Getting Started

1. Clone this repository:

git clone https://github.com/ClinicianFOCUS/local-llm-container.git
cd local-llm-container

docker-compose up -d

Launching Models

After container deployment, you can launch models using either the CLI or API:

Using CLI

1. Connect to the Ollama container:

docker exec -it ollama-service bash

2. Pull your desired model:

ollama pull gemma2:2b-instruct-q8_0
# or any other model

3. Run the model:

ollama run gemma2:2b-instruct-q8_0

Using API

1. Pull a model via API:

curl -X POST http://localhost:3334/api/pull \
     -H "Content-Type: application/json" \
     -d '{"name": "gemma2:2b-instruct-q8_0"}'

2. Generate with the model:

curl -X POST http://localhost:3334/api/generate \
     -H "Content-Type: application/json" \
     -d '{
           "model": "gemma2:2b-instruct-q8_0",
           "prompt": "Your prompt here"
         }'
