Python3调用ansible模块和fastapi实现项目监控接口！

问题说明

2.而且项目可能在不同环境部署在不同的系统中
3.开发同学权限不足无法查看pid从而找到websocket 端口

python3 安装ansible 模块

pip3 install ansible_runner
pip3 install ansible_inventory
pip3 install ansible_playbook
pip3 install fastapi
pip3 install uvicorn

获取官方实例并修改

核心类介绍

导入类完整路径功能用途from ansible.module_utils.common.collections import ImmutableDict用于添加选项。比如: 指定远程用户remote_user=Nonefrom ansible.parsing.dataloader import DataLoader读取 json/ymal/ini 格式的文件的数据解析器from ansible.vars.manager import VariableManager管理主机和主机组的变量管理器from ansible.inventory.manager import InventoryManager管理资源库的，可以指定一个 inventory 文件等from ansible.playbook.play import Play用于执行 Ad-hoc 的类 ,需要传入相应的参数from ansible.executor.task_queue_manager import TaskQueueManageransible 底层用到的任务队列管理器ansible.plugins.callback.CallbackBase处理任务执行后返回的状态from ansible import context上下文管理器，他就是用来接收 ImmutableDict 的示例对象import ansible.constants as C用于获取 ansible 产生的临时文档。from ansible.executor.playbook_executor import PlaybookExecutor执行 playbook 的核心类from ansible.inventory.host import Group对 主机组 执行操作 ，可以给组添加变量等操作，扩展from ansible.inventory.host import Host对 主机 执行操作 ，可以给主机添加变量等操作，扩展
