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:
