Visão Geral

Curso Introductory and Intermediate Ansible Configuration and Administration. Ansible é um poderoso mecanismo de código aberto para automatizar o gerenciamento de configuração, o provisionamento de software e a implantação de aplicativos. Este Curso Introductory and Intermediate Ansible Configuration and Administration ensina aos participantes noções básicas do Ansible, incluindo como criar playbooks, aproveitar módulos e configurar funções. Os alunos então levam suas habilidades para o próximo nível com tópicos avançados, incluindo construção de manuais, utilização de módulos e gerenciamento de nós e muito mais. Além disso, este curso cobre a Torre Ansible.

• Projete uma estratégia de 'melhores práticas' para usar recursos Ansible
• Explore o Ansible Tower como uma solução para gerenciar graficamente o Ansible em toda a empresa
• Execute a configuração avançada para um nó de controle Ansible e nós gerenciados
• Use condicionais, loops, filtros e loopbacks em playbooks
• Controle a saída ad-hoc e do manual com plug-ins de retorno de chamada
• Crie e implemente definições de inventário dinâmico
• Implementar recursos e dependências de funções reutilizáveis
• Controle as operações do Ansible Core com parâmetros de tempo de execução
• Crie modelos para escrever um módulo personalizado Ansible
• Adicione documentação a um módulo personalizado do Ansible
• Criar e usar variáveis ​​de fatos locais
