The last post on this blog was about Jib, Google’s daemonless Java image builder. That was July 2018. Almost eight years ago. Anybody remember when that was the latest hotness?
Before that, I wrote about Docker when Docker was still exciting and built a Kubernetes cluster on Raspberry Pi 3 nodes when that was still a weekend adventure. I spent way too many words on Jolokia and JMX. 27 posts between 2010 and 2018, then silence. If you’ve been reading tech blogs long enough, you know how that goes.
So what breaks eight years of silence?
Octobox is for sure one of my favourite tools in my GitHub centred developer workflow. It is incredible for GitHub notification management which allows me to ignore all the hundreds of GitHub notification emails I get daily.
Octobox is a Ruby-on-Rails application and can be used as SaaS at octobox.io or installed and used separately. Running Octobox in an own account is especially appealing for privacy reasons and for advanced features which are not enabled in the hosted version (like periodic background fetching or more information per notification).
This post shows how Octobox can be ported to the free “starter” tier of OpenShift Online.
Our Ansible Playbooks for installing Kubernetes on a Raspberry Pi Cluster have been constantly updated and are now using the awesome kubeadm. The update to Kubernetes 1.6. was a bit tricky, though.
Let’s build a Raspberry Pi Cluster running Docker and Kubernetes. There has been already a handful of good recipes, however this howto is a bit different and provides some unique features.
