Mount the driver to a container

  1. -v or --volume : contains all fields and also order should be maintained
    • name of the volume
    • path
    • options like ro--(read-only) 
$ sudo docker run -d --volume vol-ubuntu:/tmp ubuntu 14efcc03cc75c98877f1074bc30d3570b4f062c122cccb83272409d677c9ae4c
Enter fullscreen mode Exit fullscreen mode
  1. --mount: Separate fields , and contains as key-value pair, order is not important, easier to understand. 
$ docker service create \ --mount 'type=volume/bind/tempfs,src=<VOLUME-NAME>,dst=<CONTAINER-PATH>,volume-driver=local,volume-opt=type=nfs,volume-opt=device=<nfs-server>:<nfs-path>,"volume-opt=o=addr=<nfs-address>,vers=4,soft,timeo=180,bg,tcp,rw"' --name myservice \ <IMAGE>
Enter fullscreen mode Exit fullscreen mode 
$ sudo docker run -d --name devtest --mount source=myvol2,target=/app nginx:latest 8639e7cc80f422fdbc00b7209a3f976368af7692d38f75b4310b81961c27fc11
