pyinfra turns Python code into shell commands and runs them on SSH servers, local machines, and Docker containers for fast, scalable infrastructure automation.
pyinfra is an infrastructure automation tool that converts Python code into shell commands and runs them on remote servers, local machines, or Docker containers. It solves the problem of managing and deploying infrastructure at scale by providing a fast, Python-based alternative to traditional configuration management systems. It supports both ad-hoc commands and declarative operations, enabling idempotent deployments and real-time debugging.
DevOps engineers, system administrators, and developers who need to automate server provisioning, configuration, and deployment across multiple environments. It is ideal for teams already using Python who prefer code over YAML for infrastructure management.
Developers choose pyinfra for its exceptional speed, Python-native syntax, and agentless architecture, which together offer a more flexible and performant alternative to tools like Ansible. Its ability to scale seamlessly from one server to thousands, combined with real-time output and idempotent operations, makes it a robust choice for modern infrastructure workflows.
🔧 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.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Scales predictably across thousands of hosts with parallel command execution, avoiding performance degradation as highlighted in the README.
Provides immediate stdin/stdout/stderr output with verbose flags (-vvv), enabling instant diagnosis of issues during runs.
Leverages any Python package for custom operations, offering code-driven workflows beyond YAML limitations.
Operates via SSH without remote agents and includes built-in connectors for Docker, Terraform, and Vagrant, simplifying multi-platform management.
Enables diffs and dry runs to preview changes before application, ensuring safe and predictable infrastructure modifications.
Has fewer ready-to-use modules compared to tools like Ansible, often requiring custom Python code for complex tasks despite extensibility.
Requires proficiency in Python for writing deployments, which can be a steep learning curve for teams accustomed to declarative YAML or other languages.
While documentation exists, the ecosystem and third-party support are nascent, potentially slowing issue resolution and adoption.
