I would like to share my tips and tricks so you can also be empowered by just sticking to the terminal on your OS or simply using Git Bash on Windows. What is SSH The SSH protocol (also referred to…

In my last blog I shown you how to upgrade from Raspbian Stretch to Raspbian Buster. As the whole upgrade went smooth it seems there are still some issues with Raspbian Buster. The one which blocked me completely was the ability to run Kodi. Kodi was not able to start due to a GUI error. Therefore I decided to switch back to Raspbian Stretch until Raspbian Buster packages catch up. Prerequisuites Before you start a fresh install make sure you have an ethernet cable at hand, as we will need i…

Letsencrypt is a free automated service which provides you SSL certificates for free. Although the certificates are only valid for 3 months, this shouldn't be a bottleneck as you can fully automate the certificate request and renewal.

In this blogpost I will show you how to use the Letsencrypt Vagrant box (Ubuntu vm) to authorize the certification request for your Az…

In the previous part of this series we had a look on building a bare Debian VM with the bare minimum packages installed to run a web server. In this part we will have a look on how we can improve our packer script with user variables and how to use the file and shell provisioner. User variables Variables can be easily added to the packer script by adding following JSON. Best practice is to put your variables as the first property in your JSON, before your builders. This way you have all the…

Large development teams are often coping with the "It works on my machine" syndrome. One solution to solve these kind of issues is by give each single developer the same VM, which is most preferably the same as your production server. So imagine your company is building a web application. The web application is hosted on a Debian server using Apache, MySQL and PHP. So considering these preconditions I will give you a simple example to get your machines scripted and fully provisioned. In this fir…
