Kubernetes provides a number of features that allow users to build robust solutions, such as the ability to automatically restart unhealthy containers. To make the most of these features, K8s needs to be able to accurately determine the status of user applications.This means actively monitoring Container Health. Health Checks are a good way to let the K8s system know if an instance of the application…

Kubernetes (k8s) is an amazing technology and I’m loving it. Kubernetes comes in various forms from vanilla Kubernetes to turnkey solutions like RedHat OpenShift. In fact, you can provision a single-node Kubernetes(k8s) cluster using Minikube on your local machine. In this article, I will show you how we can leverage the Virtual Machines (VM’s) provided by Google Cloud to make a Kubernetes Cluster. We will…

admin 4 days ago in

Kubernetes is a system for managing containerized applications across a cluster of nodes. In simple terms, you have a group of machines and containerized applications (e.g. Dockerized applications), and Kubernetes will help you to easily manage those apps across those machines. It is used as an alternative for the docker swarm. Kubernetes follows a client-server architecture. The master server consists of various components including a…
