gcloud compute target-pools set-backup - set a backup pool for a target
|
|
pool
|
|
|
|
SYNOPSIS
|
|
gcloud compute target-pools set-backup NAME
|
|
(--backup-pool=BACKUP_POOL | --no-backup-pool)
|
|
[--failover-ratio=FAILOVER_RATIO] [--region=REGION]
|
|
[GCLOUD_WIDE_FLAG ...]
|
|
|
|
DESCRIPTION
|
|
gcloud 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 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 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.
