Adjust update of log driver configuration

[markdumay]

The syno_docker_update.sh script updates the file /var/packages/Docker/etc/dockerd.json to fix an issue with Synology's db log driver. However, the script replaces the entire configuration file, instead of fixing the offending log driver only. This might introduce unwanted side effects.

Getting Error response from daemon: failed to initialize logging driver: failed to get logging factory: logger: no log driver named 'db' is registered: error looking up logging plugin db: plugin "db" not found after docker update and trying to start container

Can you share the full log of the syno_docker_update.sh command you ran? And what is the current content of your /var/packages/Docker/etc/dockerd.json file?

Both the script and daemon configuration appear to be fine. Can you try stopping and restarting the container(s)? It seems to refer to the now obsolete db log driver.

[merlin-zaraza]

yep, remove old container and add it again helps
thank you

[markdumay]

Great! I'll add an instruction to the README too ;-)

[exotsk]

Start container portainer failed: {"message":"failed to initialize logging driver: failed to get logging factory: logger: no log driver named 'db' is registered: error looking up logging plugin db: plugin "db" not found"}.

Any variants of /var/packages/Docker/etc/dockerd.json from Updated binaries are incompatible with btrfs #22 was not help.
Recreating containers have the same error, i cant run, pull any container and can`t delete images by GUI and by console

Current DSM version: 6.2.3
Current Docker version: 19.03.14
Current Docker Compose version: 1.27.4

restore is ok.
