Recently I have been using a Raspberry Pi 3B+ bought from a classified advertisement site called Bikroy.com. A student wanted to sell this, as his final college project was done. It was cheaper with an acrylic casing and a fan. However, I wanted to use this Pi for several pet projects. Initially I did install Pi-Hole for network wide adblocker and along with samba with a spare portable hard disk. It was working OK. No extra pressure in this 1GB ram Pi. I thought Why not give it a little bit more pressure?

Thus, I planned to install docker registry in it for my “local private docker hub” type of need. Let me share what I had to do.
