Summary
In this lesson, you’ll learn about: Docker Compose workflows, API versions, and real-world microservices orchestration1. Essential Docker Compose Commands & WorkflowUsing Docker Compose, you can manage your entire application lifecycle with a few commands:🔹 Core Commands docker-compose up → Start services docker-compose build → Build images docker-compose stop → Stop containers docker-compose ps → List running containers docker-compose logs → View logs ⚡ Efficient Development Shortcutdocker-compose up --build -d Builds images Pulls dependencies Starts everything in detached mode 👉 This is the most commonly used real-world command🔹 Scaling Servicesdocker-compose up --scale web=3 Runs multiple instances of a service Useful for: Load balancing Testing distributed systems 🔹 Overriding Dockerfile Behaviorcommand: python worker.py Overrides CMD from Dockerfile Lets you reuse the same image for: Web server Background worker Scheduler 2. API Versions & Evolution Docker Compose started as: Fig (community project) 🔹 Version ComparisonVersionKey Featuresv1Legacy, no service/network namespacesv2Introduced networks, volumes improvementsv3Modern standard, supports scaling & orchestration✅ Recommended Versionversion: "3" Compatible with modern Docker Required for newer features 3. Real-World Microservices Case StudyA complex voting app built with multiple technologies: Flask → frontend Node.js → API layer .NET → worker service Redis → queue/cache PostgreSQL → database 4. Multi-Tier Networking Services are split into: Front-tier → user-facing Back-tier → internal services networks: front-tier: back-tier: 👉 Improves: Security Isolation Traffic control 5. Volume Strategies🔹 For Interpreted Languages (Flask, Node.js) Use host-mounted volumes Enables: Live code updates No rebu…
