Cluster autoscaling
--enable-autoscaling-
Enables autoscaling for a node pool.
Enables autoscaling in the node pool specified by --node-pool or the default node pool if --node-pool is not provided. If not already, --max-nodes or --total-max-nodes must also be set.
--location-policy=LOCATION_POLICY-
Location policy specifies the algorithm used when scaling-up the node pool.
-
BALANCED- Is a best effort policy that aims to balance the sizes of available zones. -
ANY- Instructs the cluster autoscaler to prioritize utilization of unused reservations, and reduces preemption risk for Spot VMs.
LOCATION_POLICYmust be one of:BALANCED,ANY. -
--max-nodes=MAX_NODES-
Maximum number of nodes per zone in the node pool.
Maximum number of nodes per zone to which the node pool specified by --node-pool (or default node pool if unspecified) can scale. Ignored unless --enable-autoscaling is also specified.
--min-nodes=MIN_NODES-
Minimum number of nodes per zone in the node pool.
Minimum number of nodes per zone to which the node pool specified by --node-pool (or default node pool if unspecified) can scale. Ignored unless --enable-autoscaling is also specified.
--total-max-nodes=TOTAL_MAX_NODES-
Maximum number of all nodes in the node pool.
Maximum number of all nodes to which the node pool specified by --node-pool (or default node pool if unspecified) can scale. Ignored unless --enable-autoscaling is also specified.
--total-min-nodes=TOTAL_MIN_NODES-
Minimum number of all nodes in the node pool.
Minimum number of all nodes to which the node pool specified by --node-pool (or default node pool if unspecified) can scale. Ignored unless --enable-autoscaling is also specified.
-
Specifies minimum number of nodes to be created when best effort provisioning
enabled.
--enable-best-effort-provision- Enable best effort provision for nodes
--min-provision-nodes=MIN_PROVISION_NODES- Specifies the minimum number of nodes to be provisioned during creation
-
At most one of these can be specified:
--ephemeral-storage[=[local-ssd-count=LOCAL-SSD-COUNT]]-
Parameters for the ephemeral storage filesystem. If unspecified, ephemeral
storage is backed by the boot disk.
Examples:
gcloud beta container node-pools create node-pool-1 --cluster=example cluster --ephemeral-storage local-ssd-count=2'local-ssd-count' specifies the number of local SSDs to use to back ephemeral storage. Local SDDs use NVMe interfaces. For first- and second-generation machine types, a nonzero count field is required for local ssd to be configured. For third-generation machine types, the count field is optional because the count is inferred from the machine type.
See https://cloud.google.com/compute/docs/disks/local-ssd for more information.
--ephemeral-storage-local-ssd[=[count=COUNT]]-
Parameters for the ephemeral storage filesystem. If unspecified, ephemeral
storage is backed by the boot disk.
Examples:
gcloud beta container node-pools create node-pool-1 --cluster=example cluster --ephemeral-storage-local-ssd count=2'count' specifies the number of local SSDs to use to back ephemeral storage. Local SDDs use NVMe interfaces. For first- and second-generation machine types, a nonzero count field is required for local ssd to be configured. For third-generation machine types, the count field is optional because the count is inferred from the machine type.
See https://cloud.google.com/compute/docs/disks/local-ssd for more information.
--local-nvme-ssd-block[=[count=COUNT]]-
Adds the requested local SSDs on all nodes in default node pool(s) in the new
cluster.
Examples:
gcloud beta container node-pools create node-pool-1 --cluster=example cluster --local-nvme-ssd-block count=2'count' must be between 1-8 New nodes, including ones created by resize or recreate, will have these local SSDs.
For first- and second-generation machine types, a nonzero count field is required for local ssd to be configured. For third-generation machine types, the count field is optional because the count is inferred from the machine type.
See https://cloud.google.com/compute/docs/disks/local-ssd for more information.
--local-ssd-count=LOCAL_SSD_COUNT-
The number of local SSD disks to provision on each node, formatted and mounted
in the filesystem.
Local SSDs have a fixed 375 GB capacity per device. The number of disks that can be attached to an instance is limited by the maximum number of disks available on a machine, which differs by compute zone. See https://cloud.google.com/compute/docs/disks/local-ssd for more information.
-
At most one of these can be specified:
--location=LOCATION- Compute zone or region (e.g. us-central1-a or us-central1) for the cluster. Overrides the default compute/region or compute/zone value for this command invocation. Prefer using this flag over the --region or --zone flags.
--region=REGION- Compute region (e.g. us-central1) for a regional cluster. Overrides the default compute/region property value for this command invocation.
--zone=ZONE,-zZONE- Compute zone (e.g. us-central1-a) for a zonal cluster. Overrides the default compute/zone property value for this command invocation.
-
Specifies the reservation for the node pool.
--reservation=RESERVATION-
The name of the reservation, required when
--reservation-affinity=specific. --reservation-affinity=RESERVATION_AFFINITY-
The type of the reservation for the node pool.
RESERVATION_AFFINITYmust be one of:any,none,specific.
-
Options to specify the node identity.
-
Scopes options.
--scopes=[SCOPE,…]; default="gke-default"-
Specifies scopes for the node instances.
Examples:

Various scopes are automatically added based on feature usage. Such scopes are not added if an equivalent scope already exists.
-
monitoring-write: always added to ensure metrics can be written -
