Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications.
Spring Boot is a popular Java framework for building web applications and microservices.
In this post, we'll show you how to deploy a Spring Boot application to Kubernetes.
Create a Kubernetes deployment for your application.
apiVersion: apps/v1
kind: Deployment
metadata:
name: myapp-deployment
spec:
replicas: 3
selector:
matchLabels:
app: myapp
template:
metadata:
labels:
app: myapp
spec:
containers:
- name: myapp-container
image: myapp-image
ports:
- containerPort: 8080
Create a Kubernetes service for your application.
apiVersion: v1
kind: Service
metadata:
name: myapp-service
spec:
type: LoadBalancer
ports:
- port: 80
targetPort: 8080
selector:
app: myapp
Apply the deployment and service to your Kubernetes cluster.
kubectl apply -f myapp-deployment.yaml
kubectl apply -f myapp-service.yaml
Check that the deployment and service are running.
kubectl get deployment
kubectl get service
Your application is now deployed to Kubernetes!
