… and yes passing the password like this is security insanity, _plus_ you should also note that historically there have been some shell quoting issues which prevent certain password characters from being correctly communicated from the command line to the server. These can now be safely set in the configuration GUI, but you may find the command line switches useful while getting started.

@drwtsn32 If I may ask… You’ve been most helpful (thanks again), and it has been working flawlessly for two months now, but now there is an update for Duplicati, says the Duplicati GUI.
Are there default steps for Duplicati in Docker on Synology, to update Duplicati without breaking it?
Many Thanks.

If you set up the docker container properly (all important data is stored outside of the container), then it’s very easy! Go to the Registry and download the latest duplicati image:
The only complicating factor is if the “tag” is different from what you are currently running:
Once you get the notification that the download is complete, you can Stop the current container, then use the Clear command. This resets the container to the newest downloaded version. Then you just Start the container again.
It’s critical that you are storing your configuration information outside the container before doing this, otherwise you may lose important data! For the official duplicati docker image, you want to make sure `/data` is mapped to somewhere else on your NAS, as we discussed above.

@drwtsn32 Wow. That was way easier than expected. Again: many thanks. It worked. And I learned something new 👍

I was running this docker version of duplicati for a couple of months with no issues at all. I recently upgraded DSM to 7.0.1 and now duplicati is no longer working. When I browse to IP:8200, i get nothing. The container is running fine, apparently. There are no logs from the container, and when I go to a terminal for the container I just get a blank screen.
I’ve tried recreating the container, but exactly the same result.
Yes, my data for duplicati is stored outside the container.
Any ideas would be greatly appreciated.
Thanks

I’m running DSM 7.0.1-42218 over here, and do not experience the problem you’re describing.
Did you also update Docker itself in the Package Center? I’m running 20.10.3-1239.
Also, is the screen (browser window) really _completely_ blank? Or do see just the Duplicati menu, but all tasks seem to be gone? (I’ve had this happen to me a couple of times before, was unable to reproduce it though.)

I also upgraded from DSM 6.x to 7.0.1 recently. No issues with Docker for me though, it just continued to work. Can you confirm that it is still set to listen on port 8200? Click Details on your docker container and look here:

@BackupEverything @drwtsn32 Thanks for getting back to me.
The browser is not connecting on port 8200. Yes 8200 is set as the port in the container.
The container version:
This may not be a 7.0.1 issue, but might be a first reboot since installing issue…?
My duplicati config is in /data - did I screw up the config somehow? Does Duplicati not know how to find it?
Any other suggestions?
Thanks!

Your local port is actually 49156. Try going to `http://:49156` in your browser and see if the Duplicati UI shows up.
The 8200 in your screen shot is the port number from the container’s point of view. The local port is how you access it on your NAS, and it maps the traffic to the container at 8200. If you notice my screen shot I use 8200 for both. You can change this mapping if you stop Duplicati container and click the Edit button then go to the Port Settings tab.

If you want the docker files in “Shares/IT” on your NAS, then it’s ok. I leave my /data mapping set to “docker/duplicati” (I think that’s the default). But my preference is for each container to store its settings in the top level “docker” folder.
