Docker Full Course 2026 — AI Summary

Summary

This course provides a structured, hands-on path to mastering Docker, the industry standard for containerization. By building, testing, and deploying applications on AWS, you'll gain the practical infrastructure skills required for modern DevOps, cloud, and software engineering roles.

Key Topics

• Containerization: Unlike VMs that need a full OS, containers share the host kernel. This makes them fast, efficient, and perfectly reproducible across dev, test, and production environments.
• Docker Daemon (dockerd): It listens for API requests from the Docker client and interacts with registries and the host kernel to execute commands, build images, and maintain container life cycles.
• Docker Registry: Docker Hub acts as the public registry where developers pull images like Nginx or Ubuntu, and push their own custom application images for teams to access.

Key Takeaways

• Launch a free-tier Ubuntu EC2 instance on AWS and install the Docker engine.
• Create an IAM role with Systems Manager (SSM) permissions for your EC2 instance.
