NFS in Docker-Compose

My main Docker deployments are on a single linux server. I have a central ‘data’ directory where I keep my common data. The application specific data or settings are stored in /srv/.

But for testing or demos I am usually using local Docker installations on my McBook or McBook Air under OS/X. I am using NFS to access the shared central data.

In this Blog I give a quick overview of the setup:

• Install the NFS Server. There are plenty of good tutorials on the Internet that describe how to do this. I was using this. It would even be an option to run the NFS Server as Docker Container.

• Create Exports for the Directories on the Server. Fortunately I could use the NFS Exports screen from Webmin. Here is the definition for sharing the /srv directory:
  

I am using a Zerotier virtual Network so that I can access my local resources also from the public Internet. Therefore I was defining the corresponding IP network and netmask.

• Now we are ready to use the exported directories. Here is the docker-compose.yml file which is using NFS volumes:

  version: '3.2'
  services:
    beakerx:
      image: pschatzmann/data-science:1.2.0
      container_name: beakerx
      hostname: beakerx
      restart: always
      ports:
        - 8007:8888
        - 9000:9000
      volumes:
        - nfs-srv:/home/beakerx
        - nfs-data:/data
      environment:
        - TZ=Europe/Zurich
      dns:
        - 8.8.8.8
      extra_hosts:
        - "nuc.local:10.147.17.177"
  
  volumes:
    nfs-srv:
       driver: local
       driver_opts:
         type: nfs
         device: ":/srv/data-science"
         o: "addr=10.147.17.177,nolock,soft,rw"
  
    nfs-data:
       driver: local
       driver_opts:
         type: nfs
         device: ":/data"
         o: "addr=10.147.17.177,nolock,soft,rw"
