I spent all day debugging an issue with OpenShift. Learned a bit about InitContainers and debugging them and realized how I need to learn to use the tool before using it instead of blindly shooting in the air.

Today I practiced with replicasets, deployments and namespaces. While reading about the difference between RS and Deployments, I came across this good article — https://medium.com/stakater/k8s-deployments-vs-statefulsets-vs-daemonsets-60582f0c62d4

So, it’s been 5 days since my last post. I have been lazy with this challenge. Well, this time it wasn’t for the laziness reasons that I had this big break, there were a lot of other things going. Anyway, today I dealt with OpenShift clusters and deployments. I have…

I played a bit with labels and kubectl today.

So, today I practiced some troubleshooting related to services and pods.

Still on setting up the cluster with kubeadm!

I came down with food poisoning and had to take 2 days off. Anyway, I’m better today and back at it! Today I am attempting at setting up a local cluster with kubeadm tool. The nodes will be deployed as Vagrant VMs and then I’ll be setting up with kubeadm.
