Custom Resource Definitions (CRDs) are Kubernetes API extensions which can define new object types. Pods, ReplicaSets, ConfigMaps, and Ingresses are examples of common built-in resources. CRDs let you add entirely new types to this list, then manage them using familiar Kubernetes tools such as Kubectl. Kubernetes is a dynamic system that automatically adapts to your workload’s resource utilization. Kubernetes has two levels of scaling. Each individual Kubernetes deployment can be scaled automatically using a Horizontal Pod Autoscaler (HPA), while the cluster at large is scaled using Cluster Autoscaler.To get CPU and Memory usage you can use (depending on the object you like to see) the following: kubectl top pods or kubectl top nodes which will show you $ kubectl top pods NAME CPU(cores) MEMORY(bytes) nginx-1-5d4f8f66d9-xmhnh 0m 1Mi The Kubernetes API can be extended using Custom Resources, which represent objects that are not part of the standard Kubernetes installation.

Jan 16, 2024 · Two Kubernetes resources, however, let you manage these types of applications: StatefulSets maintain the state of applications beyond an individual pod lifecycle. DaemonSets ensure a running instance on each node, early in the Kubernetes bootstrap process. StatefulSets. Modern application development often aims for stateless applications. Kubernetes, also known as k8s or kube, is an open source container orchestration platform for scheduling and automating the deployment, management and scaling of containerized applications. Today, Kubernetes and the broader ecosystem of container-related technologies have merged to form the building blocks of modern cloud infrastructure. A Pod resource request/limit for a particular resource type is the sum of the resource requests/limits of that type for each Container in the Pod. Meaning of CPU. Limits and requests for CPU resources are measured in cpu units. One cpu, in Kubernetes, is equivalent to 1 vCPU/Core for cloud providers and 1 hyperthread on bare-metal Intel processors. Kubernetes helps you make sure those containerized applications run where and when you want, and helps them find the resources and tools they need to work.
