CodePudding user response：

Connecting to 0.0.0.0 does not make any sense, as it is not the address of your device. The 0.0.0.0:9200->9200/tcp output from docker means that the service is listening on all interfaces (i.e., 0.0.0.0). Thus you can connect via 127.0.0.1 or your public IP address from your network card, for instance.
