streamlit-nginx is a Docker image with Streamlit and Nginx for web-based demo applications in Python 3.6 and above, in a single container.

The Docker image is configured using a server upstream in Nginx, which allows the deployment to Kubernetes clusters without the risk to get a socket connection timeout without editing the default values (see discussion here)

Here's the supported tags with the corresponding Dockerfile:

• python3.6
• python3.7
• python3.8
• python3.9
• latest (Only available in Docker Hub, it is an alias for the most recent Python version, 3.9 at the moment)

streamlit-nginx should be used as a base image for the containers hosting your own Streamlit application. You should set the base image in your Dockerfile, without cloning the repository:

FROM lucone83/streamlit-nginx:python3.8

<your Dockerfile code>

CMD ["streamlit", "run", "your_application_file_path.py"]

You can override the default nginx settings file with your own. All you need to do is to copy it in the right container folder. Your Dockerfilewill look like:

FROM lucone83/streamlit-nginx:python3.8

<your Dockerfile code ... >

COPY --chown=streamlitapp your-nginx-file-path /home/streamlitapp/.nginx/nginx.conf

< ... rest of your Dockerfile code>

NOTE: at the moment I haven't introduced the possibility to change the app directory in an easy way. The Docker image has a default user (streamlitapp) with its own home directory (/home/streamlitapp). At the moment it is not possible to change the nginx listening port, which is set to 8080.
