I am trying to use a nfs shared folder in a raspberry pi running OpenMediaVault as my persistent volume for my app service (docker) running from a ubuntu server. I created the volume first and in my app's compose.yml file, I mentioned this volume as external.
When I try to spin up the container, it fails with the below message -
Code
Error response from daemon: error while mounting volume '/var/lib/docker/volumes/myapp/_data': failed to mount local volume: mount :/export/nfs/docker/volume/myapp_vol:/var/lib/docker/volumes/myapp_vol/_data:/var/lib/docker/volumes/myapp_vol/_data, flags: 0x400, data: addr=192.168.142.123,rsize=8192,wsize=8192,tcp,timeo=14,nfsvers=4: no such file or directory.I also tried a simple mount of the NFS volume (shared folder created as "myapp") from the NFS client -
Code
mount 192.168.142.123:/export/myapp/ /mnt/usb/ -v and this is what I get -
Code

Code
scp test.txt 192.168.142.123:/export/nfs/docker/volume/myapp_vol/Where am I going wrong ? Do I need to have a mount point in the app server and get this nfs volume mounted ?
