Curriculum

Orchestration Mastery

Dive deep into Docker Swarm and Kubernetes orchestration. This section provides extensive practice on deploying, managing, scaling, and efficiently troubleshooting complex containerized applications across these critical platforms. Learners will tackle scenarios involving service creation, stack deployment, node management, and cluster health monitoring to ensure robust container orchestration capabilities.

Image Lifecycle & Registry Management

Focus on the entire lifecycle of Docker images. This section covers best practices for building optimized and secure container images, managing their versions, handling layers, and interacting with private and public registries. Practice questions will challenge your knowledge of Dockerfiles, multi-stage builds, image tagging, pushing, pulling, and implementing content trust for secure image distribution.

Installation & Configuration Essentials

This part of the curriculum addresses the foundational aspects of setting up and configuring Docker environments. You'll practice installing and troubleshooting Docker Engine, Universal Control Plane (UCP), and Docker Trusted Registry (DTR) in various deployment models, including cloud-based and on-premise infrastructures. Topics include daemon configuration, system requirements, and component integration for a robust Docker setup.

Advanced Docker Networking

Explore the intricacies of Docker's networking capabilities. This section delves into configuring various network drivers (bridge, host, none, overlay), understanding ingress and egress traffic, implementing service discovery, and setting up Kubernetes service networking for seamless container communication. Practice questions will cover network creation, connection, inspection, and troubleshooting common connectivity issues in complex Docker deployments.

Container Security Best Practices

Learn to secure your Docker environments effectively. This section focuses on implementing crucial security measures, including image signing and verification, understanding and applying role-based access control (RBAC), and establishing secure communication channels within Docker deployments. Topics include secrets management, security scanning, and user management to protect your containerized applications.

Storage Management & Persistence

Master the critical aspect of persistent storage for containers. This section covers different Docker storage drivers, managing volumes (bind mounts, named volumes), and configuring persistent storage solutions for both individual Docker containers and Kubernetes pods. Practice will involve data persistence strategies, volume backups, and selecting appropriate storage drivers for optimal performance and data integrity.
