Prerequisites
This is the list of all the prerequisites:
- A Spring Boot project (with Java 17 and Maven 3.8.+)
- kubectl
- A Kubernetes cluster (We’ll use Minikube on our local machine for the first lab.)
- Docker installed
This story starts a new series to learn Kubernetes with Spring Ecosystem.
Overview
What is Kubernetes?
Kubernetes, also known as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery.
Kubernetes Cluster Architecture
A Kubernetes cluster consists of a set of worker machines, called nodes, that run containerized applications. Every cluster has at least one worker node. The worker node(s) host the Pods that are the components of the application workload. The control plane manages the worker nodes and the…
