Learn DRONE-CI with Real Code Examples
Updated Nov 27, 2025
Architecture
Drone server handles pipeline orchestration and API
Agents execute steps as Docker containers
Steps run in ephemeral containers with defined images
Secrets and environment variables injected securely
Pipeline triggered via SCM events, cron, or manual triggers
Rendering Model
.drone.yml -> Parse -> Steps -> Services -> Agents execute -> Logs/Notifications
Steps run in ephemeral containers
Secrets injected securely at runtime
Supports sequential and parallel execution
Artifacts stored or deployed externally
