🔗 Simple network communications in Docker without compose

I often run services like databases or messaging systems in Docker and connect to them from my host computer, where I have a .NET application that processes data. However, managing these services through Docker Compose can add unnecessary complexity when I'm only running a few simple services. In this article, I will show you how to run two applications in Docker, communicating with each other without the need for Docker Compose.

Let's start by creating a simple Docker network that will allow our applications to communicate. We will create two Dockerfiles and a few scripts to manage the containers and run our applications.
