Quite an old thread, but I would like to leave my solution to make Streamlit working on a Docker container on a Synology NAS.
Things to do:
- Register a DynDNS on your domain register
- Enable the DynDNS at Synology > Control Panel > External Access > DDNS > …
- Create a domain certificate, for example, at Let’s Encrypt, going to: Synology > Control Panel > Security > Certificate > Add…
- Set the certificate for your DynDNS domain, at: Synology > Control Panel > Security > Certificate > Settings …
- Enable firewall for the Docker container, at Synology > Control Panel > Security > Firewall > Edit Rules > Create > …
- Setup the reverse proxy, at: Synology > Control Panel > Login Portal > Advanced > Reverse Proxy > …
- You can enable HSTS if you want at the Reverse Proxy
- Enable the websocket at: Synology > Control Panel > Login Portal > Advanced > Reverse Proxy > Custom Header > Create > WebSocket > …
- Setup the Docker container at the “Container Manager” app inside Synology. You can use the
docker-compose.yml, and create a “Project”.
As example, these are my files:
Dockerfile
# app/Dockerfile
FROM python:3.12-slim
WORKDIR /app
RUN apt-get update && apt-get install -y \
build-essential \
curl \
software-properties-common \
&& rm -rf /var/lib/apt/lists/*
COPY requirements.txt .
RUN pip install -r requirements.txt
VOLUME ["/app"]
EXPOSE 8501
HEALTHCHECK CMD curl --fail http://localhost:8501/_stcore/health
ENTRYPOINT ["streamlit", "run", "main.py", "--server.port=8501", "--server. Address=0.0.0.0"]
docker-compose.yml
version: '3.8'
services:
streamlit_app:

dockerfile: Dockerfile
container_name: app
hostname: app
ports:
