How to add environment variables to nginx.conf

This is the hack approach to adding environment variables to the nginx configuration files. As with most Google results for this search, the reason is Docker.

The setup

I intended to deploy two Docker containers.

Nginx FastCGI response buffer sizes

By default when Nginx starts receiving a response from a FastCGI backend (such as PHP-FPM) it will buffer the response in memory before delivering it to the client. Any response larger than the set buffer size is saved to a temporary file on disk.

This process is outlined at the Nginx ngx_http_fastcgi_module page manual page.

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

	import PropTypes from 'prop-types';

	type Omit<T, K> = Pick<T, Exclude<keyof T, K>>;

	type Defined<T> = T extends undefined ? never : T;

	/**
	* Get the type that represents the props with the defaultProps included.
	*
	* Alternatively, we could have done something like this:

	import { withRouter } from 'next/router';
	import Link from 'next/link';
	import React, { Children } from 'react';

	const ActiveLink = ({ router, children, ...props }) => {
	const child = Children.only(children);

	let className = child.props.className \|\| '';
	if (router.pathname === props.href && props.activeClassName) {
	className = `${className} ${props.activeClassName}`.trim();

	/**
	* VueRouteData plugin for [email protected] and vue@1or2,
	* implemented according to https://github.com/vuejs/vue-router/issues/296#issuecomment-235481643
	*
	* This plugin looks for `$options.fetchRouteData`,
	* and watches `$route` using `$options.fetchRouteData` as handler.
	*
	* Before `fetchRouteData` executes, this plugin sets 'loadingRouteData' to true,
	* and when it finishes executing, the plugin sets 'loadingRouteData' to false,
	* so `fetchRouteData` can either be normal functions or async functions.
