Unfortunately, your docker code doesn't work. I entered "host" in Network and adjusted the volumes with those of my setting... Error message: Connection Lost
Log:
[ERROR] [/root/.cargo/registry/src/github.com-1ecc6299db9ec823/r2d2-0.8.10/src/lib.rs:121] Unable to open the database file
my code works for me, revise permission of your config folder when database is stored.
and yes my-net is my user-defined bridge network for all my dockers: https://docs.docker.com/network/drivers/bridge/
