This repository is a companion to the Korean book '컨ν μ΄λ μΈνλΌ νκ²½ ꡬμΆμ μν μΏ λ²λ€ν°μ€/λ컀' (Kubernetes/Docker for Container Infrastructure). It provides a collection of Vagrant-based lab environments, shell provisioning scripts, Kubernetes YAML manifests, Helm charts, and CI/CD examples (Jenkins) to help readers build and manage Kubernetes clusters on VirtualBox. The codebase includes single-master and multi-master (via Kubespray) cluster setups, along with demonstrations of core Kubernetes concepts (Pods, Services, Ingress, Storage, Monitoring). While the repository is actively maintained with yearly architecture documents, the actual scripts and configurations rely on outdated software versions (e.g., Kubernetes 1.18, Docker 18.06, CentOS 7) and external URLs that may become stale. The code is functional for educational purposes but is boilerplate-heavy and repetitive across chapters, limiting its reusability in production environments.
The LLM identified 1 files worth highlighting for reuse:
A shell script that defines a comprehensive set of kubectl aliases (e.g., kgp for get pods, keq for exec -it) and helper functions for Kubernetes cluster management. It is self-contained, requires no internal dependencies, and can be sourced in any Kubernetes environment to improve command-line efficiency. This is a reusable pattern for any engineer working with kubectl.
