Kubernetes resources

Overview. Kubernetes is a portable, extensible, open source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.

Changing built-in resources. When you extend the Kubernetes API by adding custom resources, the added resources always fall into a new API Groups. You cannot replace or change existing API groups. Adding an API does not directly let you affect the behavior of existing APIs (such as Pods), whereas API Access Extensions do.

kubernetes_cron_job. A Cron Job creates Jobs on a time-based schedule. One CronJob object is like one line of a crontab (cron table) file. It runs a job periodically on a given schedule, written in Cron format. Note: All CronJob schedule times are based on the timezone of the master where the job is initiated.Job is a Kubernetes resource that runs a Pod, or perhaps several Pods, to carry out a task and then stop.

Jan 7, 2024 · Different Kubernetes resource types. At the time of writing this tutorial, there were there different resource types for which requests and limits could be imposed on a Pod and Container: CPU; Memory; Hugepages (Kubernetes v1.14 or newer) CPU and memory are collectively referred to as compute resources, or just resources. Nov 26, 2021 · Kubernetes v1.22, released in August 2021, introduced a new alpha feature that improves how Linux nodes implement memory resource requests and limits. In prior releases, Kubernetes did not support memory quality guarantees. For example, if you set container resources as follows: apiVersion: v1. kind: Pod. metadata: name: example.Feb 16, 2024 · In Kubernetes, scheduling refers to making sure that Pods are matched to Nodes so that Kubelet can run them.

In Kubernetes, a HorizontalPodAutoscaler automatically updates a workload resource (such as a Deployment or StatefulSet), with the aim of automatically scaling the workload to match demand. Horizontal scaling means that the response to increased load is to deploy more Pods.

Ownership is different from the labels and selectors mechanism that some resources also use. For example, consider a Service that creates EndpointSlice objects. …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.
