Declaring Docker volumes on Compose files

We’ve been able to create a Docker volume and use it, and had a look at its features. The step next is to create and use volumes using Compose. Volumes on Compose are defined in the volumes sections:

services:
  nginx:
    image: nginx
volumes:
  example-compose-volume:

The configuration option on volumes can apply to example labels:

services:
  nginx:
    image: nginx
volumes:
  example-compose-volume:
    labels:
      - com.packtpub.compose.app=volume-example

Alternatively, you can have more advanced configurations, for example, a driver that is configured to use nfs:

services:
volumes:
  nfsvol: 
    driver_opts: 
      type: "nfs" 
      o: "addr=127.0.0.1,nolock,rw" 
  ...
