K3s

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. root@k3s-master-1:/var/lib/rancher/k3s/server/manifests# cat traefik.yaml apiVersion: helm.cattle.io/v1 kind: HelmChart metadata: name: traefik namespace: kube-system spec: chart: https://%{KUBERNETES_API}%/static/charts/traefik-1.77.1.tgz set: rbac.enabled: "true" ssl.enabled: "true" metrics.prometheus.enabled: "true" kubernetes.ingressEndpoint.useDefaultPublishedService: "true" dashboard.enabled: "true" root@k3s-master-1:/var/lib/rancher/k3s/server/manifests# cat traefik.yaml apiVersion: helm.cattle.io/v1 kind: HelmChart metadata: name: traefik namespace: kube-system spec: chart: https://%{KUBERNETES_API}%/static/charts/traefik-1.77.1.tgz set: rbac.enabled: "true" ssl.enabled: "true" metrics.prometheus.enabled: "true" kubernetes.ingressEndpoint.useDefaultPublishedService: "true" dashboard.enabled: "true" After a few minutes you will see some extra pods getting started. ...

In my post about first experience with k3s I blogged about setting up my k3s based cluster on Raspberry PI’s. Since that post I have added two more nodes Raspberry Pi’s and also updated to the 0.3.0 version of k3s. pi@k3s-master-1:~ $ kubectl get nodes NAME STATUS ROLES AGE VERSION k3s-master-1 Ready master 4h11m v1.13.5-k3s.1 k3s-node-1 Ready node 129m v1.13.5-k3s.1 k3s-node-2 Ready node 118m v1.13.5-k3s.1 k3s-node-3 Ready node 119m v1.13.5-k3s.1 pi@k3s-master-1:~ $ Next step for me was getting the Kubernetes Dashboard up and running. I used the information from Web UI (Dashboard) First downloaded I the kubernetes-dashboard.yaml ...

Rancher has released v0.2.0.of k3s. Information of the new release is in this article. As soon as I have some time and I have added two extra nodes to the cluster, I’m going to add the cluster to my Rancher server. I have upgraded my Raspberry Pi’s to v0.2.0. The process of upgrading is really simple. Just download the new version and replace the old version of k3s with the new version and restart. ...

Rancher introduced alsmost week ago k3s, a lightweight Kubernetes Distribution. In the YouTube video below you hear Shannon Williams and Darren Shepherd from Rancher talk about K3S, what it is, the usecases and demo of K3S. https://youtu.be/5-5t672vFi4 k3sis a fully compliant, production-grade Kubernetes distribution that maintains an absolutely tiny footprint. Weighing in at less than 40 MB, it only needs 512 MB of RAM to run. This means it’s perfect for all kinds of computing that requires a minimal about of memory and space. ...
