How to Automatically Share Docker Container Files with the Host System?
Asked by

I'm trying to figure out how to automatically pass files from a Docker container to my main filesystem using docker-compose. I'm running qbittorrent in a container that routes its traffic through NordVPN, allowing me to access my filesystem remotely with Tailscale. My goal is to have the data from qbittorrent available at a location on my bulk storage drive. Is there a way to specify this in the volumes section of the docker-compose.yaml?

When using Docker volumes, files are typically accessible on the host. If you define a volume by name, you can find it under `/var/docker/volumes`, though you might need root access to get in there. If you mount a specific folder with a direct path, you can access that folder directly. For example:
```yaml
services:
demo:
volumes:
- data:/var/some_folder
volumes:
data:
```
This will store the volume in `/var/lib/docker/volumes`. You can check with `docker volume ls` or `docker volume inspect volume_name` for more details. If you want to mount a specific folder, you can write:
```yaml
services:
demo:
volumes:
- ./data:/var/some_folder
```
This way, it's easier to organize things, and you can directly access it from the path specified in `docker-compose.yaml`.

DataDude89: Got it! Thanks for explaining. Just to clarify, if I set it up like this: ```yaml volumes: - /path/to/downloads:/media/blablabla ``` would I be able to see these files when I navigate to that location on my host system?
