Описание: Numerous sample programs & examples demonstrating the application of python tools to streamline network automation.
With "Mastering Python Network Automation," you can streamline container orchestration, configuration management, and resilient networking with Python and its libraries, allowing you to emerge as a skilled network engineer or a strong DevOps professional.
From the ground up, this guide walks readers through setting up a network automation lab using the NS3 network simulator and Python programming. This includes the installation of NS3, as well as python libraries like nornir, paramiko, netmiko, and PyEZ, as well as the configuration of ports, hosts, and servers. This book will teach you the skills to become a proficient automation developer who can test and fix any bugs in automation scripts. This book examines the emergence of the service mesh as a solution to the problems associated with service-to-service communication over time.
This book walks you through automating various container-related tasks in Python and its libraries, including container orchestration, service discovery, load balancing, container storage management, container performance monitoring, and rolling updates. Calico and Istio are two well-known service mesh tools, and you'll find out how to set them up and configure them to manage traffic routing, security, and monitoring. Additional topics covered in this book include the automation of network policies, the routing of workloads, and the collection and tracking of metrics, logs, and traces. You'll also pick up some tips and tricks for collecting and visualizing Istio metrics with the help of tools like Grafana.
Key Learnings
Use of Istio for cluster traffic management, traffic routing, and service mesh implementation.
Utilizing Cilium and Calico to solve pod networking and automate network policy and workload routing.
Monitoring and managing Kubernetes clusters with etcd and HAProxy load balancers and container storage.
Establishing network automation lab with tools like NS3 emulator, Python, Virtual Environment, and VS Code.
Establishing connectivity between hosts, port connectivity, SSH connectivity, python libraries, NS3, and network encryption.

Многочисленные примеры программ и иллюстраций, демонстрирующие применение инструментов python для оптимизации сетевой автоматизации.
С помощью "Освоение сетевой автоматизации на Python" вы сможете упростить оркестровку контейнеров, управление конфигурацией и создание устойчивых сетей с помощью Python и его библиотек, что позволит вам стать квалифицированным сетевым инженером или сильным специалистом по DevOps.
Это руководство с самого начала знакомит читателей с настройкой лаборатории сетевой автоматизации с использованием сетевого симулятора NS3 и программирования на Python. Это включает в себя установку NS3, а также библиотек python, таких как nornir, paramiko, netmiko и PyEZ, а также настройку портов, узлов и серверов. Вы приобретете навыки, необходимые для того, чтобы стать опытным разработчиком автоматизации, который может тестировать и исправлять любые ошибки в сценариях автоматизации. В этой книге рассматривается появление service mesh как решения проблем, связанных с обменом данными между службами с течением времени.
В этой книге вы познакомитесь с автоматизацией различных задач, связанных с контейнерами, в Python и его библиотеках, включая оркестровку контейнеров, обнаружение служб, балансировку нагрузки, управление хранилищем контейнеров, мониторинг производительности контейнеров и текущие обновления. Calico и Istio - два хорошо известных инструмента service mesh, и вы узнаете, как их настроить для управления маршрутизацией трафика, безопасностью и мониторингом. Дополнительные темы, рассматриваемые в этой книге, включают автоматизацию сетевых политик, маршрутизацию рабочих нагрузок, а также сбор и отслеживание показателей, журналов и трассировок. Вы также узнаете несколько советов и хитростей по сбору и визуализации показателей Istio с помощью таких инструментов, как Grafana.
Ключевые знания
Использование Istio для управления кластерным трафиком, маршрутизации трафика и реализации сервисной сетки.
Использование Cilium и Calico для решения задач pod networking и автоматизации сетевой политики и маршрутизации рабочей нагрузки.
Мониторинг и управление кластерами Kubernetes с помощью балансировщиков нагрузки etcd и HAProxy и контейнерного хранилища.
Создание лаборатории сетевой автоматизации с использованием таких инструментов, как эмулятор NS3, Python, Virtual Среда и VS-код.
Установление соединения между хостами, подключение к порту, подключение по SSH, библиотеки python, NS3 и сетевое шифрование.
