How to keep power user preferences in Docker ResilioSync?

[xfelix]

I am using ResilioSync Docker on Synology NAS.

I find it not keep the changes of power user preferences settings. Everytime docker container restarts, the settings restore to default.

Some settings in preferences will keep, such as speed limit. But other settings like uncheck use upnp port mapping, check update, etc will return to default.

Any chance to save these settings to a config file or use docker variables to override the default settings?

Thanks.

I think i got the answer.

There's a sample sync.conf configuration which contains most advanced preferences, even can enforce https on the webgui.

Great.
