Hvordan konverteres Lager driveren fra overlay til overlay2 i Container Station?

Container Station 3.0.8

Overview

Important

The original overlay storage driver has been deprecated and removed from Container Station since version 3.0. While Container Station on some systems might still support overlay in later versions, this support is temporary and will eventually be removed.

To ensure continued functionality and access to conversion assistance, please update to Container Station 3.0.8 or later. This update includes a storage driver check and will provide guidance on migrating to the recommended overlay2 driver if necessary.

Note

In case your Container Station utilizes a legacy storage driver, a prominent warning indicator will be displayed in the top banner alongside a pop-up reminder dialog for enhanced visibility.

Prerequisites

Ensure all containers and applications running within Container Station are stopped. This prevents any data corruption or unexpected behavior during the conversion process.
Create backups or exports of all your container-related data.
Remove existing images and containers after backing up or exporting container-related data.
For Docker Compose backups and in-depth data restoration procedures, consult the official Docker documentation on application rebuilding or contact the respective application developers for specific guidance. For details, see https://docs.docker.com.
During the conversion process of the storage driver from overlay to overlay2, the existing container data may need to be restructured or reconfigured, which could involve removing and re-importing containers. Backing up containers before conversion ensures that no data is lost, and restoring them afterward allows you to seamlessly transition to the new storage driver without compromising the operational state of the containers. For details, see How to back up and restore containers in Container Station.

Procedure

Open Container Station.
Locate the Legacy driver update required notification.
Note
The notification appears only for Container Stations using Docker Engine 24.0 (and later), near the application name in the title bar. This notification can serve as a reminder to proceed with the update.
Click Update Now.
The Overlay Storage Driver Update Required window appears.
Click Convert Driver.
The Legacy Storage Driver Conversion window appears.
Click Start.
The Prerequisites window appears.
Click the checkbox next to the statement confirming you have backups of your containers, images, and volumes.
Click Next.
Container Station starts the conversion process and updates the storage driver.
Click Finish.

Oversigt

Vigtigt

Den oprindelige overlay Lager driver er blevet udfaset og fjernet fra Container Station siden version 3.0. Mens Container Station på nogle systemer stadig kan understøtte overlay i senere versioner, er denne understøttelse midlertidig og vil til sidst blive fjernet.

For at sikre fortsat funktionalitet og adgang til konverteringshjælp, opdater venligst til Container Station 3.0.8 eller nyere. Denne opdatering inkluderer en Lager driverkontrol og vil give vejledning i at migrere til den anbefalede overlay2 driver, hvis nødvendigt.

Bemærk

Hvis din Container Station anvender en ældre Lager driver, vil en fremtrædende advarselsindikator blive vist i topbanneret sammen med en pop-up påmindelsesdialog for øget synlighed.

Forudsætninger

Sørg for, at alle containere og applikationer, der kører inden for Container Station, er stoppet. Dette forhindrer datakorruption eller uventet adfærd under konverteringsprocessen.
Opret sikkerhedskopier eller eksporter al din container-relaterede data.
Fjern eksisterende billeder og containere efter sikkerhedskopiering eller eksport af container-relaterede data.
For Docker Compose sikkerhedskopier og dybdegående datagendannelsesprocedurer, konsulter den officielle Docker dokumentation om applikationsgenopbygning eller kontakt de respektive applikationsudviklere for specifik vejledning. For detaljer, se https://docs.docker.com.
Under konverteringsprocessen af Lager driveren fra overlay til overlay2 kan det eksisterende containerdata have brug for at blive omstruktureret eller omkonfigureret, hvilket kan involvere fjernelse og genimport af containere. Sikkerhedskopiering af containere før konvertering sikrer, at ingen data går tabt, og gendannelse af dem efterfølgende giver dig mulighed for at overgå problemfrit til den nye Lager driver uden at kompromittere containerens operationelle tilstand. For detaljer, se Sådan sikkerhedskopieres og gendannes containere i Container Station.

Procedure

Åbn Container Station.
FindOpdatering af legacy-driver kræves notifikation.
Note
Notifikationen vises kun for Container Station, der bruger Docker Engine 24.0 (og senere), nær applikationsnavnet i titellinjen. Denne notifikation kan fungere som en påmindelse om at fortsætte med opdateringen.
Klik på Opdater nu.
Vinduet Overlay Lager Driver Update Required vises.
Klik på Konverter driver.
Vinduet Legacy Lager Driver Conversion vises.
Klik på Start.
Vinduet Forudsætninger vises.
Klik på afkrydsningsfeltet ved siden af erklæringen, der bekræfter, at du har sikkerhedskopier af dine containere, billeder og volumener.
Klik på Næste.
Container Station starter konverteringsprocessen og opdaterer Lager-driveren.
KlikAfslut.
