Implementation Guide

1. Container Strategy


services:
  auth-service:
    port: 3001
    dependencies:
      - user-db
  user-service:
    port: 3002
    dependencies:
      - user-db
  product-service:
    port: 3003
    dependencies:
      - product-db

2. Kubernetes Deployment


apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp
spec:
  replicas: 3
  selector:
    matchLabels:
      app: myapp
  template:
    metadata:
      labels:
        app: myapp
    spec:
      containers:
      - name: myapp
        image: myapp:1.0.0
