PostgreSQL Database
A dedicated PostgreSQL instance is required for JupyterHub operations. The database can be hosted on virtual machines or bare-metal servers.
Hardware Requirements
| Resource | Minimum |
|---|---|
| CPU | 16 cores |
| Memory | 32 GB |
| Storage | 200 GB |
Software Requirements
| Parameter | Requirement |
|---|---|
| PostgreSQL version | 16.0 or higher |
| Maximum connections | 1,000 concurrent connections |
Network Requirements
All Kubernetes worker nodes must be able to reach the PostgreSQL instance over the network.
Usage Notes
- This instance must be exclusively dedicated to JupyterHub -- do not share it with other services.
- The database stores JupyterHub configuration and user notebook data.
- Database provisioning, connectivity, and access management are the responsibility of the tenant.
