Deploying a web application to Kubernetes involves several key steps. Below is a concise guide to help you get started:
Containerize Your App 📦
Use Docker to create a container image of your web application.
Example command:docker build -t your_app_name .
Push to Container Registry 📤
Upload the Docker image to a registry like Docker Hub or a private registry.docker push your_app_name
Create Kubernetes Deployment File 📄
Define your deployment, service, and ingress in YAML files.
Example snippet:apiVersion: apps/v1 kind: Deployment metadata: name: web-app spec: replicas: 3 selector: matchLabels: app: web-app template: metadata: labels: app: web-app spec: containers: - name: web-app image: your_app_name ports: - containerPort: 80
Apply Configuration 📦
Deploy your app usingkubectl
:kubectl apply -f deployment.yaml kubectl apply -f service.yaml
Expose Service 🔗
Create a service to access your app:apiVersion: v1 kind: Service metadata: name: web-app-service spec: type: LoadBalancer ports: - port: 80 targetPort: 80 selector: app: web-app
Access the app via the service's public IP or domain.
