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:

Creating Secret objects using kubectl command line.

This guide shows you how to create, edit and share diagrams using the Mermaid JavaScript library. Mermaid.js allows you to generate diagrams using a simple markdown-like syntax inside Markdown files. You can also use Mermaid to generate .svg or .png image files that you can add to your documentation. The target audience for this guide is anybody wishing to learn about Mermaid and/or how to create and add diagrams to Kubernetes documentation.

Recommended usage conventions for kubectl. Using kubectl in Reusable Scripts For a stable output in a script: Request one of the machine-oriented output forms, such as -o name, -o json, -o yaml, -o go-template, or -o jsonpath. Fully-qualify the version. For example, jobs.v1.batch/myjob. This will ensure that kubectl does not use its default version that can change over time. Don't rely on context, preferences, or other implicit states. Subresources You can use the --subresource beta flag for kubectl commands like get, patch, edit and replace to fetch and update subresources for all resources that support them.
