To deploy a Docker image in Minikube, you can follow these steps:

  1. Start Minikube: minikube start
  2. Set Docker environment variables to use Minikube's Docker daemon: eval $(minikube docker-env)
  3. Build your Docker image: docker build -t your-image-name:your-tag .
  4. Deploy your Docker image using a Kubernetes Deployment manifest. Save the following YAML as deployment.yaml: apiVersion: apps/v1 kind: Deployment metadata: name: your-deployment-name spec: replicas: 1 selector: matchLabels: app: your-app-label template: metadata: labels: app: your-app-label spec: containers: - name: your-container-name image: your-image-name:your-tag ports: - containerPort: 8080 # Replace with the port your app listens on
  5. Apply the deployment manifest to create the Deployment and Pods: kubectl apply -f deployment.yaml
  6. Optionally, verify the deployment: kubectl get deployments kubectl get pods
  7. Expose your app using a Service manifest. Save the following YAML as service.yaml: apiVersion: v1 kind: Service metadata: name: your-service-name spec: selector: app: your-app-label ports: - protocol: TCP port: 80 targetPort: 8080 # Replace with the port your app listens on type: LoadBalancer # Or NodePort, ClusterIP, etc. based on your requirements
  8. Apply the service manifest to expose your app: kubectl apply -f service.yaml


Now, your Docker image should be deployed and accessible within Minikube using the specified Service. You can access your app using the Minikube IP and the exposed port.
