pyinfra 命令

常用示例

说明

pyinfra automates infrastructure provisioning and configuration management using Python. Deploy scripts are written as regular Python files that describe desired system state through operations like installing packages, managing files, configuring services, and executing commands across groups of servers. The tool connects to targets over SSH without requiring agents on remote machines, making it lightweight to adopt. An inventory file defines target hosts and groups, while deploy scripts specify what operations to run. The --dry flag previews changes before applying them, and the fact command gathers system information from targets for conditional logic in deployments.
