gcloud alpha run services update-traffic

NAME: gcloud alpha run services update-traffic - adjust the traffic assignments for a Cloud Run service
SYNOPSIS: gcloud alpha run services update-traffic [[SERVICE] --namespace=NAMESPACE] [--async] [--breakglass=JUSTIFICATION] [--region=REGION] [--clear-tags | --set-tags=[TAG=REVISION,…] | --remove-tags=[TAG,…] --update-tags=[TAG=REVISION,…]] [--to-latest | --to-revisions=[REVISION-NAME=PERCENTAGE,…] | --to-tags=[TAG=PERCENTAGE,…]] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: (ALPHA) Adjust the traffic assignments for a Cloud Run service.
EXAMPLES: To assign 10% of traffic to revision myservice-s5sxn and 90% of traffic to revision myservice-cp9kw run:
gcloud alpha run services update-traffic myservice --to-revisions=myservice-s5sxn=10,myservice-cp9kw=90

To increase the traffic to revision myservice-s5sxn to 20% and by reducing the traffic to revision myservice-cp9kw to 80% run:
gcloud alpha run services update-traffic myservice --to-revisions=myservice-s5sxn=20

To rollback to revision myservice-cp9kw run:
gcloud alpha run services update-traffic myservice --to-revisions=myservice-cp9kw=100

To assign 100% of traffic to the current or future LATEST revision run:
gcloud alpha run services update-traffic myservice --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 traffic to always float to the latest revision:
gcloud alpha run services update-traffic myservice --to-revisions=LATEST=10
POSITIONAL ARGUMENTS: Service resource - Service to update the configuration of. The arguments in this group can be used to specify the attributes of this resource.

[SERVICE]

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

provide the argument SERVICE on the command line;

specify the service name from an interactive prompt.

--namespace=NAMESPACE

Specific to Cloud Run for Anthos: Kubernetes namespace for the service.
To set the namespace attribute:

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

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

provide the argument --namespace on the command line;

set the property run/namespace;

For Cloud Run on Kubernetes Engine, defaults to "default". Otherwise, defaults to project ID.;

provide the argument project on the command line;

set the property core/project.
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].

Specify traffic tags. Traffic tags can be assigned to a revision by name or to the latest ready revision. Assigning a tag to a revision generates a URL prefixed with the tag that allows addressing that revision directly, regardless of the percent traffic specified. Keys are tags. Values are revision names or "LATEST" for the latest ready revision. For example, --set-tags=candidate=LATEST,current=myservice-v1 assigns the tag "candidate" to the latest ready revision and the tag "current" to the revision with name "myservice-v1" and clears any existing tags. Changing tags does not affect the traffic percentage assigned to revisions. When using a tags flag and one or more of --to-latest and --to-revisions in the same command, the tags change occurs first then the traffic percentage change occurs.
At most one of these can be specified:

--clear-tags

Remove all tags.

--set-tags=[TAG=REVISION,…]

List of key-value pairs to set as tags. All existing tags will be removed first.

Only --update-tags and --remove-tags can be used together. If both are specified, --remove-tags will be applied first.

--remove-tags=[TAG,…]

List of tags to be removed.

--update-tags=[TAG=REVISION,…]

List of key-value pairs to set as tags.

At most one of these can be specified:

--to-latest

True to assign 100 percent of traffic to the 'latest' revision of this service. Note that when a new revision is created, it will become the 'latest' and traffic will be directed to it. Defaults to False. Synonymous with '--to-revisions=LATEST=100'.

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

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

--to-tags=[TAG=PERCENTAGE,…]

Comma separated list of traffic assignments in the form TAG=PERCENTAGE. TAG must match a traffic tag on a revision of the service. It may match a previously-set tag, or one assigned using the --set-tags or --update-tags flags on this command. PERCENTAGE must be an integer percentage between 0 and 100 inclusive. Up to 100 percent of traffic may be assigned. If 100 percent of traffic is assigned, the service traffic is updated as specified. If under 100 percent of traffic is assigned, the service traffic is updated as specified to the given tags, and other traffic is scaled up or down proportionally. For example, assume the revision tagged next is serving 40 percent of traffic and the revision tagged current is serving 60 percent. If next is assigned 45 percent of traffic and no assignment is made for current, the service is updated with next assigned 45 percent of traffic and current scaled down to 55 percent.

Run $ gcloud help for details.
NOTES: This command is currently in alpha and might change without notice. If this command fails with API permission errors despite specifying the correct project, you might be trying to access an API with an invitation-only early access allowlist. These variants are also available:
