pyinfra turns Python code into shell commands and runs them on your servers. Execute ad-hoc commands and write declarative operations. Target SSH servers, local machine and Docker containers. Fast and scales from one server to thousands. Think ansible but Python instead of YAML, and a lot faster.

Why pyinfra? Design features include:
+ **Super fast** execution over thousands of hosts with predictable performance.
+ **Instant debugging** with realtime stdin/stdout/stderr output (`-vvv`).
+ **Idempotent operations** that enable diffs and dry runs before making changes.
+ **Extendable** with the entire Python package ecosystem.
+ **Agentless execution** against anything with shell access.
+ **Integrated** with connectors for Docker, Terraform, Vagrant and more.
## Quickstart
Install pyinfra with [`uv`](https://docs.astral.sh/uv/):
```
uv tool install pyinfra
```
Now you can execute commands on hosts via SSH:
```sh
pyinfra my-server.net exec -- echo "hello world"
```
Or target Docker containers, the local machine, and other [connectors](https://docs.pyinfra.com/page/connectors.html):
```sh
pyinfra @docker/ubuntu exec -- echo "Hello world"
pyinfra @local exec -- echo "Hello world"
```
As well as executing commands you can define state using [operations](https://docs.pyinfra.com/page/operations.html):
```sh
# 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`:
```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`:
```py
targets = ["@docker/ubuntu", "my-test-server.net"]
```
And executed together:
```sh
pyinfra inventory.py deploy.py
```
Now you know the building blocks of pyinfra! By combining inventory, operations and Python code you can deploy anything.
See the more detailed [getting started](https://docs.pyinfra.com/page/getting-started.html) or [using operations](https://docs.pyinfra.com/page/using-operations.html) guides. See how to use [inventory & data](https://docs.pyinfra.com/page/inventory-data.html), [global arguments](https://docs.pyinfra.com/page/arguments.html) and [the CLI](https://docs.pyinfra.com/page/cli.html) or check out the [documented examples](https://docs.pyinfra.com/page/examples.html).
