->A simple explanation of volumes is that it is a way for a containers to interact with the host's filesystem. This is useful in several situations; persisting data that you don't want lost if the container were to stop unexpectedly, as a communication method between otherwise isolated containers, and (as in our case) having our container reference rapidly changing source code on our host.
