Resize the instance to a different flavor
Changes the instance's compute capacity to a different flavor (the Size tab's "Resize" button
in the instance detail page, which offers a picker of family/vCPU/RAM/price options and requires the
target to differ from the current flavor). The platform migrates the VM to the new size; vCPU,
RAM and pricing change while disks, IPs and configuration are preserved. Once complete, reads
return the updated embedded Flavor.
Validation: instance must exist and be visible → 404 NOT_FOUND; flavorId must reference an
existing flavor and must differ from the current one → 404 NOT_FOUND / 422 VALIDATION_FAILED;
current status must permit resize (ACTIVE or STOPPED, not BUILD/DELETING/already-RESIZE) and the
target flavor must have capacity in the instance's region — capacity shortfall → 409
CAPACITY_UNAVAILABLE (state conflicts surface on the same 409 status as CONFLICT).
Async & state: Asynchronous (202) returning an Operation. State path: ACTIVE|STOPPED →
RESIZE → VERIFY_RESIZE → terminal ACTIVE (confirmed) or ERROR (failed/reverted). The detail view
polls every 2.5s while status=RESIZE, and resource.updated SSE frames with kind=instance carry
the status/flavor patches.
Errors: 401 UNAUTHENTICATED; 403 FORBIDDEN; 404 NOT_FOUND for unknown instance or flavor;
409 CAPACITY_UNAVAILABLE when the target flavor lacks capacity (or the state forbids resize);
422 VALIDATION_FAILED for a missing/identical flavorId; 500 INTERNAL.
Idempotency/Concurrency: Idempotency-Key is optional (recommended); replay returns the
original Operation
rather than queueing a second migration. A resize while one is in flight returns 409. No If-Match
on the action route; concurrency is guarded by the state machine.
bearerTokenAuthorizationBearer <token>An API token (pc_live_…) or a service-account key (sak_live_…), created in Identity & Access Management and sent as Authorization: Bearer <token>. Requests are rate limited per credential and per tenant: every response carries X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset, and a refused request gets 429 RATE_LIMITED with Retry-After.
scopeId*stringOpaque ownership+authorization scope resolving to tenant + subscription + project.
instanceId*stringIdentifier of the compute instance.
Idempotency-Key?stringOptional; recommended for safe retries. When sent, the same key+body within 24h replays the original result and the same key with a different body is 409 CONFLICT; keys are unique per tenant. When an API token or service-account (bearer) caller omits it, the request is applied once with no replay protection (a retry may apply it again). A console session gets one from the edge.
uuidapplication/json- body
Target size for the resize action chosen in the Size tab picker.
flavorId*stringId of the target flavor; must differ from the instance's current flavor.
Resize accepted; returns the tracking Operation while the instance is in RESIZE state.
application/json- response
A long-running operation record. GET /operations/{operationId} returns its current state.
id*stringOperation identifier, unique platform-wide.
action*stringCanonical action id that started this operation, e.g. compute.instance.create.
state*OperationStateState machine for long-running operations. PENDING and RUNNING are transitional; the rest are terminal.
"PENDING""RUNNING""SUCCEEDED""FAILED""CANCELLED"resourceKind?|Kind of the target resource (matches RealtimeEvent.kind), null for resource-less actions.
resourceId?|Identifier of the target resource; null until the resource is allocated.
resourceName?|Human-readable name of the target resource captured when the operation was opened; null when unknown or the resource has been deleted (clients fall back to resourceId).
principalId?|Subject id (user id/email or service-account id) of the actor that initiated this operation, captured at the create chokepoint; null on internal/worker paths with no request-scoped principal or for historical rows. This is the real actor the Activity feed renders.
sourceIp?|Source IP address of the request that initiated this operation; null when unavailable (internal/worker paths, historical rows).
progressPercent?|Best-effort progress; null when the action does not report progress.
0 <= value <= 100error?|nullPopulated only when state is FAILED (or CANCELLED with partial rollback notes).
warning?|nullNon-fatal degradation recorded on an operation that still SUCCEEDED - the primary action completed but something explicitly requested could not be delivered (e.g. publicIp was requested at instance create but no floating IP could be assigned). On a CANCELLED create it reports that the provider resource had already been created and was kept (live and billed until deleted; details.disposition = left_in_place). Same code+message shape as error so clients render both uniformly; null when the operation ran without degradation.
startedAt?|When the worker began executing; null while PENDING.
finishedAt?|When a terminal state was reached; null while transitional.
