gcloud preview compute target-pools set-backup

NAME: gcloud preview compute target-pools set-backup - set a backup pool for a target pool
SYNOPSIS: gcloud preview compute target-pools set-backup NAME ( --backup-pool = BACKUP_POOL | --no-backup-pool ) [ --failover-ratio = FAILOVER_RATIO ] [ --region = REGION ] [ GCLOUD_WIDE_FLAG … ]
DESCRIPTION: (PREVIEW) gcloud preview compute target-pools set-backup is used to set a backup target pool for a primary target pool, which defines the fallback behavior of the primary pool. If the ratio of the healthy instances in the primary pool is at or below the specified --failover-ratio value , then traffic arriving at the load-balanced IP address will be directed to the backup pool.
EXAMPLES: To cause TARGET-POOL (in region us-central1 ) to fail over to BACKUP-POOL when more than half of the TARGET-POOL instances are unhealthy, run:
gcloud preview compute target-pools set-backup TARGET-POOL --backup-pool = BACKUP-POOL --failover-ratio = 0 .5 --region = us-central1

To remove BACKUP-POOL as a backup to TARGET-POOL , run:

gcloud preview compute target-pools set-backup TARGET-POOL --backup-pool = '' --region = us-central1
POSITIONAL ARGUMENTS: NAME

The name of the target pool for which to set the backup pool.
REQUIRED FLAGS: Exactly one of these must be specified:

--backup-pool = BACKUP_POOL

Name of the target pool that will serve as backup.

--no-backup-pool

Unsets the backup pool. This disables failover.
OPTIONAL FLAGS: --failover-ratio = FAILOVER_RATIO

The new failover ratio value for the target pool. This must be a float in the range of [0, 1].

--region = REGION

Region of the target pool to set a backup pool for. If not specified, you might be prompted to select a region (interactive mode only).
To avoid prompting when this flag is omitted, you can set the compute/region property:

gcloud config set compute/region REGION

A list of regions can be fetched by running:

gcloud compute regions list

To unset the property, run:

gcloud config unset compute/region

Alternatively, the region can be stored in the environment variable CLOUDSDK_COMPUTE_REGION .
GCLOUD WIDE FLAGS: These flags are available to all commands: --access-token-file , --account , --billing-project , --configuration , --flags-file , --flatten , --format , --help , --impersonate-service-account , --log-http , --project , --quiet , --trace-token , --user-output-enabled , --verbosity .
Run $ gcloud help for details.
