title: Editing docker volume data on host not changing inside container?
body: <p>I am making application in docker environment. (toolbox)
  I work on the local PC by sharing the volumn.
  When editing a js file, it can not be modified on the website.
  However, I can change the js file to vi in the docker container.</p>
  
  <p>Cache does not seem to be the cause. What is the cause ???</p>
