The final Kubernetes distribution to look at is called kops, a CLI tool for configuring, setup and maintaining a Kubernetes cluster inside cloud environments. At the time of writing, only amazon AWS is fully supported, and this will be the focus of this article. With kops, you ultimately define all…

Kubeadm is a CLI tool with the explicit goal to bootstrap a minimum viable, Kubernetes specification conformant cluster. It expects nodes to be preconfigured, and upon using the CLI, it will install the Kubernetes components, create tokens, and join nodes together into a cluster. The documentation page explicitly states that…

Kubespray is a meta distribution with an impressive configurability and scalability. It can be used for various infrastructure types, on-premise or cloud, bare metal or VMs, and it provides fine-grained control about all aspects of the installation process. Also, a wide range and customizability for the control plane storage, CRI…

K3S is a lightweight Kubernetes distribution packed into one single binary. This binary provides a comfortable CLI to manage all aspects of the cluster: Create nodes, join nodes, rotate secrets, and even upgrading. This blog post contains a concise overview about the K3S distribution, and its installation and configuration options. …

Kubernetes is the leading platform for running self-healing containerized applications with fine-granular configuration, access, and security settings. Working with a managed Kubernetes distribution practically for more than 2 years, I decided to prepare for the various certifications to facilitate my learning. What could be a better approach than to start…

Your IOT home network consist of different sensor that provide data about the environment related to different aspects, such as temperature and humidity in the air, the current level of your heater, or other binary data. And interesting and versatile extension are motion sensors. When properly calibrated, meaning that they…

A complete IOT stack running on a Raspberry Pi is an effective way to integrated different sensors for home automation. In the last articles, we learned how to manually add a temperature/humidity sensor to the home network. By using PlatformIO, we manually flash the sensor, then choose available library for…
