Hardware Recommendations for Kubernetes Cluster

General Discussions

Hi everyone,

I’m planning to set up a small Kubernetes cluster for testing and learning purposes, and I need advice on the hardware side. My current plan includes using multiple nodes with moderate specs to simulate a real-world environment.

One of the options I’m considering for storage is the SATA 6Gbps SSD/120GB-MU-2.5Inch, primarily for the master node to ensure faster etcd performance and smoother control plane operations. Would this SSD be sufficient for a small cluster, or should I look for something with more capacity or higher IOPS?

Additionally, are there any other specific hardware components (e.g., network interfaces, memory configurations) that I should prioritize for an efficient Kubernetes setup?

Thanks in advance for your insights and recommendations!

Stop overthinking it. Just use Virtaulbox VMs and install your kubeadm cluster, it is how I use K8s. Here is a video for setting up your Virtualbox VMS for kubernetes , https://youtu.be/lOxwwq0LQYo . ANd here’s another video for installing a Kubeadm cluster on your VMs, https://youtu.be/W3337KFn5I0 . Hope it helps
