Containerization and Local Environment Setup

So far, we have seen that our modular solution design, with services implementing the Single Responsibility Principle (SRP), can quickly lead to a wealth of running components within our application. Working on these as a single contributor could be overwhelming, and working on isolated domain teams may lead to hiccups when performing integration testing. Establishing a pattern that will address the potential for issues during integration, along with a lower barrier to entry for developers, can pay huge dividends down the road. Throughout this chapter, we will be doing just that—setting up a pattern for usage and deployment that will carry on across developer environments and, ultimately, to production.

Throughout this chapter, we will be doing the following:

• Reviewing containerization fundamentals
• Setting up the local environment
• Using Dockerfiles to build and run locally

By the end of this chapter, you...
