Ansible is a lightweight batch configuration management tool for agentless, because of the relatively late (13) development based on ansible less relevant documents, so here are some small experiments, combined with the existing data and source code, explore the Ansible two times development.The contents of the essay are divided into three parts.

Preface Two previous articles talk about ansible deployment and use of ansible modules respectively. They have an initial understanding of ansible. This article focuses on introducing playbook.For details about ansible deployment, click ansible first: DeploymentAnsible modul
