arkade is a command-line tool that functions as a marketplace and installer for developer tools and Kubernetes applications. It provides two primary workflows: downloading CLI binaries (over 200 tools) and installing Kubernetes Helm charts (over 50 apps) with custom overrides. The tool also supports OCI image installation/publishing, Helm chart image version upgrades, system-level package installation (e.g., Node.js, Caddy), and self-updating with SHA-256 verification. The architecture is a monolithic Go CLI built with Cobra, where each subcommand (get, install, update, system, oci, chart, etc.) is a separate command tree. Entry points include main.go (root command) and the various command files under cmd/. External dependencies include GitHub releases API, Helm CLI, kubectl, Docker (for qemu-static), and OCI registries. The codebase demonstrates solid engineering with reusable patterns such as template-based tool definitions, safe archive extraction, and a builder pattern for installer options, though it suffers from a large manual catalog that requires ongoing maintenance.
This repository is a collection of Kubernetes exercises designed for the Certified Kubernetes Application Developer (CKAD) certification preparation. It contains 32 exercises covering core Kubernetes concepts such as pods, deployments, services, volumes, configmaps, secrets, Helm, Kustomize, and more. Each exercise includes instructions and solution files (YAML manifests) that users can apply to a Kubernetes cluster to practice the concepts. The repository also includes a GitHub Actions workflow for validating Kubernetes manifests using kubeconform. While the exercises are well-structured and educational, the codebase primarily consists of static files and exercise-specific configurations with limited reusable components beyond the CI validation workflow.
