meteor-kubernetes-guide

This guide provides a practical walkthrough for deploying Meteor applications on Kubernetes, addressing common scaling and deployment challenges in production environments. It covers containerization, cluster configuration, secrets management, and service exposure, enabling developers to leverage Kubernetes' orchestration capabilities for Meteor apps.

Key Features

• Docker Image Creation — Uses specialized Meteor base images and custom Dockerfiles to containerize applications.
• Kubernetes Cluster Setup — Instructions for creating and managing clusters, including cloud provider integration.
• Secrets Management — Securely handles environment variables, Docker registry credentials, and sensitive data via Kubernetes Secrets.
• Deployment Configuration — Defines YAML-based deployments for app instances, replica sets, and rolling updates.
• Auto-scaling — Configures HorizontalPodAutoscaler to adjust pod count based on CPU utilization.
• Service and Ingress — Sets up services for internal routing and nginx-based ingress controllers for external access with load balancing.
• HTTPS Support — Guides for custom TLS certificates and integration with Let's Encrypt via Cert-Manager.

Philosophy

The guide emphasizes a declarative, infrastructure-as-code approach, using YAML configurations to manage deployments and promote reproducibility. It focuses on practical, step-by-step instructions to make Kubernetes accessible for Meteor developers without requiring deep prior knowledge.
