Update service auto scaling settings

Updates minimum and maximum memory limits per replica and idle mode scaling behavior for the service. Supports both vertical autoscaling (fixed replica count, variable memory) and horizontal autoscaling (variable replica count, fixed memory). The memory settings are available only for “production” services and must be a multiple of 4 starting from 8GB. For vertical autoscaling, please contact support to enable adjustment of numReplicas. For horizontal autoscaling (autoscalingMode “horizontal” with minReplicas/maxReplicas), contact support to enable the feature for your organization.

minReplicaMemoryGb

number

Minimum auto-scaling memory in Gb for a single replica. Available only for 'production' services. Must be a multiple of 4 and greater than or equal to 8. A range in vertical autoscaling; equal to maxReplicaMemoryGb in horizontal.

Intervalo obrigatório: 8 <= x <= 356Deve ser um múltiplo de 4

Exemplo:

16

maxReplicaMemoryGb

number

Maximum auto-scaling memory in Gb for a single replica. Available only for 'production' services. Must be a multiple of 4 and lower than or equal to 120 for non paid services or 356 for paid services. A range in vertical autoscaling; equal to minReplicaMemoryGb in horizontal.

Intervalo obrigatório: 8 <= x <= 356Deve ser um múltiplo de 4

Exemplo:

120

autoscalingMode

enum<string>

Target autoscaling mode. Omit to keep the service on its current mode. "vertical" runs a fixed replica count while memory scales between minReplicaMemoryGb and maxReplicaMemoryGb; "horizontal" scales the replica count between minReplicas and maxReplicas at a fixed per-replica memory (minReplicaMemoryGb equal to maxReplicaMemoryGb). Switching to horizontal requires the feature to be enabled for the organization.

Opções disponíveis:

vertical,

horizontal

Exemplo:

"vertical"

numReplicas

integer

Fixed replica count for vertical autoscaling (autoscalingMode "vertical"). Mutually exclusive with minReplicas/maxReplicas. When switching to vertical (autoscalingMode "vertical") with numReplicas and no memory, the service's stored baseline per-replica memory is kept as the new vertical range. Please contact support to enable adjustment of numReplicas.

Intervalo obrigatório: 1 <= x <= 20

Exemplo:

3

minReplicas

integer

Minimum number of replicas. A minReplicas/maxReplicas band scales the replica count in horizontal autoscaling (autoscalingMode "horizontal"). Must be provided together with maxReplicas. Mutually exclusive with numReplicas. Requires horizontal autoscaling to be enabled for the service, unless autoscalingMode is omitted or "vertical" and minReplicas equals maxReplicas (an equal band is then an accepted vertical fixed count and needs no horizontal entitlement).

Intervalo obrigatório: 1 <= x <= 20

Exemplo:

1

maxReplicas

integer

Maximum number of replicas. A minReplicas/maxReplicas band scales the replica count in horizontal autoscaling (autoscalingMode "horizontal"). Must be provided together with minReplicas. Mutually exclusive with numReplicas. Requires horizontal autoscaling to be enabled for the service, unless autoscalingMode is omitted or "vertical" and minReplicas equals maxReplicas (an equal band is then an accepted vertical fixed count and needs no horizontal entitlement).

Intervalo obrigatório: 1 <= x <= 20

Exemplo:

5

idleScaling

boolean

When set to true the service is allowed to scale down to zero when idle. True by default.

idleTimeoutMinutes

number

Set minimum idling timeout (in minutes). Must be >= 5 minutes.
