Kubernetes upgrade – kubeadm

kubeadm is still in beta, but if you already deployed a Kubernetes cluster on some environment using it and now want to upgrade, you can do that manually. In some of previous posts, I wrote about Kubernetes deployment with kubeadm and it is available here https://crondev.com/kubernetes-installation-kubeadm. Currently kubeadm does not have support for cluster upgrade. This is a proposal I found, so it should be available later https://github.com/kubernetes/kubeadm/issues/14.

Kubernetes installation with kubeadm

In my previous post, I presented an easy way how to deploy Kubernetes cluster with Rancher. Kubernetes is hard to install without using third party tools, but luckily they released an official tool for simple deployment kubeadm. Please note that kubeadm is still in Alpha and not ready for production use, but it is good enough to play with on development environments. Kubernetes installation with kubeadm really simplifies deployment procedure and it is easy to use. Also, I find it very stable during my testing. kubeadm is a part of Kubernetes distribution starting with 1.4.0 release, but it does not track same release process at the moment. I’m expecting it to be ready for Kubernetes 1.6.
