Pyinfra is a fully automated deployment python library

What is the Pyinfra library.

  • Pyinfra is a Python library for automated deployment and configuration. It allows users to describe server architecture, software configuration and deployment processes in a declarative manner. Pyinfra aims to become one of the tools for Infrastructure as Code.

Use and installation:

pip install pyinfra
  • To start using pyinfra, you need to write Python scripts containing host definitions and task descriptions, and run these scripts to perform deployment and configuration operations.

The following is a sample pyinfra script for installing an Nginx server:

from pyinfra.operations import server

nginx_installation = server.packages(
    name='Install Nginx',

if __name__ == '__main__':

core advantages:

Pure Python:

  • Pyinfra uses Python as the development language, making it easier to write, maintain and extend deployment scripts.

easy to understand:

  • Describe server configuration and deployment tasks through declarative syntax, reducing the learning curve.

Various connectors:

  • Supports multiple connection methods such as SSH and local Shell, suitable for different scenarios.

Advantages and Disadvantages:


  1. Easy to learn and use
  2. Pure Python implementation
  3. Support multiple connection methods


  • The community is relatively small and the ecosystem may not be as mature as other similar tools

Advanced Features:

Pyinfra offers a range of advanced features, including:

1. Execute tasks in parallel

from pyinfra import host, local, inventory

# Define hosts
host1 = host('')
host2 = host('')

# Run tasks in parallel on multiple hosts

with host1.get_implementation() as host_impl1, host2.get_implementation() as host_impl2:
    host_impl1.run_shell_command('echo "Task on host1"')
host_impl2.run_shell_command('echo "Task on host2"')

2. Multi-host management:

from pyinfra.operations import server

hosts = ['', '']

for host_name in hosts:
            name='Create user',

3. Use built-in modules:

from pyinfra import host, local

# Install packages on localhost
    name='Install packages',
    packages=['nginx', 'postgresql']
  • These examples demonstrate Pyinfra’s advanced features, including parallel execution of tasks, multi-host management, and the use of built-in modules to simplify the deployment and configuration process. These features make Pyinfra a powerful and flexible automated deployment tool.


  • In Python, Pyinfra plays an important role, enabling developers to automate deployment and configuration management in a declarative manner, thereby reducing manual errors and repetitive work. Its pure Python implementation and simplicity of use make Pyinfra Become a powerful infrastructure-as-code tool.
