I’ve got docker-compose.yml which looks like that:

my-service:
...
volumes:
  - ./configuration/super.json:/configs/super.json

And dockerfile for this container which looks like that:

...
COPY configs/* /superdir/
...

The problem is: inside of the container /configs/super.json contains correct json, but looks like COPY is not working as i expect, because /superdir/super.json exists but is empty.

What’s intresting, when I stop this container, remove, again gonna do docker compose up -d my-service, the content of my json file will show up. What am i doing wrong?
