This tutorial shows you how to run a standalone kubelet instance. You may have different motivations for running a standalone kubelet. This tutorial is aimed at introducing you to Kubernetes, even if you don't have much experience with it. You can follow this tutorial and learn about node setup, basic (static) Pods, and how Kubernetes manages containers. Once you have followed this tutorial, you could try using a cluster that has a control plane to manage pods and nodes, and other types of objects.

Objectives Learn what a Kubernetes cluster is. Learn what Minikube is. Start a Kubernetes cluster on your computer. Kubernetes Clusters Kubernetes is a production-grade, open-source platform that orchestrates the placement (scheduling) and execution of application containers within and across computer clusters. Kubernetes coordinates a highly available cluster of computers that are connected to work as a single unit. The abstractions in Kubernetes allow you to deploy containerized applications to a cluster without tying them specifically to individual machines.

What's Kompose? It's a conversion tool for all things compose (namely Docker Compose) to container orchestrators (Kubernetes or OpenShift). More information can be found on the Kompose website at https://kompose.io/. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts.

This page shows how to configure process namespace sharing for a pod. When process namespace sharing is enabled, processes in a container are visible to all other containers in the same pod. You can use this feature to configure cooperating containers, such as a log handler sidecar container, or to troubleshoot container images that don't include debugging utilities like a shell. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster.

This task demonstrates running multiple Jobs based on a common template. You can use this approach to process batches of work in parallel. For this example there are only three items: apple, banana, and cherry. The sample Jobs process each item by printing a string then pausing. See using Jobs in real workloads to learn about how this pattern fits more realistic use cases. Before you begin You should be familiar with the basic, non-parallel, use of Job.

Specify configuration and other data for the Pods that run your workload.

In addition to compiled-in admission plugins, admission plugins can be developed as extensions and run as webhooks configured at runtime. This page describes how to build, configure, use, and monitor admission webhooks. What are admission webhooks? Admission webhooks are HTTP callbacks that receive admission requests and do something with them. You can define two types of admission webhooks, validating admission webhook and mutating admission webhook. Mutating admission webhooks are invoked first, and can modify objects sent to the API server to enforce custom defaults.

This page serves as a reference for the audit annotations of the kubernetes.io namespace. These annotations apply to Event object from API group audit.k8s.io. Note:The following annotations are not used within the Kubernetes API. When you enable auditing in your cluster, audit event data is written using Event from API group audit.k8s.io. The annotations apply to audit events. Audit events are different from objects in the Event API (API group events.

This command initializes a new Kubernetes node and joins it to the existing cluster. Run this on any machine you wish to join an existing cluster Synopsis When joining a kubeadm initialized cluster, we need to establish bidirectional trust. This is split into discovery (having the Node trust the Kubernetes Control Plane) and TLS bootstrap (having the Kubernetes Control Plane trust the Node). There are 2 main schemes for discovery.

Synopsis Set a cluster entry in kubeconfig. Specifying a name that already exists will merge new fields on top of existing values for those fields. kubectl config set-cluster NAME [--server=server] [--certificate-authority=path/to/certificate/authority] [--insecure-skip-tls-verify=true] [--tls-server-name=example.com] Examples # Set only the server field on the e2e cluster entry without touching other values kubectl config set-cluster e2e --server=https://1.2.3.4 # Embed certificate authority data for the e2e cluster entry kubectl config set-cluster e2e --embed-certs --certificate-authority=~/.
