Opsi Backup in Docker Container

[rene_z]

Hallo,
ich habe einen opsi über Docker eingerichet.
Ich wollte jetzt über einen Cronjob vom Host mit

Code: Alles auswählen

'docker exec opsi-server opsiconfd backup

' regelmäßige Updates erstellen, bekomme aber immer die gleichen Fehler. Wenn ich mit '

Code: Alles auswählen

docker exec -it opsi-server /bin/bash

' in den container gehe und dann 'opsiconfd backup' ausführe, funktioniert das problemlos.
Ich werde aus der Fehlermeldung leider nicht schlau. Kann mir da vielleicht einer Helfen?

Hier der Fehler:

Code: Alles auswählen

> docker exec -t opsi-server opsiconfd backup

Hallo,

beim Ausführen der bash im Container werden noch ein paar Umgebungsvariablen gesetzt.
So sollte es funktionieren:

Code: Alles auswählen

docker exec opsi-server bash -l -c "opsiconfd backup"
