title: Persist multiple directories inside docker container into single volume
body: <p>We have  our services running inside container and with current implementation we are storing
  data into multiple directories inside container like (/root/data1 , /var/some_Dir/ , /opt/some_dir).</p>
  
  <p>in order to persist all this data i am passing multiple " -v  "  for each directory. 
   But i want to do this using single "-v"  (volume ) option.</p>
  
  <p>Though I can put all my data  in single location  and persist  that  directory with single "-v" option.</p>
  
  <p>is  there any other option for persisting multiple  directories in single volume ??????</p>
  
  <p>what i am using right now is ::</p>
  
  <p>docker run  -v /hostdir/1:/root/dir1  -v /hostdir/2:/var/lib/dir1. -v /hostdir/3:/opt/dir3 ........     -v /hostdir/10:/opt/dir4/logs. </p>
  
  <p>i want to shorten it single "-v" option. no need to give "-v" 10 times. </p>
