container image registry with identity management

Harbor is a self-hosted, enterprise-grade container registry platform designed to store, sign, and scan container images and cloud-native artifacts. It provides a centralized repository that integrates directly with Kubernetes environments to manage the full lifecycle of software artifacts, from initial storage to production deployment. The platform distinguishes itself through a focus on security, governance, and multi-site availability. It features a pluggable vulnerability scanning framework that allows for the integration of various security engines, alongside content trust mechanisms tha

Distribution is an open-source container image registry that implements the OCI Distribution Specification, enabling any OCI-compatible client to push, pull, and manage container images over standard protocols. It serves as a content distribution toolkit for packaging, shipping, storing, and delivering container content across networked environments, storing and retrieving content by its cryptographic hash for integrity and deduplication. The registry separates image metadata from bulk data to enable efficient validation and partial pulls, and supports resumable blob uploads with chunked tran

Clair is a container image vulnerability scanner and security analyzer. It performs static analysis of container images by matching package contents against vulnerability databases to identify security risks across different package formats and architectures. The project functions as both an image indexer and a vulnerability database manager. It processes container layers into intermediate representations to enable fast security lookups and synchronizes security metadata from multiple external sources to maintain a local registry. Capability areas include continuous security monitoring, whic

Docker is an OCI container engine and runtime orchestrator used to build, run, and manage isolated applications. It functions as a container image builder for creating portable snapshots of applications and a registry manager for storing, versioning, and distributing those images across environments. The platform provides a centralized daemon to control the creation, execution, and termination of containerized workloads. It allows for the assembly of modular container systems by combining build tools, registries, and runtimes. Its core capabilities cover container image creation, registry ad

Komodo is a remote server orchestrator and container deployment platform. It provides a centralized interface for managing multiple remote hosts through lightweight agents, coordinating Docker Swarm and Kubernetes clusters, and automating software delivery via integrated CI/CD pipelines. The system distinguishes itself with a TypeScript-based automation engine that executes typed scripts against the system API for complex operational workflows. It supports infrastructure-as-code through TOML-based declarative configuration synchronization and provides ephemeral build infrastructure that provi
