Unofficial bash strict mode

Unofficial Bash Strict Mode

Sometimes a programming language has a "strict mode" to restrict unsafe constructs. E.g., Perl has use strict, Javascript has "use strict", and Visual Basic has Option Strict. But what about bash? Well, bash doesn't have a strict mode as such, but it does have an unofficial strict mode:

set -euo pipefail

set -e

Raspberry Pi, Static HTTPS site with Docker and Nginx

Raspberry Pi, Static HTTPS site with Docker and Nginx

This tutorial is dated Oct 2021, if it's much further on than that this information might be out of date.

This is a guide on setting up a static HTTPS website on your raspberry pi using docker and nginx. The aim is to have this running on the raspberry pi and to be able to access it from a host computer on the same local network. You should already be able to ssh into your pi from your host computer and have raspberry pi OS set up.

Find your raspberry pi
