Overview

PostgreSQL 17 with pgvector extension for Sim Studio vector embeddings and semantic search. This is the required database backend for Sim Studio. pgvector enables fast similarity search on embeddings and is essential for AI-powered features like semantic search and vector similarity matching in Sim Studio.

Install simstudio-db on Unraid in a few clicks.

Find simstudio-db in Community Apps on your Unraid server, review the template, and click Install. Unraid handles the Docker app or plugin setup from the published template.

Requirements

Database files must reside on locally attached storage (SSD/NVMe recommended), not on remote-mounted filesystems. Used as the database backend for simstudio and realtime services.

IMPORTANT: Before adding this container, you must create the Docker network 'simstudio_internal' first. Follow these steps in Unraid:

Open Terminal (Go to Main, click Terminal button)
Run: docker network create simstudio_internal
Go to Settings > Docker
Set "Enable Docker" to "No" and click Apply
Set "Preserve user defined networks" to "Yes" and click Apply
Set "Enable Docker" to "Yes" and click Apply
The network is now ready for use with all Sim Studio containers
