Kubernetes

If you have seen errors like these when deploying using a serviceAccount

Looking the official diagram from devspace which shows the benefits in detail

So there are many things I have been simultaneously trying to learn & one of those is to learn how you can configure a pipeline

While I continue to learn more about architecture and design of kafka, a quickstart to deploy & test kafka is a must. Step 1: Add Chart Repo # In my local system it is already present which was confirmed by the listing

I have written a series of blogs to capture how you can deploy spinnaker on a Kubernetes cluster & manage a helm chart deployment via pipeline.

Deploying Jenkins on K8S cluster is as simple as

In this blog, I will try add a new node to the already running cluster. My Cluster # root@master>k get nodes NAME STATUS ROLES AGE VERSION mydevmachine001830.samarthya.me Ready <none> 22h v1.23.1 mydevmachine002687.samarthya.me Ready <none> 41d v1.23.1 mydevmachine003277.samarthya.me Ready <none> 131d v1.23.1 mydevmachine003278.samarthya.me Ready <none> 131d v1.23.1 mydevmachine003417.samarthya.me Ready <none> 4m55s v1.23.1 mydevmachine003968.samarthya.me Ready <none> 131d v1.23.1 mydevmachine003969.samarthya.me Ready control-plane,master 131d v1.23.1 mydevmachine003970.samarthya.me Ready <none> 131d v1.23.1 mydevmachine003979.samarthya.me Ready <none> 29m v1.23.1 Steps to follow # Install docker Install kubeadm, kubectl & kubelet Join the cluster using the token Check the node has joined the cluster Step 1: Install docker # sudo yum install -y yum-utils sudo yum-config-manager \ --add-repo \ https://download.docker.com/linux/centos/docker-ce.repo When adding repo make sure the repo has been added successfully to the machine

In this blog I will talk about how you can upgrade a node and the kubernetes cluster version to a specific version. I have a 6 node local Kubernetes cluster like below

What? # Role Based Access Control(s) is a way of regulating access to entities like storage, network etc. RBAC authorization uses rbac.authorization.k8s.io API group. API Objects # There are 4 kind of kubernetes object

In my cluster things went haywire all of a sudden without a proper showcase, I tried multiple things but it was just not working. Specifically my core-dns and calico-kube-controllers were not coming up and were constantly showing not ready and CrashLoop respectively
