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.
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.
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.
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.
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.
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.
