local machine issues with docker

The docker system in which docker is installed or running can run into dangling state. 

   To check whats the disk consumption due to Docker 
    docker system df 
    
    Primarily the issues comes up is with low disk space. Of course this is re-claimable.      
        
    Cause for Low disk space are 
    (a) docker images created during build could be in dangling state
                                      or would have been stored or persisted for a longer time. 
    check >>> docker images
          >>> docker images prune // resolves by removing the images which are in dangling state. 
    
    (b) docker containers created during build for certain deployments could be in dangling state
                                      or would have been stored or persisted for a longer time. 
    check >>> docker containers
          >>> docker containers prune // resolves by removing the containers which are in dangling state/ or no more used.                                      
               
    (c) docker volumes created during build for storing some data which would have been in needed for all further 
                                      deployments could be causing as it can grow. 
                                       
    check >>> docker volume
          >>> docker volume prune // resolves by removing the volumes which are in dangling state/ or no more used.
