pyinfra automates infrastructure super fast at massive scale

Documentation • Getting Started • Examples • Help & Support • Contributing

pyinfra automates/provisions/manages/deploys infrastructure. It can be used for ad-hoc command execution, service deployment, configuration management and more. Design features include:

• 🚀 Super fast execution over thousands of hosts with predictable performance.
• 🚨 Instant debugging with stdout & stderr output on error or as required (-v|-vv|-vvv).
• 📦 Extendable with any Python package as configured & written in standard Python.
• 💻 Agentless execution against SSH/Docker/subprocess/winrm hosts.
• ❗️ Two stage process that enables --dry runs before executing any changes.
• 🔌 Integrated with Docker, Vagrant/Mech & Ansible out of the box.

When you run pyinfra you'll see something like (non animated version):

Install pyinfra with pipx (recommended) or pip:

pipx install pyinfra

Now you can execute commands on hosts via SSH:

pyinfra my-server.net exec -- echo "hello world"

Or execute in Docker, on the local machine, and other connectors:

pyinfra @docker/ubuntu exec -- echo "Hello world"
pyinfra @local exec -- echo "Hello world"

As well as executing commands you can define state using operations:

# Install iftop apt package if not present
pyinfra @docker/ubuntu apt.packages iftop update=true _sudo=true

Which can then be saved as a Python file like deploy.py:

from pyinfra.operations import apt

apt.packages(
    name="Ensure iftop is installed",
    packages=['iftop'],
    update=True,
    _sudo=True,
)

The hosts can also be saved in a file, for example inventory.py:

targets = ["@docker/ubuntu", "my-test-server.net"]

And executed together:

pyinfra inventory.py deploy.py

Now you know the building blocks of pyinfra! By combining inventory, operations and Python code you can deploy anything.
