Screwdriver
Screwdriver is a continuous delivery platform designed to orchestrate automated build, test, and deployment workflows. It functions as a containerized build orchestrator that manages the entire delivery lifecycle, from event-driven pipeline triggering to the execution of tasks within isolated, pluggable container environments.
The platform distinguishes itself through a modular architecture that decouples build logic from underlying compute resources, allowing for consistent execution across diverse infrastructures. It provides robust pipeline configuration management, enabling teams to define, version, and share reusable build templates. This system is further supported by comprehensive identity services, including OAuth integration and granular access control for pipeline secrets and programmatic tokens.
Beyond core orchestration, the platform offers extensive observability tools, including real-time log streaming, performance metric analysis, and build status tracking. It supports complex team workflows through pipeline collection organization and shared workspaces, while maintaining system stability via request throttling and persistent state management in relational databases.
The system is designed for deployment within Kubernetes clusters, utilizing standardized packaging templates to bootstrap the platform and its required infrastructure components.
