title: how to containerize a part of application
body: <p>I am working on a POC where I had to containerize a part of application for eg - I need to containerize  &quot;add to cart&quot; functionality in an e-commerce website, I see a various example <a href="https://dzone.com/articles/docker-for-devs-containerizing-your-application" rel="nofollow noreferrer">https://dzone.com/articles/docker-for-devs-containerizing-your-application</a>  to containerize whole application,but how to do for a part of it where my functionalities has dependency on other code parts as well.</p>
