Creating Secret objects using resource configuration file.

This page shows how to debug a node running on the Kubernetes cluster using kubectl debug command. 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. If you do not already have a cluster, you can create one by using minikube or you can use one of these Kubernetes playgrounds:

Mechanisms for accessing metrics at node, volume, pod and container level, as seen by the kubelet.

This page provides details of version compatibility between the Kubernetes device plugin API, and different versions of Kubernetes itself. Compatibility matrix v1alpha1 v1beta1 Kubernetes 1.21 - ✓ Kubernetes 1.22 - ✓ Kubernetes 1.23 - ✓ Kubernetes 1.24 - ✓ Kubernetes 1.25 - ✓ Kubernetes 1.26 - ✓ Key: ✓ Exactly the same features / API objects in both device plugin API and the Kubernetes version. + The device plugin API has features or API objects that may not be present in the Kubernetes cluster, either because the device plugin API has added additional new API calls, or that the server has removed an old API call.

This page contains a list of commonly used kubectl commands and flags. Note:These instructions are for Kubernetes v1.34. To check the version, use the kubectl version command. Kubectl autocomplete BASH source <(kubectl completion bash) # set up autocomplete in bash into the current shell, bash-completion package should be installed first. echo "source <(kubectl completion bash)" >> ~/.bashrc # add autocomplete permanently to your bash shell. You can also use a shorthand alias for kubectl that also works with completion:

kubeadm kubeconfig provides utilities for managing kubeconfig files. For examples on how to use kubeadm kubeconfig user see Generating kubeconfig files for additional users. kubeadm kubeconfig overview Synopsis Kubeconfig file utilities. Options -h, --help help for kubeconfig Options inherited from parent commands --rootfs string The path to the 'real' host root filesystem. This will cause kubeadm to chroot into the provided path. kubeadm kubeconfig user This command can be used to output a kubeconfig file for an additional user.

Synopsis Unset an individual value in a kubeconfig file. PROPERTY_NAME is a dot delimited name where each token represents either an attribute name or a map key. Map keys may not contain dots. kubectl config unset PROPERTY_NAME Examples # Unset the current-context kubectl config unset current-context # Unset namespace in foo context kubectl config unset contexts.foo.namespace Options -h, --help help for unset Parent Options Inherited --as string Username to impersonate for the operation.

During kubeadm init, kubeadm uploads the ClusterConfiguration object to your cluster in a ConfigMap called kubeadm-config in the kube-system namespace. This configuration is then read during kubeadm join, kubeadm reset and kubeadm upgrade. You can use kubeadm config print to print the default static configuration that kubeadm uses for kubeadm init and kubeadm join. Note:The output of the command is meant to serve as an example. You must manually edit the output of this command to adapt to your setup.
