Volume outside container (docker)

Hi I’m using 10.0.8 installed with docker. I’m trying to save my data on a place outside of the container.
In the docker-compose.yml:

volumes:
  files:/mnt/data
  /data/VolumeOutsideContainer:/mnt/data

If I type :
volumes:
files: /data/VolumeOutsideContainer

It saves it on the struct /data/VolumeOutsideContainer inside the container.

This doesn’t work. In my mind this is all I should be needing to save the datafiles outsinde the container. Does somebody else have an input?

First I’d recommend you to read oficial documentation and tutorials about docker. Relevant info is in https://docs.docker.com/compose/compose-file/#volumes

I’m not sure if you should modify the docker-compose.yml file. I mean, that’s how ownCloud is intended to be deployed with docker. Unless you know what you’re doing, I wouldn’t change how things are deployed.
