To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'. kubectl cluster-info [flags] Examples # Print the address of the control plane and cluster services kubectl cluster-info Options -h, --help help for cluster-info --as string Username to impersonate for the operation. User could be a regular user or a service account in a namespace. --as-group strings Group to impersonate for the operation, this flag can be repeated to specify multiple groups.

In v1.15.0, kubeadm introduced preliminary support for kubeadm upgrade node phases. Phases for other kubeadm upgrade sub-commands such as apply, could be added in the following releases. kubeadm upgrade node phase Using this phase you can choose to execute the separate steps of the upgrade of secondary control-plane or worker nodes. Please note that kubeadm upgrade apply still has to be called on a primary control-plane node. phase preflight control-plane kubelet-config Use this command to invoke single phase of the node workflow

Synopsis Dump cluster information out suitable for debugging and diagnosing cluster problems. By default, dumps everything to stdout. You can optionally specify a directory with --output-directory. If you specify a directory, Kubernetes will build a set of files in that directory. By default, only dumps things in the current namespace and 'kube-system' namespace, but you can switch to a different namespace with the --namespaces flag, or specify --all-namespaces to dump all namespaces.

Seccomp stands for secure computing mode and has been a feature of the Linux kernel since version 2.6.12. It can be used to sandbox the privileges of a process, restricting the calls it is able to make from userspace into the kernel. Kubernetes lets you automatically apply seccomp profiles loaded onto a node to your Pods and containers. Seccomp fields FEATURE STATE: Kubernetes v1.19 [stable] There are four ways to specify a seccomp profile for a pod:

Bootstrap tokens are used for establishing bidirectional trust between a node joining the cluster and a control-plane node, as described in authenticating with bootstrap tokens. kubeadm init creates an initial token with a 24-hour TTL. The following commands allow you to manage such a token and also to create and manage new ones. kubeadm token create Create bootstrap tokens on the server Synopsis This command will create a bootstrap token for you.
