The opencontainers/runtime-tools repository is a command-line application for working with the OCI (Open Container Initiative) runtime specification. It provides two main functionalities: generating OCI runtime spec configuration files (config.json) via the `oci-runtime-tool generate` command, and validating OCI bundles against the runtime specification via the `oci-runtime-tool validate` command. Additionally, it includes a runtime validation suite (`runtimetest`) to test OCI-compliant runtimes (like runC) for specification compliance. The architecture is modular, with separate packages for generation, validation, cgroups handling, path operations, and spec-specific error handling. Built in Go using urfave/cli for command parsing, it supports multiple operating systems (Linux, Windows, Solaris) via build tags and external dependencies on the OCI runtime-spec and other Go libraries. The tool is actively maintained, with recent commits and ongoing alignment with spec updates.
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the repository is actively maintained with yearly architecture documents, the actual scripts and configurations rely on outdated software versions (e.g., Kubernetes 1.18, Docker 18.06, CentOS 7) and external URLs that may become stale.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.
