Ubuntu - Root Verzeichnis bei Docker ändern

[simp^ty]

Hallo Community,

ich brauche mal eure Hilfe. Ich versuche gerade nach der Neuinstallations meines Servers mit Ubuntu 20.04 das Root-Verzeichnis von Docker zu ändern.
Normal wird es ja unter /var/lib installiert, aber ich möchte es gerne alles unter /data/docker haben.

Dabei habe ich mich an diese und an diese Anleitung gehalten, den Order nach /data/docker verschoben, diese daemon.json mit dem neuen Pfad erstellt, die docker.service Datei geändert und den neuen Pfad mit -g hinzugefügt und Docker neugestartet.

Nur leider lässt sich Docker nicht mehr starten:

Ich weiß leider nicht, was das Problem hier ist.

Daher würde ich mich sehr freuen, wenn ihr mir weiterhelfen könnt

Was sagt journald?

journalctl -u docker.service

@BoeserBrot Ich habe den Output mal in einen Spoiler gepackt:

Bin zwar kein Docker-Experte, aber ich würde mal da ansetzen.
Die Option "-g" aus dem 2. Link (von 2021) scheint nicht mehr zu existieren.

Steht auch in den Kommentaren zu dem Artikel:

[BoeserBrot]

Fusion.Tio hat vermutlich den Fehler ausfindig gemacht. Ich würde die unit-Datei vom Docker-Service wieder in den Ausgangszustand versetzen und daemon.json so belassen.

 

[simp^ty]

Also, ich hab's jetzt so gemacht, ich habe das daemon.json wieder gelöscht und nur in das docker.service File das --data-root mit dem neuen Pfad geschrieben.
Der Docker Deamon läuft jetzt, obwohl ich die Meldung mit dem Flag --graph has been deprecated und the "graph" config file option is deprecated immer noch habe. Aber es läuft.
Danke euch!

 

[BoeserBrot]

Es is nicht ratsam die units in /lib/systemd/system zu editieren. Diese Dateien werden vom Paketmanager bereitgestellt und können bei Updates wieder überschrieben werden.

Mit der daemon.json kann dir das nicht passieren.

Solltest du dennoch die Service-Datei ändern wollen, dann empfiehlt sich folgendes Vorgehen:
