cross-rs/cross is a CLI tool that enables zero-setup cross-compilation for Rust projects by wrapping Cargo and executing builds inside container engines (Docker/Podman). It manages a comprehensive registry of pre-built Docker images for dozens of target triples (Linux, musl, Android, FreeBSD, NetBSD, Solaris, Windows, bare-metal, etc.), automatically selects the appropriate image based on the --target flag, mounts the project source and toolchain, and runs cargo build/test inside the container. The tool also supports remote Docker execution, custom Dockerfiles, and advanced configuration via Cross.toml and environment variables. The codebase is structured as a Rust CLI with two binaries (cross and cross-util), a library of container orchestration modules, and a developer xtask workspace for CI, codegen, and changelog management. It demonstrates strong engineering practices with extensive CI, testing, and reusable patterns for command execution, container abstraction, and configuration merging. The repository includes a large collection of Dockerfiles and shell scripts for building target-specific toolchain images, as well as CI workflows that test across many platforms and container engines.
Buildah is a command-line tool for building OCI-compliant container images without requiring a daemon. It focuses on image creation tasks such as building from Dockerfiles/Containerfiles, managing working containers, committing images, and pushing/pulling to registries. The architecture is modular, separating CLI command handling (using Cobra), core build logic, storage abstraction, and utility packages. Key features include rootless operation, multi-platform support (Linux/FreeBSD), SBOM generation, and confidential workload encryption via SEV/SNP. The tool is designed for integration with container ecosystems like Podman and Kubernetes, emphasizing security and flexibility in image building workflows.
This repository is a comprehensive, declarative NixOS homelab configuration managed with the Clan framework. It defines the entire infrastructure for a multi-machine homelab including servers, desktops, and network devices, all version-controlled and reproducible. The system provisions self-hosted services (Caddy, Grafana, VictoriaMetrics, Vector, Blocky, Miniflux, Linkding, etc.), identity management (Authentik, Zitadel), monitoring and alerting, backup (Borgbackup), and desktop environments (KDE, i3). The architecture is modular: reusable NixOS feature modules under `modules/nixos/features/` follow a consistent pattern using `mkFeatureOptions` for enabling services with standardized options (domain, firewall, monitoring integration). Secrets are managed via SOPS with age encryption, and disk partitioning is handled by Disko templates. The repository is not a software application but an infrastructure-as-code project that demonstrates high craftsmanship in Nix module design, with clear separation of concerns, helper functions, and integration patterns. It is actively maintained but shows some technical drift due to deprecated identity providers and hardcoded IPs.
