Moving to Docker container series blog post, I choose to continue with Kubernetes and discuss it more start with configuration and installation.
This configuration discuss on-premise side and to do that you have at least 2 servers
node which controls and manages a set of worker nodes (workloads runtime) and resembles a cluster in Kubernetes. A master node has the following components to help manage worker nodes: … Kube-Controller-Manager, which runs a set of controllers for the running cluster.
The worker node
A Node is a worker machine in Kubernetes and may be either a virtual or a physical machine, depending on the cluster. … Each Node is managed by the Master. A Node can have multiple pods, and the Kubernetes master automatically handles scheduling the pods across the Nodes in the cluster.
Configure The Kubernetes cluster
On all nodes, add the Kubernetes repo to /etc/yum.repos.d:
cat <<EOF | sudo tee /etc/yum.repos.d/kubernetes.repo
Copy the kubeadm join command, then paste and run it in your worker nodes terminal windows.
From the worker nodes, verify that they can see the cluster
docker ps -a
From Node 1 (Master), check the status of the nodes
kubectl get nodes
Now, Kubernetes installed but it’s empty to have pods or services the next will be for you, it can be change depends on your application type but it’s Just for testing to show the reader how it’s goes.
