KOTS: passing HTTP_PROXY environment variables to my application containers

What is the suggested way to pass HTTP_PROXY environment variables from the installation to my application containers?

What about NO_PROXY?

These have to be set manually for the application. We provide template functions, which read these values from kotsadm pod environment: Static Context - Kots.io

If kots isinstalled without proxy info, then application will need to have config options that can be set in Admin Console.
