⚙️ Deployment Configurations

The lists below match the environment variables forwarded in this repository’s docker-compose.yml (production, production-gpu, development, and development-gpu). Put values in a .env file next to the compose file, or export them before docker compose up. The Electron app backend can read the same names when run outside Docker.

Other optional variables exist in code (for example advanced Mem0 paths, LiteParse runners, or FAST_API_INTERNAL_URL when Next.js and FastAPI are not same-origin); they are not wired in docker-compose.yml. Supported names are discoverable from servers/fastapi/utils/get_env.py and the Next.js server utilities under servers/nextjs/.

Ollama

Use when LLM is ollama:

• OLLAMA_URL: Base URL of the Ollama HTTP API (e.g. http://host.docker.internal:11434 from Docker).
• OLLAMA_MODEL: Model name in Ollama (e.g. llama3.2:3b).
• START_OLLAMA=[true/false]: Container entrypoint (start.js): optional install + ollama serve. Default false (development / production compose).

Presentation memory (Mem0 OSS)

Mem0 uses local Qdrant + SQLite (OSS); memory is scoped per presentation.

By default the Docker runtime now points Mem0 at a local Ollama-compatible LLM endpoint, so it no longer needs an OpenAI key just to initialize. If you want to use OpenAI instead, set MEM0_LLM_BASE_URL/MEM0_LLM_API_KEY to your OpenAI-compatible endpoint and key.
Docker images install the default spaCy model (en_core_web_sm) during build so Mem0 can start without extra setup on each run.

Document parsing (LiteParse)

Database

• DATABASE_URL: SQLAlchemy URL; if unset, the app falls back to SQLite under app data.
• MIGRATE_DATABASE_ON_STARTUP: Compose sets true for all services so migrations run on startup.

Image generation

These variables match docker-compose.yml. IMAGE_PROVIDER selects the backend (pexels, pixabay, gemini_flash, nanobanana_pro, dall-e-3, gpt-image-1.5, comfyui, open_webui). Use OPENAI_API_KEY for OpenAI image modes and GOOGLE_API_KEY for Gemini image modes (same keys as the LLM section).

• DISABLE_IMAGE_GENERATION=[true/false]: Disable slide image generation.
• IMAGE_PROVIDER: Provider id (see enum above).
• PEXELS_API_KEY: Pexels stock images.
• PIXABAY_API_KEY: Pixabay stock images.
• DALL_E_3_QUALITY=[standard/hd]: Optional for dall-e-3 (default standard).
• GPT_IMAGE_1_5_QUALITY=[low/medium/high]: Optional for gpt-image-1.5 (default medium).
• COMFYUI_URL / COMFYUI_WORKFLOW: Self-hosted ComfyUI workflow JSON.
• OPEN_WEBUI_IMAGE_URL / OPEN_WEBUI_IMAGE_API_KEY: Open WebUI–compatible image endpoint.
• OPENAI_COMPAT_IMAGE_BASE_URL / OPENAI_COMPAT_IMAGE_API_KEY / OPENAI_COMPAT_IMAGE_MODEL: Required if using openai_compatible to send image requests to any OpenAI-compatible /v1/images/* endpoint (LiteLLM, Azure, vLLM Gateways, etc.).

Telemetry

• DISABLE_ANONYMOUS_TRACKING=[true/false]: Set to true to disable anonymous telemetry.

Authentication (web login)

Presenton uses a single admin account per instance. Credentials live in app_data (hashed; see userConfig.json). Pass these with -e or via .env for compose:

• AUTH_USERNAME / AUTH_PASSWORD — Preseed the admin login on first boot (password at least 6 characters). Ignored if a user already exists unless AUTH_OVERRIDE_FROM_ENV is set.
• AUTH_OVERRIDE_FROM_ENV=[true/false] — If true, replace stored credentials from the env vars on every FastAPI startup and rotate the session signing secret (invalidates existing sessions). Remove after a one-off rotation.
• RESET_AUTH=[true/false] — If true, clear stored credentials on startup. Use for a single boot to recover access, then unset.

Examples

docker run -it --name presenton -p 5001:80 -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest

docker run -it --name presenton -p 5001:80 -e AUTH_USERNAME=admin -e AUTH_PASSWORD=changeme123 -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest

docker run -it --name presenton -p 5001:80 -e AUTH_USERNAME=admin -e AUTH_PASSWORD=changeme123 -v "${PWD}\app_data:/app_data" ghcr.io/presenton/presenton:latest

docker stop presenton && docker rm presenton && docker run -it --name presenton -p 5001:80 -e AUTH_USERNAME=admin -e AUTH_PASSWORD=newcred456 -e AUTH_OVERRIDE_FROM_ENV=true -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest

docker stop presenton && docker rm presenton && docker run -it --name presenton -p 5001:80 -e RESET_AUTH=true -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest

docker stop presenton && docker rm presenton && docker run -it --name presenton -p 5001:80 -e AUTH_USERNAME=admin -e AUTH_PASSWORD=changeme123 -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest

Manual reset: stop the container, edit ./app_data/userConfig.json, delete AUTH_USERNAME, AUTH_PASSWORD_HASH, and AUTH_SECRET_KEY, save, and start again.

Sign out from the app: Settings → Other → Sign out.

MCP authentication

When auth is configured (AUTH_USERNAME / AUTH_PASSWORD), the MCP endpoint at /mcp now requires authentication as well.

1. Log in once to get a bearer token:

curl -s -X POST http://localhost:5001/api/v1/auth/login \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"changeme123"}'

The response includes:

• access_token (session token)
• token_type (bearer)

1. Configure your MCP client to send that token on every request:

{
  "mcpServers": {
    "presenton": {
      "url": "http://localhost:5001/mcp",
      "headers": {
        "Authorization": "Bearer <access_token>"
      }
    }
  }
}

Notes:

• If you rotate credentials with AUTH_OVERRIDE_FROM_ENV=true, previously issued session tokens are invalidated.
• MCP is not available in the Electron desktop app (PRESENTON_ELECTRON=true). Electron runs with DISABLE_AUTH=true by default, and the MCP server is disabled there to avoid auth conflicts.

Note: LLM and image variables above are forwarded from docker-compose.yml when set in .env.

Docker Run Examples by Provider

Same variables as compose; use -e instead of .env when running docker run directly.

• Using OpenAI

• Running Presenton with GPU Support
  To use GPU acceleration with Ollama models, you need to install and configure the NVIDIA Container Toolkit. This allows Docker containers to access your NVIDIA GPU.
  Once the NVIDIA Container Toolkit is installed and configured, you can run Presenton with GPU support by adding the --gpus=all flag:

  docker run -it --name presenton --gpus=all -p 5001:80 -e LLM="ollama" -e OLLAMA_MODEL="llama3.2:3b" -e IMAGE_PROVIDER="pexels" -e PEXELS_API_KEY="*******" -e CAN_CHANGE_KEYS="false" -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest

• Using an OpenAI-Compatible Image Provider

  This routes all slide image requests through your OpenAI-compatible gateway (LiteLLM, Azure, vLLM, etc.) while keeping the text LLM configuration independent:

  docker run -it --name presenton -p 5001:80 -e IMAGE_PROVIDER="openai_compatible" -e OPENAI_COMPAT_IMAGE_BASE_URL="https://proxy.example.com/v1" -e OPENAI_COMPAT_IMAGE_API_KEY="******" -e OPENAI_COMPAT_IMAGE_MODEL="gpt-image-1" -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest

✨ Generate Presentation via API

Generate Presentation

Endpoint: /api/v1/ppt/presentation/generate
Method: POST
Content-Type: application/json

Authentication (HTTP Basic):
All /api/v1/ routes except /api/v1/auth/* require authentication. Send your Presenton admin username and password (same as the web UI, or AUTH_USERNAME / AUTH_PASSWORD when preseeding Docker). With curl, put them right after -u as -u USERNAME:PASSWORD — that is HTTP Basic auth and sets Authorization: Basic … for you. Replace the sample username:password below with your real credentials.

Request Body

Response

{
  "presentation_id": "string",
  "path": "string",
  "edit_path": "string"
