Ansible 2 w praktyce. Automatyzacja infrastruktury, zarządzanie konfiguracją i wdrażanie aplikacji

Daniel Oh, James Freeman, Fabio Alessandro Locati

Framework Ansible jest potężnym narzędziem służącym do automatyzacji wdrożeń oprogramowania i zarządzania jego konfiguracjami. Oferuje proste i bardzo przydatne funkcje przeznaczone do automatyzacji wielowarstwowych środowisk za pomocą komunikacji niewymagającej agenta. Przydaje się także do obsługi ciągłej integracji i wdrażania oprogramowania (CI/CD) bez żadnego przestoju. Może służyć do różnych celów: przygotowania infrastruktury jako kodu, wdrożeń aplikacji czy automatyzacji codziennych, czasochłonnych zadań. Ta książka jest przeznaczona dla osób zajmujących się automatyzacją - od żmudnych codziennych zadań po złożone wdrożenia infrastruktury jako kodu. Ten praktyczny przewodnik pozwoli na sprawne rozpoczęcie korzystania z frameworka Ansible 2.9. Na początku pokazano, jak go zainstalować i skonfigurować, później zaprezentowano proste, jednowierszowe polecenia automatyzacji, aby stopniowo wprowadzać czytelników do tworzenia własnego kodu rozszerzającego możliwości Ansible, a nawet automatyzującego infrastrukturę chmury i kontenerów. Znalazło się tu mnóstwo praktycznych przykładów kodu, a zdobyte umiejętności pozwolą na korzystanie z Ansible w sposób skalowalny, powtarzalny i niezawodny. W książce: podstawy pracy z frameworkiem Ansible konfiguracja zależności i zmiennych bazujących na rolach unikanie najczęściej popełnianych błędów podczas tworzenia kodu w Ansible tworzenie modułów i wtyczek dla Ansible rozwiązywanie problemów podczas wykonywania scenariuszy Ansible Żmudne i nudne? Ansible wykona to za Ciebie!

Practical Ansible 2. Automate infrastructure, manage configuration, and deploy applications with Ansible 2.9

Daniel Oh, James Freeman, Fabio Alessandro Locati

Ansible enables you to automate software provisioning, configuration management, and application roll-outs, and can be used as a deployment and orchestration tool. While Ansible provides simple yet powerful features to automate multi-layer environments using agentless communication, it can also solve other critical IT challenges, such as ensuring continuous integration and continuous deployment (CI/CD) with zero downtime.In this book, you'll work with Ansible 2.9 and learn to solve complex issues quickly with the help of task-oriented scenarios. You'll start by installing and configuring Ansible on Linux and macOS to automate monotonous and repetitive IT tasks and get to grips with concepts such as playbooks, inventories, and network modules. As you progress, you'll gain insight into the YAML syntax and learn how to port between Ansible versions. In addition to this, you'll also understand how Ansible enables you to orchestrate multi-layer environments such as networks, containers, and the cloud.By the end of this Ansible book, you'll be well - versed in writing playbooks and other related Ansible code to overcome just about all of your IT challenges, from infrastructure-as-code provisioning to application deployments, and even handling the mundane day-to-day maintenance tasks that take up so much valuable time.
