I have a nas (synology) and a mini pc(will install linux + docker) then I would like to use my nas drive as the storage (like storing photos) then use the docker on my linux machine and mount nas drive volume. But this should work when I manage on my linux machine.
It will be easier to manage on my nas then use my linux machine as a node/worker for running containers. So if you have any suggestions for this concept please let me know
I think you have a fundamental misunderstanding of what you are trying to achieve. And are over complicating things which is confusing everyone.
It would help greatly if you could give some indication of what containers you actually want to use.
From the sounds of it you want a file server which is your nas. Then you want to run an application in a docker container on your Linux machine.
Using Plex as an example, you would mount your Plex directories on your Linux server via NFS, then start the Plex container pointing at the mounted directory on the Linux server.
Nothing would run on your nas apart from the nfs file server.
The image you linked looks a bit more like a distributed worker. I use something similar where one server runs the core services and then I run specific workers on multiple other machines to distribute and increase the processing power. I don’t believe this is what you want to do as if it was, you would probably know it.
