I want to connect to port of container from browser on host with port 1344.
But Connection be fail when I accessed http://localhost:1344.
Why cannot connect to 1344 in spite of expose port?

And, http://localhost:8080 connection is correctly, But localhost:1344 has fail.

Why cannot connect to 1344?

docker-compose.yml:

services:
    datastore:
        image: busybox:latest
        volumes:
            - ./share:/share_to_container
