      Wir können aber auch das Dockerfile selbst exportieren.

      alfred@monitoring:~/GetInfo$ docker ps -all

      alfred@monitoring:~/GetInfo$ tar -tvf getinfo.tar

      Mit diesen Befehlen kann man überprüfen was alles im Container drinnenn ist (und das ist eine ganze Menge).

      Nun pushen wir den Container in das remote-Repository. Es werden natürlich alle Layer gepushed (in dem Falle gab es die darunterliegenden Layer noch nicht).

      alfred@monitoring:~/GetInfo$ docker push docker.registry:5000/getinfo:20211015

      The push refers to repository [docker.registry:5000/getinfo]

      alfred@monitoring:~/GetInfo$

      Kurze Kontrolle, ob der Container wirklich im Remote Repository gelandet ist.

      alfred@monitoring:~/GetInfo$ curl docker.registry:5000/v2/_catalog

      {"repositories":["getinfo","hello-world"]}

      alfred@monitoring:~/GetInfo$ curl docker.registry:5000/v2/getinfo/tags/list

       Abbildung 22: Longhorn Plattengröße

      Auch in der Longhorn-Anzeige kann man schön sehen, dass dieses Volume nicht mehr leer ist, und jetzt bereits ca. 1GB Platz braucht.

      Nun erzeugen wir ein yaml-File.
