pyinfra is designed to automate/provision/manage/deploy servers at scale.
It can be used for ad-hoc command execution, service deployment, configuration management; you could say that pyinfra is like a combination of Ansible + Fabric. It is asynchronous, highly performant and can target thousands of hosts in parallel. It is entirely configured in Python, allowing for near-infinite extendability out of the box.
When you run pyinfra you'll see something like:
pyinfra was designed to deploy things in a consistent, debuggable and maintainable manner. Notable design decisions:
- properly agentless - even Python isn't required on the remote side (just a shell!)
- always print raw stderr on operation failure for instant debugging
-v
means print out remote stdout & stderr in realtime- outputs shell commands and files to upload
- two-step deploy that enables dry-runs
- fail fast where possible (eg touching a directory)
- uses pure, 100% Python for the inventory and deploy scripts
- with operations/hooks to safely use Python mid-deploy
