Deploying a Node.js Application with Kustomize on Minikube
- This article discusses deploying a Node.js application using Kustomize on a Minikube cluster, covering project structure, Dockerfile setup, Kubernetes manifests, and configuration management for different environments.
- Prerequisites include Docker, Minikube, and kubectl installed on the machine.
- The project structure includes config files, Kubernetes manifests, app.js, Dockerfile, and directories for overlays in different environments.
- The app.js file contains code for a Node.js application that reads config settings and displays them dynamically.
- The Dockerfile sets up the Node.js application with build and production stages for deployment.
- Building and pushing the Docker image to Docker Hub involves using 'docker build' and 'docker push' commands.
- Kubernetes manifests are organized into base (common configs) and overlays (environment-specific configs) directories.
- Kustomize is highlighted for declarative management, environment-specific configurations, no templating, and integration with kubectl.
- Advantages of Kustomize are discussed, and alternatives like Helm and Ksonnet are mentioned.
- Steps to deploy the application on Minikube include starting Minikube, deploying to Kubernetes with specific configurations, testing the app, and verifying deployments.
