kubernetes (Page 3)

In the last three parts we covered, starting from scratch and getting the Kubernetes platform ready, this was using some old hardware and creating some virtual machines to act as my nodes. But if you don’t have old hardware but you still wish to build out your cluster then these virtual machines can really sit wherever they need to, for example, they could be in the public cloud but remember this is going to cost you. My intention was to remove all costs as possible as this system I am using is always running in my home network as it acts as my backup serverRead More →

In the last post, we went through creating our home lab Kubernetes cluster and deploying the Kubernetes dashboard. In this post we are going to create a couple more stateless applications. What is BusyBox Several stripped-down Unix tools in a single executable file. Commonly referred to as the “Swiss army knife tool in Linux distributions” I began by just testing this following a walkthrough tutorial but then later realised that this is a great tool for troubleshooting within your Kubernetes pod. You can find out more information here on Docker Hub. kubectl run myshell –rm -it –image busybox – sh Some things you didn’t knowRead More →

In the last post, we walked through the pretty basic way of getting our physical and virtual environment ready for our Kubernetes cluster. This post will cover the Kubernetes cluster setup steps. Kubernetes Cluster At this stage, we just have 3 virtual machines running Ubuntu on a flat layer 2 network. Now things get a little more interesting, in one of the last steps of part 1 we touched on installing kubeadm and this is where I am going to focus my installation and configuration, however, you can use the more challenging approach and build out from scratch.
