ansible deployment

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. Playboo

Playbook-Introduction: Playbooks is a mode different from the ansible command line execution mode, and its functions are more powerful and flexible. In simple terms, playbook is a very simple configuration management and multi-host deployment system. Unlike any existing mode, it can be used as a suitable basis for deploying complex applications. Playbook can be customized and executed in sequence according

A description of the application scenarioDo you have this? A requirement: The number of ports used by Java programs on many servers is compared with the normal values.You can use the following command to get the result:Netstat-tulnp|grep java|wc-lBut a lot of servers, each manual to execute this command is not realistic. So think of using ansible batch to execute, ansible use Paramiko to SSH login server ex

Objective:Ansible results By default is output to the CLI terminal and log inside, used to saltsatck the returners data callback, also very much like Ansible also have, at first did not know this function, oneself also simple to achieve such a function.My implementation is to do some output logic inside the module. When using the Ansible Runner API, it is runner the code at the back and finally adds a secti
