The platform itself
| Resource | Covers |
|---|---|
| DAReHub/DAReflow | The DARe prototype orchestration platform |
This is the repository the Deployment Server pulls from, described in architecture. It is the primary reference for this chapter, and the only external source the handbook cites for it.
Technologies used
The platform is assembled from established open-source components. Their own documentation is the best reference for each:
| Technology | Role in the platform | Covered on |
|---|---|---|
| Apache Airflow | Authoring, scheduling and monitoring workflows as DAGs | Airflow |
| Docker | Containerising model applications | Docker |
| MinIO | Locally hosted object storage, S3 compatible | Data storage |
| PostgreSQL | Metadata storage | Data storage |
| Git | Version control and lineage | Version control |
Points to resolve in the source
Three items should be addressed before publication:
- "Direct Acyclic Graphs" appears in this chapter, while the Introduction uses the standard term "directed acyclic graphs". The latter is correct and is used throughout these pages.
- Encryption at rest and the external backup server appear only in the architecture diagram, not in the chapter text, despite being operationally significant.
- Both figures are captioned "Figure X" in the source, with no numbering. They are numbered 3 and 4 here, continuing from the Introduction's figures.
