Unable to find server files on the shared folder of Dsm7.2

[xpmod]

I mounted the container to a shared folder on Dsm7.2, but I couldn't find the server's corresponding files in the mounted shared folder. What should I do when creating a container to display the server files on the shared folder.
I didn't have this situation when using Docker in Dsm 7.1 before, but after updating to 7.2, Docker changed to Container Manager, which caused this situation.

Please provide more specifics.

[xpmod]

I chose to mount it to the doc/data folder, and after waiting for the server to open, I did not see any files about the server in the folder I mounted

You mounted the host path /doc

So you need to be looking in /doc which is an absolute path. In the file browser screenshot I can't tell what path that is exactly and there won't be a data subdirectory.
