It also includes tutorials for multi-container orchestration and a DevOps guide focused on CI/CD automation and image optimization. The material covers a broad

Socket.IO Client is a real-time WebSocket client library that establishes persistent bidirectional connections to a server, with automatic fallback to HTTP long-polling when WebSocket connections are unavailable. It provides an event-based bidirectional messaging framework where clients and servers exchange named events with serializable data, supporting acknowledgements and timeouts for reliable communication. The client distinguishes itself through automatic reconnection with exponential backoff, maintaining connection reliability by monitoring health and reconnecting with increasing delays

Bubblewrap is a Linux sandbox runner that creates lightweight, isolated execution environments for running untrusted applications. It combines Linux user, mount, network, PID, and UTS namespaces with seccomp-BPF system call filtering to restrict filesystem, network, process, and inter-process communication access. The project provides comprehensive process isolation by giving each sandbox its own private tmpfs root with selective bind-mounts, a separate network stack containing only a loopback interface, an independent process ID space, and remapped user and group identifiers. It applies secc

CRI-O is an open-source container runtime that implements the Kubernetes Container Runtime Interface (CRI) to manage container images, pods, and containers on cluster nodes using OCI-compatible runtimes. It serves as a node-level container manager that handles image pulling, container lifecycle, and resource monitoring for Kubernetes clusters, running containers according to the Open Container Initiative specifications. The runtime distinguishes itself through live configuration reloading that applies changes to runtime definitions, registry mirrors, and TLS certificates without restarting th

Try هي أداة لإدارة بيئات الصدفة المؤقتة وتشغيل الأوامر داخل بيئة معزولة (Sandbox). تستخدم OverlayFS ومساحات أسماء Linux لمنع العمليات من تغيير النظام المباشر، وتعمل كصدفة أوامر معزولة ومدقق لتغييرات نظام الملفات. يسمح المشروع للمستخدمين بالتقاط تعديلات الملفات في طبقة مؤقتة وفحص تلك التغييرات قبل اتخاذ قرار بتطبيقها أو التخلص منها. يدعم سير عمل تدقيق الإضافات والتعديلات، ثم دمج التغييرات التي تم التحقق منها مرة أخرى في نظام ملفات المضيف. توفر الأداة قدرات لصدفات البيئة المعزولة التفاعلية، وإدارة مجلد البيئة المعزولة المخصص، والقدرة على دمج مجلدات تراكب متعددة في بيئة واحدة ذات طبقات. كما تتضمن نصوص إكمال الصدفة لإكمال الأوامر والأعلام تلقائياً.

Tetragon هي مجموعة أدوات أمنية ومراقبة تعتمد على eBPF مصممة لبيئات Linux وKubernetes. تعمل كمدير لسياسات الأمان، وعميل للمراقبة، ومحرك لفرض القواعد، حيث ترتبط بوظائف النواة (Kernel functions) ونقاط التتبع لاكتشاف تصعيد الامتيازات، وهروب الحاويات، والأنشطة غير المصرح بها في النظام. يتميز المشروع بقدرته على فرض القواعد في الوقت الفعلي داخل النواة، مما يسمح بإنهاء العمليات الضارة بشكل متزامن أو تعديل قيم إرجاع الوظائف قبل اكتمال استدعاء النظام. يوفر تكاملاً عميقاً مع Kubernetes من خلال مزامنة هويات الحاويات وربط أحداث النواة منخفضة المستوى مباشرة بـ Pods وNamespaces. تغطي قدراته الأوسع تدقيق استدعاءات النظام الشامل، وتتبع اتصالات الشبكة، ومراقبة سلامة الملفات. يدعم النظام إدارة السياسات الديناميكية ويوفر أدوات تشخيصية لمراقبة أداء BPF واستخدام الموارد. يتم دعم النشر عبر مجموعات Kubernetes باستخدام Helm charts، بالإضافة إلى الحاويات المستقلة وحزم أنظمة التشغيل الأصلية.

Pouch is a Linux container runtime and OCI container engine designed to execute containerized applications. It functions as a Kubernetes container runtime, integrating with orchestrators to manage the lifecycle of pods and isolated application environments. The project features a peer-to-peer image distribution system to deliver large container images across large-scale clusters while reducing bandwidth load. It also provides support for legacy Linux kernel versions, allowing modern container runtimes to maintain compatibility with older hardware. The runtime implements application isolation

This project is a comprehensive command-line reference and toolkit designed for Linux system administration and network security assessment. It provides a collection of technical snippets and operational guides focused on managing remote environments, orchestrating shell sessions, and executing administrative tasks through native terminal utilities. The repository distinguishes itself by offering specialized techniques for stealthy operations and infrastructure manipulation. It covers methods for establishing encrypted tunnels to bypass firewalls, obfuscating process identities and command hi

The project provides an open container runtime specification and standardized schema for defining container configurations, namespaces, resource limits, security policies, and filesystem mounts across platforms. It outlines the formal configuration formats, lifecycle operations, and execution environments necessary for portable, isolated container workloads. The specification covers container lifecycle management protocols and structured rules governing container creation, execution startup, process signaling, state tracking, and resource teardown. It standardizes local bundle packaging and

CRIU is a Linux process checkpointing tool and state manager used to freeze running applications and save their memory and state to disk for later restoration. It functions as a container migration engine and an OCI checkpoint image converter, allowing the live state of running containers to be transferred between different hosts. The project distinguishes itself through its ability to persist network connectivity, acting as a TCP connection state persister that saves and reconstructs network socket states to maintain active communication after a restart. It further enables the distribution o

This project provides a framework for AI agent orchestration and context management, enabling the deployment of specialized AI personas and subagents to solve multi-step technical goals. It centers on managing specialized agents with isolated contexts and role-based prompts to handle domain-specific tasks.
