DDS Dev Stack

Reusable Docker-based development stack for Dunked Digital Solutions.

Services

Service	Purpose	URL / Port
Open WebUI	Local AI chat interface	http://localhost:3001
ChromaDB	Vector database / RAG storage	http://localhost:8000
PostgreSQL	Main database	localhost:5433
pgAdmin	PostgreSQL web admin	http://localhost:5050

Requirements

• Docker
• Docker Compose
• Ollama installed on the host machine if using local models

Setup

Copy the example environment file:

cp .env.example .env

Start the stack:

./scripts/start.sh

Check status:

./scripts/status.sh

Stop the stack:

./scripts/stop.sh

Ollama

This stack connects Open WebUI to Ollama running on the host machine.

Open WebUI uses:

http://host.docker.internal:11434

This avoids downloading duplicate models inside Docker.

Ports

PostgreSQL uses host port 5433 to avoid conflicts with an existing local PostgreSQL installation on 5432.

Notes

The data/ directory is ignored by Git and stores local container data.

Optional Docker Ollama

By default, this stack uses Ollama installed on the host machine.

If you do not have Ollama installed locally, you can start the stack with the optional Docker Ollama service:

docker compose -f docker-compose.yml -f docker-compose.ollama.yml up -d

Docker Ollama is exposed on:

http://localhost:11435

This avoids conflicting with a host Ollama installation that usually runs on:

http://localhost:11434

To pull a model into Docker Ollama:

docker exec -it dds-ollama ollama pull qwen2.5:7b

Dockge

This stack can be managed through Dockge when placed inside the DDS stacks folder.

Expected DDS workspace structure:

/home/duncan/Work/DDS/
├── stacks/
│   ├── dds-dev-stack/
│   └── dockge/
├── templates/
├── clients/
├── docs/
└── projects/

Dockge URL:

http://localhost:5001

Dockge stacks path:

/home/duncan/Work/DDS/stacks

You can still manage this stack directly with Docker Compose or the helper scripts.
