kubeadm join phase enables you to invoke atomic steps of the join process. Hence, you can let kubeadm do some of the work and you can fill in the gaps if you wish to apply customization. kubeadm join phase is consistent with the kubeadm join workflow, and behind the scene both use the same code. kubeadm join phase phase Synopsis Use this command to invoke single phase of the "join" workflow

The status of a node in Kubernetes is a critical aspect of managing a Kubernetes cluster. In this article, we'll cover the basics of monitoring and maintaining node status to ensure a healthy and stable cluster. Node status fields A Node's status contains the following information: Addresses Conditions Capacity and Allocatable Info Declared Features You can use kubectl to view a Node's status and other details: kubectl describe node <insert-node-name-here> Each section of the output is described below.

Synopsis Mark the provided resource as paused. Paused resources will not be reconciled by a controller. Use "kubectl rollout resume" to resume a paused resource. Currently only deployments support being paused. kubectl rollout pause RESOURCE Examples # Mark the nginx deployment as paused # Any current state of the deployment will continue its function; new updates # to the deployment will not have an effect as long as the deployment is paused kubectl rollout pause deployment/nginx Options --allow-missing-template-keys     Default: true If true, ignore any errors in templates when a field or map key is missing in the template.

You can use the Kubernetes command line tool kubectl to interact with the API Server. Using kubectl is straightforward if you are familiar with the Docker command line tool. However, there are a few differences between the Docker commands and the kubectl commands. The following sections show a Docker sub-command and describe the equivalent kubectl command. docker run To run an nginx Deployment and expose the Deployment, see kubectl create deployment.

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=~/.

To allow Kubernetes workloads to use swap, on a Linux node, you must disable the kubelet's default behavior of failing when swap is detected, and specify memory-swap behavior as LimitedSwap: The available choices for swap behavior are: NoSwap (default) Workloads running as Pods on this node do not and cannot use swap. However, processes outside of Kubernetes' scope, such as system daemons (including the kubelet itself!) can utilize swap. This behavior is beneficial for protecting the node from system-level memory spikes, but it does not safeguard the workloads themselves from such spikes.
