This article explains how to create and use Kubernetes ServiceAccounts and User Accounts, configure kubeconfig files, and set up Role, RoleBinding, ClusterRole, and ClusterRoleBinding resources with practical YAML examples and command‑line instructions.
This guide demonstrates how to set up a Maven project with the Fabric8 Kubernetes Java client, configure minimal kubeconfig or ServiceAccount credentials, and use sample code to list namespaces, illustrating essential steps for connecting Java applications to a Kubernetes cluster with minimal configuration.
This guide explains how to run and switch between several Kubernetes clusters on a single server by configuring separate kubeconfig entries, adding clusters, users, and contexts, and using kubectl commands to manage each cluster efficiently.
This guide explains how to simulate and maintain two separate Kubernetes clusters on a single node by configuring kubeconfig files, adding clusters, users, and contexts, and switching between them to improve DevOps workflow efficiency.
This guide introduces kubecm, a Go‑based CLI tool for simplifying multi‑cluster kubeconfig management, covering its background, cross‑platform installation, core commands, command‑line auto‑completion, and practical usage screenshots to help Kubernetes users work more efficiently.
Learn how to install kubecm, merge multiple kubeconfig files, list, switch, and delete cluster contexts, enabling streamlined, single‑file management of many Kubernetes clusters directly from the command line without manually editing the config file, and see visual cues for the active context.
This guide shows how to wrap a service‑account token into a kubeconfig file, configure a cluster entry, credentials, and context on the master node, then use the generated kubeconfig to log into the Kubernetes dashboard, with an optional full‑access version.
This guide explains how to use the open‑source kubectx.manager tool to automatically merge several kubeconfig files into a single configuration, walk through installation, interactive merging steps, and recommends the powerful kubie plugin for fast context switching in Kubernetes environments.
