Working with a containerized app in dev containers

So far, we've seen how to use a dev container to develop an application, but what if we want to develop an application that will itself be packaged and run in a container, possibly in Kubernetes? In this section, we will focus on that scenario, looking at how to both build and run a container image for our application from inside the dev container.

We will again use the accompanying code for the book as a starting point for this section. Ensure that you clone the code from https://github.com/PacktPublishing/Windows-Subsystem-for-Linux-2-WSL-2-Tips-Tricks-and-Techniques in a Linux distro. Once the code is cloned, open the chapter-10/03-web-app-kind folder in Visual Studio Code (there is also a chapter-10/04-web-app-kind-completed folder with all of the steps from this section applied as a reference). The 03-web-app-kind folder contains a web app very similar to the one we've just been working with, but with a few extra...
