Course 31 - Dive Into Docker | Episode 8: Networking, Persistence, and System Optimization

About this episode

This episode covers advanced Docker concepts including networking, data persistence, and image optimization techniques.

In this lesson, you’ll learn about: advanced Docker architecture, networking, persistence, and image optimization1. 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🔹…
