GetWarmPool

POST/gitpod.v1.PrebuildService/GetWarmPool

Gets details about a specific warm pool.

Use this method to:

Check warm pool status and phase
View the current snapshot being warmed
Monitor pool health

Examples

Get warm pool:

warmPoolId: "a1b2c3d4-5678-9abc-def0-1234567890ab"

Body ParametersJSONExpand Collapse

warmPoolId: string

warm_pool_id specifies the warm pool to retrieve

formatuuid

ReturnsExpand Collapse

warmPool: WarmPool { metadata, spec, status, id }

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 { createdAt, updatedAt, environmentClassId, 3 more }

metadata contains organizational and ownership information

createdAt: string

created_at is when the warm pool was created

formatdate-time

updatedAt: string

updated_at is when the warm pool was last updated

formatdate-time

environmentClassId: optional string

environment_class_id is the environment class whose instances are warmed

formatuuid

organizationId: optional string

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

formatuuid

projectId: optional string

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

formatuuid

runnerId: optional string

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

formatuuid

spec: WarmPoolSpec { desiredPhase, desiredSize, maxSize, 3 more }

spec contains the desired configuration for this warm pool

desiredPhase: 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"

DeprecateddesiredSize: optional number

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

maxSize: optional number

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

minSize: optional number

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

snapshotId: optional string

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

specVersion: optional string

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

status: WarmPoolStatus { phase, desiredSize, failureMessage, 3 more }

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"

desiredSize: optional number

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

failureMessage: optional string

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

runningInstances: optional number

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

formatint32

statusVersion: optional string

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

stoppedInstances: optional number

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 string

id is the unique identifier for the warm pool

formatuuid
