Kubectl Node Shell - الحصول على صلاحيات الجذر…

هذا المشروع عبارة عن إضافة سطر أوامر لـ Kubernetes توفر وصولاً مباشراً إلى صدفة الجذر (root shell) لنظام التشغيل المضيف الأساسي لعقدة الكتلة. تم تصميمه لتسهيل المهام الإدارية، وصيانة النظام، وعمليات التشخيص على العقد، بما في ذلك تلك التي تشغل أنظمة تشغيل غير قابلة للتغيير أو محسنة للحاويات وتفتقر إلى بيئات الصدفة الأصلية.

تعمل الأداة عن طريق جدولة حاويات مؤقتة ومميزة ديناميكياً تشترك في مساحات أسماء العمليات والشبكة ونظام الملفات للمضيف. من خلال الاستفادة من قيود تقارب العقدة (node affinity)، فإنه يضمن تنفيذ جلسات التشخيص هذه على المضيف المستهدف المحدد، مما يسمح للمستخدمين بالتفاعل مع دليل الجذر الخاص بالعقدة وعمليات النظام كما لو كانوا مسجلين محلياً.

بعيداً عن جلسات الصدفة التفاعلية، تدعم الأداة تنفيذ الأوامر عن بعد لأتمتة تغييرات التهيئة أو استرداد بيانات التشخيص عبر الكتلة. كما توفر قدرات لإرفاق وحدات تخزين مستمرة بهذه البيئات المؤقتة، مما يتيح استعادة البيانات ونقل المعلومات بين أجهزة العقدة المحلية وأنظمة التخزين الخارجية.

Features

Kubernetes Node Debugging - Provides direct host-level access to troubleshoot hardware and system issues on Kubernetes nodes.
Device Shell Access - Grants root-level shell access to the host operating system of a Kubernetes node for administrative and diagnostic tasks.
Cluster Administration - Facilitates cluster-wide administration by allowing remote command execution across node host environments.
Node Affinity Rules - Uses node affinity rules to ensure diagnostic pods are scheduled on the specific target host requiring maintenance.
Workload Scheduling - Schedules ephemeral diagnostic pods onto specific cluster nodes to facilitate system-level maintenance tasks.
Infrastructure Debugging Utilities - Enables inspection and repair of immutable or container-optimized operating systems by launching temporary diagnostic environments.
Kubernetes Cluster Management - Acts as a maintenance utility for managing node infrastructure and executing administrative tasks within a cluster.
Root Filesystem Mounting - Mounts the host root filesystem into a container to enable direct inspection and modification of system files.
Remote Command Execution - Executes remote commands and scripts on host nodes to automate configuration changes and retrieve diagnostic data.
Namespace-Based Resource Sharings - Joins host process and network namespaces to allow diagnostic tools to interact directly with the underlying node environment.
Ephemeral Sidecar Injections - Injects privileged ephemeral sidecar containers into the node environment to bypass OS limitations for diagnostic access.
Troubleshooting Utilities - Offers diagnostic capabilities for inspecting and repairing nodes that lack native shell environments.

Karmada is a Kubernetes multi-cluster orchestrator and multi-cloud cluster manager designed to deploy and manage cloud-native applications across multiple clusters and cloud providers. It serves as a centralized control plane that functions as a resource propagator and workload scheduler, coordinating resources across public clouds, on-premises data centers, and edge locations. The project distinguishes itself through a policy-based engine that distributes applications using affinity, topology constraints, and resource quotas. It provides specific capabilities for multi-region disaster recove

siderolabs/talos

Talos is a minimal, immutable Linux distribution designed specifically for deploying and managing Kubernetes clusters. It functions as an API-driven infrastructure manager that replaces traditional shell access with a declarative gRPC interface to control operating system state and configuration. The system is distinguished by its use of a read-only root filesystem and a security-hardened kernel, which removes standard GNU utilities to reduce the attack surface. It ensures environment consistency by distributing the operating system as versioned, signed images and utilizes TPM-backed verified

kubernetes-client/python

The Kubernetes Python Client is a programmatic interface for cluster automation and resource management. It provides a REST-based API client that maps method calls to HTTP verbs and JSON payloads to create, update, delete, and monitor workloads and infrastructure components. The client features dynamic schema mapping and resource mapping, allowing it to control custom objects and unique resource definitions without requiring pre-defined classes or static schemas. It supports YAML manifest parsing to convert structured files into compatible objects for bulk resource deployment. The toolset co

aylei/kubectl-debug

Kubectl-debug is a diagnostic utility for Kubernetes that enables deep inspection of running containerized applications. It functions by dynamically injecting ephemeral sidecar containers into existing pods, allowing users to troubleshoot processes and filesystems without modifying original production images. The tool manages the lifecycle of these diagnostic agents, ensuring they are created on demand and cleaned up automatically after an investigation session concludes. The project distinguishes itself by enabling shared namespace access, which allows diagnostic tools to join the process an
