5. Install Nextcloud

Filestash is in DockerHub : https://hub.docker.com/r/machines/filestash/tags
docker pull machines/filestash:latest
Maintained by mickaelkerjean

The Docker Compose file can be found here:
https://github.com/mickael-kerjean/filestash/blob/master/docker/docker-compose.yml

We have modified the docker composed file to use this local folder : /opt/filestash/storage

Run these commands :

sudo su -
mkdir /opt/nextcloud
cd /opt/nextcloud

nano docker-compose.yml

Put this in the file :
