Harbor is an open-source, cloud-native container registry platform for managing OCI/Docker images, Helm charts, and other artifacts. It provides a full-stack solution with a Go backend, Angular web portal, PostgreSQL database, and Redis/ValKey job queue. The system supports artifact storage, vulnerability scanning (Trivy integration), SBOM generation, multi-registry replication (Docker Hub, Quay, JFrog, cloud CRs), tag retention policies, immutable tags, RBAC with LDAP/OIDC, robot accounts, webhook/notification pipelines, P2P preheat, and audit logging. The architecture follows a layered pattern: REST API handlers (v2.0) → controllers → managers → DAOs, with middleware chains for security, quota, and content trust. Key entry points include the core API server, job service for background tasks, registry controller for blob/manifest management, and the Angular portal for administration. External dependencies include PostgreSQL, Redis, Trivy scanner, and various cloud registry APIs. The codebase is well-structured with extensive unit and integration tests, though it exhibits some technical debt from generated mocks and legacy components.
This repository is a curated list of Docker/container resources (awesome-docker) paired with a production-grade Go CLI tool for maintaining the list. The CLI provides commands for parsing the README, linting entries (alphabetical order, description capitalization, period, duplicates), checking external and GitHub links concurrently, scoring repository health via the GitHub API, generating markdown/JSON health reports, building a static website from the README, an interactive TUI browser, and pruning stale/archived entries from both the README and the health cache. The architecture is modular with clear separation of concerns: parser, linter, checker, scorer, cache, builder, pruner, and TUI packages. The code is well-tested, uses modern Go idioms (Cobra CLI, Bubbletea TUI, GitHub GraphQL API), and is backed by comprehensive CI/CD workflows. The project is actively maintained with frequent commits, dependabot updates, and automated health reports. While the primary value is the curated list, the tooling itself is a high-quality, reusable framework for managing any curated awesome list.
Zarf is an air-gap native package manager for Kubernetes. It provides a CLI tool to build, sign, publish, and deploy immutable software bundles (packages) into disconnected Kubernetes clusters. The architecture consists of a Go CLI that orchestrates package lifecycle (create, deploy, remove, publish, inspect), a mutating admission webhook agent that rewrites container image references and Git URLs to point to internal Zarf services, and a set of embedded tools (Helm, K9s, Syft, Cosign, etc.). Key capabilities include OCI-based package distribution, Helm chart and manifest deployment, Git repository mirroring, SBOM generation, and Cosign-based signing/verification with both key and keyless modes. The codebase is well-structured with extensive unit and e2e tests, a clean separation between API versions (v1alpha1/v1beta1) with bidirectional conversion, and several reusable subsystems for value merging, archive extraction, template processing, and Kubernetes resource waiting. It is actively maintained with frequent releases and a large community (2000+ stars).
This repository is a curated list of Docker Hub mirror URLs for users in China who need accelerated access to Docker images. It provides a table of currently working mirrors, a list of expired ones, configuration instructions for Docker daemon and containerd, and references to self-hosted mirror solutions. The repository contains no application code; it is purely a documentation resource. It is not a software application or data research project; it is a reference list maintained via a single README file.
