gcloud compute url-maps add-host-rule - add a rule to a URL map to map hosts to a path matcher
gcloud compute url-maps add-host-rule NAME --hosts HOST,[HOST,...] --path-matcher-name PATH_MATCHER_NAME [--description DESCRIPTION] [GLOBAL-FLAG ...]
gcloud compute url-maps add-host-rule is used to add a mapping of hosts to a patch 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.
NAMEThe name of the URL map.
--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 patch matcher to use if a request matches this host rule. The patch matcher must already exist in the URL map (see gcloud compute url-maps add-path-matcher).
--description DESCRIPTIONAn optional, textual description for the host rule.
Run $ gcloud help for a description of flags available to all commands.
To create a host rule mapping the *-foo.google.com and google.com hosts to the www path matcher, run:
$ gcloud compute url-maps add-host-rule MY-URL-MAP \
--hosts *-foo.google.com google.com --path-matcher-name www
