As microservices systems expand beyond a handful of services, we often need some way to coordinate everything and ensure consistent communication (avoid human error). Tools such as Kubernetes or Docker Compose have quickly become commonplace for these types of workloads. Today’s example will use Docker Compose.
Docker Compose is an orchestration tool that manages containerized applications, and while I have heard many lament the complexity of Kubernetes, I found Docker Compose to have some complexities as well. We will work through these along the way and explain how I solved them.
