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
{"name":"getinfo","tags":["20211015"]}

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.
