streamlit-nginx

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.

Description

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)

Supported tags

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)

How to use

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"]

Advanced use

Custom nginx settings

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.
