Remember, a few hours of trial and error can save you several minutes of looking at the README.
With that out of the way, this is how I store my container data, running on an application server, on my network attached storage device.
Below is based on my experimental Nextcloud setup at home1. I’m storing all data on my TrueNAS machine using NFSv4 as my local drive is quite small.
# docker-compose.yml version: '3.2' services: whatever: image: what/ever:latest volumes: - type: volume source: container-data target: /var/www/html/data volume: nocopy: true # [...] volumes: container-data: driver: local driver_opts: type: "nfs4" o: "addr=192.168.0.1,rw,nfsvers=4,async" device: ":/remote/path/to/data"
The relevant section of the volume documentation is here.
Setup once, played around with it a bit, and never bothered to put it into production or remove it. ↩︎
