Adding a data volume

You can add a data volume to a container using the? -v ?flag with the? docker run ?command. You can use the? -v ?multiple times in a single? docker run ?to mount multiple data volumes. Let's mount a single volume now in our web application container.

    
      
        $ sudo docker run ?-P --name web -v ?~/Workspace:/workspace ubuntu
        

        

      
    
  

You can then use the? --volumes-from ?flag to mount the? /dbdata ?volume in another container.

    
      
        $ sudo docker run -it
        
          
            
              --
              
                volumes
                
                  -
                  
                    from
                    
                       workspace -v ~/Workspace ubuntu /bin/bash
