Certified Rancher Operator

Last week I completed Certified Rancher Operator: Level 1. I already had some experience with the products of Rancher Labs. I wrote some posts about the K3S product and I have implemented a Rancher based solution at a customer. Next to that I was part of team tht build a Rancher based platform to host different teams in a muli tenant setup. I already heard that Rancher was thinking about certifications for their products.

Blog updated and migrated

In 2015 I started with a personal blog which was called Mindmelt.nl. This blog was based on Wordpress and up until now my blog was running there.Last year I talked with some colleagues about which platform they were using and some of them mentioned Hugo. I really like Hugo and also the fact that when you can check your post local before publishing, push it to a git repository and have it automatically being hosted online.

Fling: Kubewise

The engineers from VMware created a new cool fling, Kubewise. If you want to get in contact with the engineers who created it or download it, go to https://flings.vmware.com/kubewise. You can run this tool on Microsoft Windows, Linux, or Apple Macbook. Summary Kubewise is a simple multi-platform desktop client for Kubernetes®. In the same way the kubectl command requires only a valid kubeconfig file to run commands against a Kubernetes cluster, Kubewise requires you just to configure one or more valid kubeconfig files to interact with the corresponding Kubernetes clusters.

k3s: Enable Traefik dashboard

If you install k3s with the default settings it also installs Traefik as a load balancer. Traefik also offers a dashboard which is very easy to enable. If you go on your k3s machines to the path /var/lib/rancher/k3s/server/manifests you can find their traefik.yaml. To enable the Traefik dashboard you have to add dashboard.enabled: “true” to the yaml. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 root@k3s-master-1:/var/lib/rancher/k3s/server/manifests# cat traefik.

Google Certified Associate Cloud Engineer

Today I got the email from Google saying that I passed the Google Cloud Associate Engineer certification. Last Friday I took the exam at a Kryterion test center and got the pass score but had to wait till the final approval from Google. At my current job I don’t work with Google Cloud but more with Microsoft Azure, AWS and data center environments. Google certification was on my list of certifications I wanted to look into.

Rebuilding my homelab

A month or so ago I started with building a homelab for running Kubernetes. I choose Raspberry Pi’s to run my workloads on. I started with the use of kubeadm to deploy Kubernetes and chose the blog of Alex Ellis as my starting point. I ran into some problems in my attempts to get it working but finally I succeeded to get it working. Soon after that Rancher Labs, released K3S which was targeted at edge and iot solutions and perfect for running on Raspberry Pi’s.
