Container Internals Lab is an educational repository that provides hands-on learning materials for understanding container technologies and their internal workings. The repository contains structured lab scripts, configuration files, and learning materials organized in a step-by-step format. It includes Dockerfiles for building container images, Makefiles for automation, and OpenShift automated build configurations. The labs are designed to teach fundamental concepts about containers, their architecture, and operational aspects. Content is delivered through ASCII Doc format materials, with additional resources available through the learn-katacoda platform. The repository serves as a practical learning environment for individuals seeking to understand container subsystems, implementation details, and best practices for container deployment and management.
