Почему этот Tiny Go+Docker Server Crash SSH -соединение? ⇐ Linux

[Anonymous]

Следуя этому учебному пособию о том, как упаковать бинарную бинар в докер, при запуске Docker подключение SSH падает. Почему? package main

import (
"fmt"
"log"
"net/http"
)

func main() {
http.HandleFunc("/hello", HelloHandler)
fmt.Printf("Server running (port=8080), route: http://localhost:8080/hello\n")
if err := http.ListenAndServe(":8080", nil); err != nil {
log.Fatal(err)
}
}

func HelloHandler(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hello, World!")
}


dockerfile:

(Hang occured after a few seconds. And the HTTP server works well in those few seconds, or after and from local console instead of SSH.)
As expected, the docker stats doesn't show particular RAM consumption:
$ docker stats 06e2
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
