A while back, I started using a Raspberry Pi 4B with 2GB of RAM as my home router.
The reason for doing this is because my ISP modem is pretty basic and limited. I also didn’t want to have to reconfigure my network each time I changed modem or ISP.
Some benefits I got from using the RPI4 as a router were that I could setup an ad blocker, Pi-hole in my case, as well as adding a small UPS, for power outages, and LTE modem, for ISP outages (I haven’t configured this last one).
After using my PiRouter (that’s what I like calling it) for a while, I decided to clean everything up and standarize it, so that I could replicate it if/when I had to replace my Raspberry or the microSD card, as painlessly as possible.
In these series of articles I’ll be detailing how I configured it using Git, Docker and Ansible, having learned the basics of Ansible from the great guides published by Jeff Geerling.
