Web Application Updates on Docker

We are experience this with our own web app and even the demo/template here: intersystems-community/iris-fullstack-template: This template shows you how to build, test and deploy a simple full-stack application using InterSystems IRIS REST API (

When changes are made to CSS or HTML files, we can see the changes are saved to file in the Docker container by visiting the command line.  However, after refreshing, clearing cache, etc. the changes don't appear on the web application in the browser.  Viewing the source css in the browser, we see it's the old file.  

Had a minor success where I updated the css and html and upon changing browsers, the css was now updated but the html was the old version.  

Is this a browser issues?  Docker issue? IRIS issue? 

Has anyone experienced this challenge?

@Dmitry Maslennikov This seemed to help as the changes to the HTML are instant with the changed setting, however the CSS didn't change.  After clearing the browser cache then I saw the changes.  Assuming there must be a browser setting that hold on to the CSS.  I'm not sure.  

We haven't quite solved this for our own app.  All the progress thusfar has been in the demo app from GitHub (the coffee shop).
