In this blog entry I would like to explain how to write an annotation processor. First, I am going to explain to you what annotation processing is, what you can do with that powerful tool and finally what you cannot do with it.

Kubernetes Traffic Engineering with BGP July 23, 2018 Turns out you can use good old BGP to power your Kubernetes network! In this post I’ll cover how to build your Kubernetes network with BGP and how to use it for traffic engineering in your Kubernetes clusters! My hope is that this post gives yo

The snmp_exporter is one of the trickier Prometheus components to set up because there’s a few moving parts involved in a full configuration and because of the need to run an extra tool to generate the snmp.yml config file from the ever-mysterious “MIBS”.

What is k3d?¶ k3d is a lightweight wrapper to run k3s (Rancher Lab’s minimal Kubernetes distribution) in docker. k3d makes it very easy to create single- and multi-node k3s clusters in docker, e.g. for local development on Kubernetes.

K3s is a highly available, certified Kubernetes distribution designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances.

Besides the criticism of Serverless computing [1], it is quite popular these days especially the AWS lambda functions. In this blog, we will deploy OpenWhisk one of the popular opensource serverless computing platforms along with Kubernetes to create a serverless computing environment.

Sealed types, switch expressions, and record types. Here are just a few new features introduced in the latest Groovy 4.0 release. In this video, I want to show you ten things that make Groovy 4.0 amazing. And to keep this video short, we’re not going to dive deep into each of them.
