pool2": "another worker image" }

headNodeResourcePoolId string

string

Output only. The resource name of NotebookRuntimeTemplate for the RoV Persistent Cluster The NotebokRuntimeTemplate is created in the same VPC (if set), and with the same Ray and Python version as the Persistent Cluster.
