 - `-ui-content-path` ((#\_ui\_content\_path)) - This flag provides the option
   to change the path the Consul UI loads from and will be displayed in the browser.
   By default, the path is `/ui/`, for example `http://localhost:8500/ui/`. Only alphanumerics,
   `-`, and `_` are allowed in a custom path. `/v1/` is not allowed as it would overwrite
   the API endpoint.
