Too Long; Didn't Read
This is the second installment of my 'How I built' trilogy detailing the build process of all 3 of my clusters. The Kraken cluster was built out of 7 Raspberry Pi 3Bs powered by a single USB charger. The total damage my wallet sustained from Kraken was S$626.63 or in $449.73 USD, which was virtually all I had left for the month after subtracting expenses and education loan repayments. I chose a 32GB MicroSD card as storage for the first node as I had intended it to be the main node of a Docker swarm setup.
