Configure Streamlit to listen on all network interfaces (0.0.0.0)

[t0mdavid-m]

Summary

This PR updates the Streamlit configuration to bind to all network interfaces (0.0.0.0) instead of the default localhost-only binding. This allows the application to be accessible from external hosts when deployed in containerized environments.

Changes Made

• .streamlit/config.toml: Added address = "0.0.0.0" to the [server] configuration section
• Dockerfile: Updated the single-instance entrypoint to explicitly pass --server.address 0.0.0.0 flag when starting Streamlit
• Dockerfile_simple:
  • Updated the nginx configuration to listen on 0.0.0.0:8501 (changed from 8501)
  • Updated the single-instance entrypoint to explicitly pass --server.address 0.0.0.0 flag when starting Streamlit

Implementation Details

The changes ensure consistent network binding across all deployment scenarios:

• The config file provides a default binding for local development
• The Docker entrypoint flags override/reinforce this setting for containerized deployments
• The nginx configuration in multi-instance mode now explicitly binds to all interfaces, making it accessible from outside the container
• Both single-instance and multi-instance deployment modes are updated for consistency
