Specifically, the name must be 1-63 characters long and match the regular expression `[a-z]([-a-z0-9]*[a-z0-9])?` which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.

`resource.selfLink`	`string` [Output Only] Server-defined URL for the resource.
`resource.hostRules[]`	`object` The list of HostRules to use against the URL.
`resource.hostRules[].description`	`string` An optional description of this resource. Provide this property when you create the resource.
`resource.hostRules[].hosts[]`	`string` The list of host patterns to match. They must be valid hostnames, except `` will match any string of `([a-z0-9-.])`. In that case, `*` must be the first character and must be followed in the pattern by either `-` or `.`.

`resource.pathMatchers[].description`	`string` An optional description of this resource. Provide this property when you create the resource.
`resource.pathMatchers[].defaultService`	`string` The full or partial URL to the BackendService resource. This will be used if none of the `pathRule`s or `routeRule`s defined by this PathMatcher are matched. For example, the following are all valid URLs to a BackendService resource: `https://www.googleapis.com/compute/v1/projects/project/global/backendServices/backendService` `compute/v1/projects/project/global/backendServices/backendService` `global/backendServices/backendService` If `defaultRouteAction` is additionally specified, advanced routing actions like URL Rewrites, etc. take effect prior to sending the request to the backend.
