Q
How to expose the web ui of the netFIELD Apps securely on hosts that are not running netFIELD OS?
A
When using the app on hosts that are not running Hilscher's "netFIELD OS" operating system it is up to the end-user to implement an appropriate mechanism to expose the app's web ui port in a secure way.
The most effective and easy solution is to use an nginx reverse proxy container as the secure bridge between the internal container network and the hosts external network
Nginx is able to offer a broad range of security controls that most likely match nearly all end-user needs: https://docs.nginx.com/nginx/admin-guide/security-controls/
The overall setup then may look like the following illustration shows.
