Spring Boot Microservices , Docker and Kubernetes workshop – part3

In the previous posts we build few micro services (Order Service, Product Service, Customer Service) for an order management system using Docker and Spring Boot. We used Netflix libraries to manage, discover and load balance the micro services.

Managing these micro services and their multiple containers could get a bit tricky; especially in terms of Scalability, Observability, Security, Monitoring and managing resources. Hence we would use Kubernetes for our container orchestration. Click here to read more about Kubernetes.

In order to get started, we could either use a local Kube cluster in the laptop or use a cloud provider like AWS/Azure/GCP.

Spring Boot Microservices , Docker and Kubernetes workshop – part2

In the previous post we created our first micro service “ProductService” using SpringBoot and Docker.

In this part we will go into details of how to manage multiple microservices using Spring Cloud and netflix libraries.

For our order management system, let’s say,  a minimal relationship could be something like this :

So, let’s build 2 more services called “orderService” and “customerService” in the similar manner how we build the “productService”.

Spring Boot Microservices , Docker and Kubernetes workshop – part1

In this series of workshop we will build few micro services using spring boot, docker and then deploy them into kubernetes.
So, Lets get started.

First we need to define a problem statement to begin with. Let’s say we want to build an order management system.

Identifying domains

First step would be to understand what domains are required, for simplicity lets assume we need the following domains:
