   -alertmanager.web.external-url string
     	The URL under which Alertmanager is externally reachable (eg. could be different than -http.alertmanager-http-prefix in case Alertmanager is served via a reverse proxy). This setting is used both to configure the internal requests router and to generate links in alert templates. If the external URL has a path portion, it will be used to prefix all HTTP endpoints served by Alertmanager, both the UI and API. (default http://localhost:8080/alertmanager)
