Yesterday a computer, which I had ordered quite a while ago, finally arrived. It is an Intel NUC 10i7FNH with 64GB of memory and a 500GB Samsung 970 EVO Plus. I now have three of these. All the same specs.
I bought them over a period of several months. The 10i7FNH is not the most current model, still the price of every machine I bought was higher than the previous one. Between the first and the last machine there is a price difference of 160 euros. Quite a difference if you take into account the first one cost 790 euros. It is just another effect of COVID-19. Let us hope we can leave this whole pandemic behind us soon.
The Kubernetes cluster now has 144GB of RAM to run applications in. There are three master nodes for High Availability and three master nodes also means etcd has reached quorum.
Adding another master and worker node to a running Kubernetes cluster is quite a job. I could not have done it without the help from this article.
Now I can safely wait for one of the SSDs to break. Master nodes write so much data to disk, it’s just a matter of time before one of the consumer SSDs in the nodes breaks. Or at least that is my expectation. We will see.
