pyinfra 0.4

Deploy stuff by diff-ing the state you want against the remote server.

pyinfra manages the state of one or more servers. It can be used for app/service deployment, config management and ad-hoc command execution. Deploys are asynchronous, highly performant and can target thousands of hosts in parallel. The inventory of servers and deploy state are written in Python, allowing for near-infinite extendability. pyinfra is available via the command line and as a Python API.

Design Features

pyinfra was designed to enable us 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
