gcloud alpha compute url-maps add-host-rule

NAME
gcloud alpha compute url-maps add-host-rule - add a rule to a URL map to map hosts to a path matcher
SYNOPSIS
gcloud alpha 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
(ALPHA) gcloud alpha 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 alpha 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.

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:
