Verwenden Sie docker ps
diese Option , um die Container-ID abzurufen.
Dann docker inspect -f '{{ .Mounts }}' containerid
Beispiel:
Schalter 1
$ docker run -it -v /tmp:/tmp ubuntu:14.04 /bin/bash
Terminal 2
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ddb7b55902cc ubuntu:14.04 "/bin/bash" About a minute ago Up About a minute distracted_banach
$ docker inspect -f "{{ .Mounts }}" ddb7
map[/tmp:/tmp]
Die Ausgabe
map[/tmp:/tmp]
ist anscheinend auf die Verwendung der Go- Sprache zur Implementierung der Docker-Befehlstools zurückzuführen.
Der docker inspect
Befehl ohne das -f format
ist ziemlich ausführlich. Da es sich um JSON handelt, können Sie es an Python oder NodeJS weiterleiten und alles extrahieren, was Sie benötigen.

docker history <image name>
zeigt die in ein Bild eingebrannten Ebenen. Leider docker history
scheint es durch die Formatierung und das Fehlen von Optionen zur Auswahl der angezeigten Elemente beeinträchtigt zu werden.
Über das Flag --no-trunc können Sie knappe und ausführliche Formate auswählen.
