-For Mac docker set `'api = "0.0.0.0:8080"'` instead of `'api = "127.0.0.1:8080"'`.
+By default, if the program runs in a docker, it will automatically replace `127.0.0.1` in the default configuration with `0.0.0.0` to ensure that the API interface is available.

 ```shell
 curl -H "Accept: application/json" http://127.0.0.1:55006/application/active
