• Inspecting container state and processes
• Hands-on: Debug a running application inside a container

Module 3: Advanced Dockerfile Patterns

• ARG and ENV for build-time configuration
• HEALTHCHECK instructions
• Signal handling and graceful shutdown
• Hands-on: Build production-ready Dockerfiles with health checks

Day 2: Docker Compose and Multi-Service Apps

Module 4: Docker Compose Deep Dive
