POSITIONAL ARGUMENTS

NAME

Name of the forwarding rule to operate on.

FLAGS

--update-labels=[KEY=VALUE,...]

List of label KEY=VALUE pairs to update. If a label exists its value is modified, otherwise a new label is created.
Keys must start with a lowercase character and contain only hyphens (-), underscores (_), lowercase characters, and numbers. Values must contain only hyphens (-), underscores (_), lowercase characters, and numbers.

At most one of these may be specified:

--clear-labels

Remove all labels. If --update-labels is also specified then --clear-labels is applied first.
For example, to remove all labels:

$ gcloud beta compute forwarding-rules update --clear-labels

To set the labels to exactly "foo" and "baz":

$ gcloud beta compute forwarding-rules update --clear-labels \
  --update-labels foo=bar,baz=qux

--remove-labels=[KEY,...]

List of label keys to remove. If a label does not exist it is silently ignored.

At most one of these may be specified:

--global

If set, the forwarding rule is global.

--region=REGION

Region of the forwarding rule to operate on. If not specified, you may be prompted to select a region.
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.
