gcloud alpha run workers update-instance-split

NAME: gcloud alpha run workers update-instance-split - adjust the instance assignments for a Cloud Run worker
SYNOPSIS: gcloud alpha run workers update-instance-split [WORKER] [--async] [--breakglass=JUSTIFICATION] [--region=REGION] [--to-latest | --to-revisions=[REVISION-NAME=PERCENTAGE,…]] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: (ALPHA) Adjust the instance assignments for a Cloud Run worker.
EXAMPLES: To assign 10% of instances to revision my-worker-s5sxn and 90% of instances to revision my-worker-cp9kw run:
gcloud alpha run workers update-instance-split my-worker --to-revisions=my-worker-s5sxn=10,my-worker-cp9kw=90

To increase the instances to revision my-worker-s5sxn to 20% and by reducing the instances to revision my-worker-cp9kw to 80% run:
gcloud alpha run workers update-instance-split my-worker --to-revisions=my-worker-s5sxn=20

To rollback to revision my-worker-cp9kw run:
gcloud alpha run workers update-instance-split my-worker --to-revisions=my-worker-cp9kw=100

To assign 100% of instances to the current or future LATEST revision run:
gcloud alpha run workers update-instance-split my-worker --to-latest

You can also refer to the current or future LATEST revision in --to-revisions by the string "LATEST". For example, to set 10% of instances to always float to the latest revision:
gcloud alpha run workers update-instance-split my-worker --to-revisions=LATEST=10
POSITIONAL ARGUMENTS: Worker resource - Worker to update instance split of. This represents a Cloud resource. (NOTE) Some attributes are not given arguments in this group but can be set in other ways.
To set the project attribute:

provide the argument WORKER on the command line with a fully specified name;

specify the worker name from an interactive prompt with a fully specified name;

provide the argument --project on the command line;

set the property core/project.

[WORKER]

ID of the worker or fully qualified identifier for the worker.
To set the worker attribute:

provide the argument WORKER on the command line;

specify the worker name from an interactive prompt.
FLAGS: --async

Return immediately, without waiting for the operation in progress to complete.

--breakglass=JUSTIFICATION

Justification to bypass Binary Authorization policy constraints and allow the operation. See https://cloud.google.com/binary-authorization/docs/using-breakglass for more information. Next update or deploy command will automatically clear existing breakglass justification.

--region=REGION

Region in which the resource can be found. Alternatively, set the property [run/region].

At most one of these can be specified:

--to-latest

True to assign 100 percent of instances to the 'latest' revision of this service. Note that when a new revision is created, it will become the 'latest' and instances will be fully assigned to it unless configured otherwise using --[no-]promote flag. Defaults to False. Synonymous with '--to-revisions=LATEST=100'.

--to-revisions=[REVISION-NAME=PERCENTAGE,…]

Comma separated list of instance assignments in the form REVISION-NAME=PERCENTAGE. REVISION-NAME must be the name for a revision for the worker as returned by 'gcloud run workers revisions list --worker=WORKER' . PERCENTAGE must be an integer percentage between 0 and 100 inclusive. Ex worker-nw9hs=10,worker-nw9hs=20 Up to 100 percent of instances may be assigned. If the total of 100 percent of instances is assigned, the Worker instance split is updated as specified. If under 100 percent of instance split is assigned, the Worker instance split is updated as specified for revisions with assignments and instance split is scaled up or down proportionally as needed for revision that are currently serving workload but that do not have new assignments. For example assume revision-1 is serving 40 percent of workload and revision-2 is serving 60 percent. If revision-1 is assigned 45 percent of instances and no assignment is made for revision-2, the worker is updated with revsion-1 assigned 45 percent of instances and revision-2 scaled down to 55 percent. You can use "LATEST" as a special revision name to always put the given percentage of instance split on the latest ready revision.
