ListWarmPools

prebuilds.list_warm_pools(PrebuildListWarmPoolsParams**kwargs) -> SyncWarmPoolsPage[WarmPool]
POST/gitpod.v1.PrebuildService/ListWarmPools

Lists warm pools with optional filtering.

Use this method to:

  • View all warm pools for a project
  • Monitor warm pool status across environment classes

Examples

  • List warm pools for a project:

    filter:
  projectIds: ["b0e12f6c-4c67-429d-a4a6-d9838b5da047"]
ParametersExpand Collapse
token: Optional[str]
page_size: Optional[int]
maximum100
minimum0
filter: Optional[Filter]

filter contains the filter options for listing warm pools

environment_class_ids: Optional[Sequence[str]]

environment_class_ids filters warm pools to specific environment classes

project_ids: Optional[Sequence[str]]

project_ids filters warm pools to specific projects

ReturnsExpand Collapse
class WarmPool: …

WarmPool maintains pre-created environment instances from a prebuild snapshot for near-instant environment startup. One warm pool exists per <project, environment_class> pair.

metadata: WarmPoolMetadata

metadata contains organizational and ownership information

created_at: datetime

created_at is when the warm pool was created

formatdate-time
updated_at: datetime

updated_at is when the warm pool was last updated

formatdate-time
environment_class_id: Optional[str]

environment_class_id is the environment class whose instances are warmed

formatuuid
organization_id: Optional[str]

organization_id is the ID of the organization that owns the warm pool

formatuuid
project_id: Optional[str]

project_id is the ID of the project this warm pool belongs to

formatuuid
runner_id: Optional[str]

runner_id is the runner that manages this warm pool. Derived from the environment class.

formatuuid
spec: WarmPoolSpec

spec contains the desired configuration for this warm pool

desired_phase: Optional[WarmPoolPhase]

desired_phase is the intended lifecycle phase for this warm pool. Managed by the API and reconciler.

One of the following:
"WARM_POOL_PHASE_UNSPECIFIED"
"WARM_POOL_PHASE_PENDING"
"WARM_POOL_PHASE_READY"
"WARM_POOL_PHASE_DEGRADED"
"WARM_POOL_PHASE_DELETING"
"WARM_POOL_PHASE_DELETED"
Deprecateddesired_size: Optional[int]

desired_size is the number of warm instances to maintain. Deprecated: Use min_size and max_size instead for dynamic scaling. Existing pools will be migrated to min_size=max_size=desired_size.

formatint32
maximum20
minimum1
max_size: Optional[int]

max_size is the maximum number of warm instances to maintain. The pool will never scale above this value. Must be >= min_size and <= 20.

formatint32
maximum20
minimum1
min_size: Optional[int]

min_size is the minimum number of warm instances to maintain. The pool will never scale below this value. Must be >= 0 and <= max_size. Set to 0 to allow full scale-down.

formatint32
maximum20
snapshot_id: Optional[str]

snapshot_id is the prebuild snapshot to warm up in the pool. Updated by the reconciler when a new prebuild completes for this project and environment class. Empty when no completed prebuild exists yet.

formatuuid
spec_version: Optional[str]

spec_version is incremented each time the spec is updated. Used for optimistic concurrency control.

status: WarmPoolStatus

status contains the current status reported by the runner

phase: WarmPoolPhase

phase is the current phase of the warm pool lifecycle

One of the following:
"WARM_POOL_PHASE_UNSPECIFIED"
"WARM_POOL_PHASE_PENDING"
"WARM_POOL_PHASE_READY"
"WARM_POOL_PHASE_DEGRADED"
"WARM_POOL_PHASE_DELETING"
"WARM_POOL_PHASE_DELETED"
desired_size: Optional[int]

desired_size is the current target number of instances the autoscaler has decided on. Unlike running_instances, this value is stable and does not fluctuate as instances are claimed and backfilled.

formatint32
failure_message: Optional[str]

failure_message contains details about why the warm pool is degraded or failed

running_instances: Optional[int]

running_instances is the number of running warm instances in the pool, ready to be claimed for near-instant environment startup.

formatint32
status_version: Optional[str]

status_version is incremented each time the status is updated. Used for optimistic concurrency control.

stopped_instances: Optional[int]

stopped_instances is the number of pre-provisioned but stopped instances in the pool. When a running instance is claimed, stopped instances are used to backfill the running pool faster than provisioning from scratch. Stopped instances only incur storage costs, allowing a larger total pool at lower cost than keeping all instances running.

formatint32
id: Optional[str]

id is the unique identifier for the warm pool

formatuuid
