Oxide CI is composed of several modular crates.

Defines the shared types, events, and logic used across the system. This includes the PipelineDefinition struct, event bus traits, and basic utilities.

The worker component responsible for executing jobs. It listens for commands from the scheduler and runs steps.

Orchestrates pipeline execution. It resolves the DAG (Directed Acyclic Graph) of stages and dispatches jobs to available agents.

The execution engine that runs individual steps. It handles:

• Docker container lifecycle (testcontainers, docker).
• Process isolation.
• Plugin execution.

See Plugin System.

• PostgreSQL: Stores pipeline definitions, run history, and logs.
• MinIO/S3: Stores artifacts and cache blobs.
• NATS: Event bus for real-time communication between components.
