Kube By Example – Spring Boot Microservices on Kubernetes

Kubernetes is a container orchestration system used to automate software deployment, scaling, and management.

Effectively, Kubernetes is a management tool that directs the running of Docker images.

The services communicate via RESTful APIs or JMS messages.

You will learn how to compose each service into a Kubernetes Deployment. And then use Kubernetes Services to expose the microservices to each other.

With Kubernetes, it is a best practice to configure Readiness and Liveness probes. Since our services are persisting data, we will also configure a graceful shutdown to prevent any data loss.

One common issue with Microservices is logging. Each running instance will generate its own log output. Thus, it is common to use consolidated logging.

A very common approach is to use the ELK stack (Elasticsearch, Logstash, Kibana). Elasticsearch is a full-text search engine. Logstash is used to get log data into a common format for Elasticsearch. And Kibana is a powerful data visualization engine. Together, these tools allow you to consolidate and search through your log data.
