      Ein kurzer Test auf http://monitoring:8080/view/hello ergibt

       Abbildung 20: GetInfo Ausgabe

      Das heist das Programm funktioniert. Die Logausgabe sieht aus wie folgt:

      alfred@monitoring:~/GetInfo$ ./GetInfo

      2021/10/10 21:42:01 Main Started

      2021/10/10 21:42:16 hello.html

      ^C

      alfred@monitoring:~/GetInfo$

      Jetzt brauchen wir noch ein Docker-File

      alfred@monitoring:~/GetInfo$ cat dockerfile
