pathTemplateRewrite

If specified, the pattern rewrites the URL path (based on the :path header) using the HTTP template syntax. A corresponding path_template_match must be specified. Any template variables must exist in the path_template_match field. - -At least one variable must be specified in the path_template_match field - You can omit variables from the rewritten URL - The * and ** operators cannot be matched unless they have a corresponding variable name - e.g. {format=*} or {var=}. For example, a path_template_match of /static/{format=} could be rewritten as /static/content/{format} to prefix /content to the URL. Variables can also be re-ordered in a rewrite, so that /{country}/{format}/{suffix=**} can be rewritten as /content/{format}/{country}/{suffix}. At least one non-empty routeRules[].matchRules[].path_template_match is required. Only one of path_prefix_rewrite or path_template_rewrite may be specified.
