Container Networking & Service CommunicationYou move deeper into Docker networking by connecting multiple containers together.🔹 Default vs Custom Networks Default bridge network: Basic isolation Requires manual IP handling Custom bridge network (recommended): Automatic DNS resolution Containers communicate by name (e.g., redis, db) docker network create my-network 🔹 Why this mattersInstead of:http://172.18.0.3:6379 You can use:redis:6379 👉 Much more stable and production-ready2. Sharing Data Between Containers🔹 Volumes Between Containers Use shared storage with: VOLUME instruction --volumes-from docker run --volumes-from container1 container2 🔹 Use Case Sharing: static files logs shared assets 3. Data Persistence with Named Volumes🔹 Problem Containers are ephemeral Data disappears when container is removed 🔹 Solution: Named Volumesdocker volume create app-data Managed internally by Docker Stored outside container lifecycle 🔹 Benefits Survives: container deletion restarts Ideal for: databases user data stateful apps 4. Image Optimization Techniques🔹 Reduce Build ContextUse .dockerignore:node_modules .env .git Prevents unnecessary files from being copied Improves build speed Reduces image size 🔹 Remove Build Dependencies Install build tools temporarily Remove them after build 👉 Results in significantly smaller images5. Advanced Startup Logic (ENTRYPOINT)🔹 Purpose Run scripts before main container starts ENTRYPOINT [\"/start.sh\"] 🔹 Use Cases Environment setup Database migrations Dynamic configuration 6. System Maintenance & Cleanup🔹 Check Disk Usagedocker system df 🔹 Clean Unused Resourcesdocker system prune Removes: stopped containers unused networks…","meta_description":"In this lesson, you’ll learn about: advanced Docker architecture, networking, persistence, and image optimization1.
