POSITIONAL ARGUMENTS

NAME

Name of the managed instance group to operate on.

FLAGS

--autoscaling-file=PATH

Path of the file from which autoscaling configuration will be loaded. This flag allows you to atomically setup complex autoscalers.

--cool-down-period=COOL_DOWN_PERIOD

The time period that the autoscaler should wait before it starts collecting information from a new instance. This prevents the autoscaler from collecting information when the instance is initializing, during which the collected usage would not be reliable. The default is 60s. See $ gcloud topic datetimes for information on duration formats.

--custom-metric-utilization=[metric=METRIC],[utilization-target=UTILIZATION-TARGET],[utilization-target-type=UTILIZATION-TARGET-TYPE]

Adds a target metric value for the Autoscaler to use.

metric

Protocol-free URL of a Google Cloud Monitoring metric.

utilization-target

Value of the metric Autoscaler will aim to maintain (greater than 0.0).

utilization-target-type

How target is expressed. Valid values: DELTA_PER_MINUTE, DELTA_PER_SECOND, GAUGE.
Mutually exclusive with --update-stackdriver-metric.

--description=DESCRIPTION

Notes about Autoscaler.

--max-num-replicas=MAX_NUM_REPLICAS

Maximum number of replicas Autoscaler will set.

--min-num-replicas=MIN_NUM_REPLICAS

Minimum number of replicas Autoscaler will set.

--remove-stackdriver-metric=METRIC

Stackdriver metric to remove from autoscaling configuration. If the metric is the only input used for autoscaling the command will fail.

--scale-based-on-cpu

Autoscaler will be based on CPU utilization.

--scale-based-on-load-balancing

Use autoscaling based on load balancing utilization.

--stackdriver-metric-filter=FILTER

Expression for filtering samples used to autoscale, see cloud.google.com/monitoring/api/v3/filters

--stackdriver-metric-single-instance-assignment=ASSIGNMENT

Autoscaler will aim to maintain value of metric divided by number of instances at this level. Mutually exclusive with -stackdriver-metric-utilization-target-type, -stackdriver-metric-utilization-target-type, and --custom-metric-utilization.

--stackdriver-metric-utilization-target=TARGET

Value of the metric Autoscaler will aim to maintain. When specifying this flag you must also provide --stackdriver-metric-utilization-target-type. Mutually exclusive with --stackdriver-metric-single-instance-assignment and --custom-metric-utilization.

--stackdriver-metric-utilization-target-type=TARGET_TYPE

Value of the metric Autoscaler will aim to maintain. When specifying this flag you must also provide --stackdriver-metric-utilization-target. Mutually exclusive with --stackdriver-metric-single-instance-assignment and --custom-metric-utilization. TARGET_TYPE must be one of: delta-per-minute, delta-per-second, gauge.

--target-cpu-utilization=TARGET_CPU_UTILIZATION

Autoscaler will aim to maintain CPU utilization at target level (0.0 to 1.0).

--target-load-balancing-utilization=TARGET_LOAD_BALANCING_UTILIZATION

Autoscaler will aim to maintain the load balancing utilization level (greater than 0.0).

--update-stackdriver-metric=METRIC

Stackdriver metric to use as an input for autoscaling. When using this flag you must also specify target value of the metric by specifying --stackdriver-metric-single-instance-assignment or --stackdriver-metric-utilization-target and --stackdriver-metric-utilization-target-type. Mutually exclusive with --custom-metric-utilization.

At most one of these may be specified:

--region=REGION

Region of the managed instance group to operate on. If not specified, you may be prompted to select a region.
A list of regions can be fetched by running:

$ gcloud compute regions list

Overrides the default compute/region property value for this command invocation.

--zone=ZONE

Zone of the managed instance group to operate on. If not specified, you may be prompted to select a zone.
A list of zones can be fetched by running:

$ gcloud compute zones list

Overrides the default compute/zone property value for this command invocation.
