In this page, you will find articles that are related to computer infrastructure operations that are performed in the course of software development.

Examples include how to setup the server infrastructure to run Python applications, WordPress applications and etc.

Building a reverse proxy server with Nginx, Certbot, Raspbian Stretch Lite and Raspberry Pi 3

The Nginx reverse proxy server runs well on Raspberry Pi 3 and you can use it behind a router to route HTTP traffic to upstream web applications.

A Raspberry Pi 3 reverse proxy server is a very useful appliance to help us host multiple websites from home.

Some examples of web applications that you may want to host at home includes:

This post discusses how you can build a reverse proxy server with nginx, Certbot, Raspbian Stretch Lite and Raspberry Pi 3 to proxy HTTP traffic directed at applications on your home network.

Understanding the difference between the root and alias directives in Nginx

Nginx is a web server that is good for serving as a reverse proxy server, load balancer or HTTP cache.

One of the most important task in configuring Nginx to proxy HTTP / HTTPS traffic is telling Nginx where to look for files that it needs for serving HTTP / HTTPS requests.

This posts discusses the root and alias directives that we can use in Nginx configuration files for mapping a url from a HTTP request to a file on the server file system.

Installing Certbot on Raspbian Stretch Lite for obtaining Let’s Encrypt’s browser-trusted certificates

By offering free browser-trusted certificates, Let’s Encrypt makes it easy for ordinary folks like you and me to deploy secure web applications that serve HTTPS traffic 24-7.

The issuance of Let’s Encrypt certificates is automated by software participating in the ACME protocol. We will need to run such a software on devices which host web servers serving HTTPS traffic.

The Raspbian Stretch Lite operating system is a way to create performant web-based appliances with Raspberry Pis. If you need to secure your web-based applications on Raspbian Stretch Lite, you may choose to install Certbot on Raspbian Stretch Lite as a first step.

This post extends Certbot’s installation instruction on Debian Stretch to provide the steps for installing Certbot on Raspbian Stretch Lite.

How to setup Raspbian Stretch Lite on Raspberry Pi 3 to run Python 3 applications

Raspbian Stretch Lite operating system is the Raspberry Pi Foundation’s official supported operating system for running headless software. It is a good operating system for different Raspberry Pi 3 use cases. Some examples include:

If you are planning to use Raspberry Pi 3 GPIO to interface with the real world, it is recommended that you setup Raspbian Stretch Lite to run Python 3 applications.

This post provides the steps to setup Raspbian Stretch Lite on Raspberry Pi 3 for running Python 3 applications.

Setting up a fast git server on Raspberry Pi Zero W with Go Git Service (Gogs) and Raspbian Stretch Lite

The Go Programming Language is a compiled programming language created by Robert Griesemer, Rob Pike, and Ken Thompson from Google in 2009. With Google Go, it is possible to build programs that run efficiently on minimum hardware resources. The compiled code runs close to the speed of C. Use cases of Go Programming language includes Docker, Kubernetes and Go Git Service.

If you happen to need a self-hosted git server to track software projects that you build on the side, you can consider using Go Git Service. With the Raspberry Pi Zero W bundle set, you can set up a fast git server that does not take up too much space on your desk.

This post details how you can setup a fast git server on Raspberry Pi Zero W with Go Git Service and Raspbian Stretch Lite.
