Topic	Topics Covered	Labs
Introduction to Docker	- What is Docker, and why use it? - Key concepts: Images, Containers, Registries, Orchestration - Docker ecosystem	- Install Docker on your system. - Run your first container and explore basic Docker CLI commands.
Building Docker Images	- Writing Dockerfiles and best practices - Multi-stage builds - Tagging and pushing images to a registry	- Create a Dockerfile for a simple app (e.g., Flask/Node.js). - Build, tag, and push the image to a registry.
Networking & Storage	- Docker networking: Bridge, host, and overlay - Persistent storage: Bind mounts vs. named volumes	- Create a custom network for containers. - Use volumes to persist data for a database container.
Orchestration	- Overview and use cases of Docker Compose - Defining multi-service applications in docker-compose.yml	- Write a docker-compose.yml file for a web app with a database. - Deploy the app using Docker Compose.
Production Best Practices	- Security best practices (e.g., non-root users) - Optimizing images - Resource constraints: CPU and memory	- Create a secure Dockerfile using non-root users. - Configure resource limits for a container.
Debugging & Logging	- Inspecting containers and troubleshooting - Managing logs and integrating with logging tools (e.g., Loki)	- Debug a broken containerized app. - Forward logs to a logging tool.
Advanced Topics	- Multi-architecture builds with Buildx - Docker Swarm or Kubernetes basics - CI/CD pipeline integration	- Build a multi-architecture image. - Set up a CI/CD pipeline to build and deploy a Dockerized app.
Wrap-Up & Evaluation	- Review of key concepts - Q&A and participant feedback	- Final project: Deploy a full-stack app using Docker Compose.
