Micropython works on a variety of different boards, but originally it was written to work on STM32 microcontrollers. Their PYBOARD is based on STM32.
At the moment micropython is ported to several STM32 developer boards, ESP32, linux, MacOS and even webassembly.
I started porting micropython to STM32F469-Discovery board - I want to
There are many ways to parse in variable into the nginx config file.
Some uses set_by_lua which is offered by lua-nginx-module.
Some use envstubst to populate varilabes into a template file.
Today I am going to show you how to do that with njs the JS scripting engine for nginx.
## /etc/nginx/fetch_env.js
function fetch_upstream_host(r) {
return process.env.UPSTREAM_HOST;
