### If you only need to mount one file
### Do not mount single config file
You might not need to mount a folder of configs. You may just have one config file you want to use.
In that case you can just mount it directly. Mounting it as `default.ovpn` will let you omit `OPENVPN_CONFIG` as well.
Do not mount a single config directly. The container will fail if you try, since it causes sed errors when modify-openvpn-config.sh is executed.
Instead mount the directory where the config exists.
Compose sample:
```
- /volume1/docker/ipvanish/my-preferred-config-file.ovpn:/etc/openvpn/custom/default.ovpn
```bash
sed: cannot rename /etc/openvpn/custom/sedHeF3gS: Device or resource busy
```
