gcloud beta compute url-maps add-host-rule

NAME
gcloud beta compute url-maps add-host-rule - add a rule to a URL map to map hosts to a path matcher
SYNOPSIS
gcloud beta compute url-maps add-host-rule URL_MAP --hosts=HOST,[HOST,…] --path-matcher-name=PATH_MATCHER_NAME [--description=DESCRIPTION] [--global     | --region=REGION] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
(BETA) gcloud beta compute url-maps add-host-rule is used to add a mapping of hosts to a path matcher in a URL map. The mapping will match the host component of HTTP requests to path matchers which in turn map the request to a backend service. Before adding a host rule, at least one path matcher must exist in the URL map to take care of the path component of the requests. gcloud compute url-maps add-path-matcher or gcloud compute url-maps edit can be used to add path matchers.
EXAMPLES
To create a host rule mapping the *-foo.example.com and example.com hosts to the www path matcher, run: 
gcloud beta compute url-maps add-host-rule MY-URL-MAP --hosts='*-foo.example.com,example.com' --path-matcher-name=www
POSITIONAL ARGUMENTS
URL_MAP
Name of the URL map to operate on.
REQUIRED FLAGS
--hosts=HOST,[HOST,…]
The set of hosts to match requests against. Each host must be a fully qualified domain name (FQDN) with the exception that the host can begin with a ``*´´ or ``*-´´. ``*´´ acts as a glob and will match any string of atoms to the left where an atom is separated by dots (``.´´) or dashes (``-´´).
--path-matcher-name=PATH_MATCHER_NAME
The name of the path matcher to use if a request matches this host rule. The path matcher must already exist in the URL map (see gcloud compute url-maps add-path-matcher).
OPTIONAL FLAGS
--description=DESCRIPTION
An optional, textual description for the host rule.
At most one of these can be specified:
--global
If set, the URL map is global.
--region=REGION
Region of the URL map to operate on. 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.
