Introduction to Logging and Monitoring Logging and Monitoring of Kubernetes cluster components and containerized applications is crucial to debugging and lifecycle management. Where a basic difference between the two is – Monitoring involves the consistent examination of components to gain an understanding of their health status. Logging involves the recording of cluster events so that…
Introduction to Scheduling in Kubernetes In Kubernetes clusters, Schedulers are the control plane elements that ensure pods are assigned to the right nodes where they will run on the Kubelet service.
