Allowed values: target_tracking step scheduled

config

required

Kind-specific configuration. Unknown fields are refused.

target_tracking — metricName (wire form, e.g. stratum_compute_instance_cpu_percent; the dotted spelling is accepted), metricAggregation (Average | Sum | Maximum | Minimum, default Average), targetValue (> 0), estimatedInstanceWarmupSeconds (instances younger than this are excluded from the metric), disableScaleIn, optional query (full PromQL replacing the generated one; project-scoped either way). Desired = ceil(N × metric / target), clamped to [min, max].

step — metricName/metricAggregation/query as above, adjustmentType (ChangeInCapacity | ExactCapacity | PercentChangeInCapacity), steps[] of {lowerBound?, upperBound?, scalingAdjustment} on the absolute metric value (lower inclusive, upper exclusive, nil = open), optional cooldownSeconds (overrides the group’s), minAdjustmentMagnitude.

scheduled — scheduleCron (5-field), timeZone (IANA, default UTC), and at least one of minSize, maxSize, desiredSize. Fires once when due; a missed window fires once, never per missed occurrence.

issues

The findings of a rejected IAM policy document (custom and resource policies).

Array<object>

One finding of a rejected IAM policy document. A rejection lists every finding, so the author fixes the document in one round trip.

object

code

required

The finding, e.g. INVALID_DOCUMENT, UNKNOWN_ACTION, ACTION_NOT_APPLICABLE.

string

statement

required

Index of the statement at fault; -1 for the document as a whole.

integer

>= -1

detail

required

string

action

The offending action, where one is at fault (ACTION_NOT_APPLICABLE).

string

errors

Field errors, for codes that carry them: each problem at its field (see FieldError). Documented on the responses that set it, e.g. approveNodeJoin’s INVALID_INPUT and JOIN_APPROVAL_REFUSED. Absent otherwise.

Array<object>

One field’s problem, the stage-2 installer API’s shape. field is the field’s path, message what is wrong with it.

object

field

required

The field’s path, e.g. links[0].interface, disks[1].confirm, mgmt.address or role; empty for the whole request.

string

message

required

string

details

Structured facts about the refusal, for codes that carry them. The shape is fixed per code and documented on the response that answers it, e.g. IMAGE_POOL_MISMATCH (see ImagePoolMismatchDetails) and IMAGE_IN_USE. Absent for codes that carry none.
