Congrats on shipping 3.8.0!

If you're a software engineer who wants to setup and maintain infrastructure, give PyInfra and Pulumi a go!

Huge fan of PyInfra. For my homelab, I use Pulumi with Python and PyInfra to build fully declarative intent based infrastructure. You can use actual software engineering principles like composition, inheritance, DI to setup and wire your infrastructure and services. One of the benefits of this is your infrastructure and services are now self documenting (have them write out a mermaid diagram!) and easily testable using pytest (from cheap unit tests to extensive integration tests (I use Incus)).

Instead of Pulumi, I originally used Terraform CDK with Python before CDK got IBM'd. The migration to Pulumi was refreshingly painless. My original reason for not choosing Pulumi was the crippled state of the open source, self hosted backend support a decade ago but it looks like that is now way more mature and less crippled.

PyInfra is a breath of fresh air compared to Ansible - its not just fast, it's more Pythonic, so IDE features actually work, readable, maintainable, debuggable. I call it infrastructure for software engineers.

If anyone wants to use an AI agent to try out PyInfra - One issue I've faced is that PyInfra was rearchitected in v2 (and some more in v3?) but what belongs in v1 vs v2 vs v3 isn't very clear, so an AI agent could spend a lot of time writing v1 code, having it fail and iterate to v2 and then to v3.

The official site uses the version in the URL as the namespace but it seems like the SOTA AI agents don't pay much attention to that.

Maybe writing a llms.txt for PyInfra v2, or v3 would be an extremely useful task to help with onboarding newcomers?

Disclosure: PyInfra core contributor here. We just shipped 3.8.0.

PyInfra is an agentless infrastructure automation tool. Same job description as Ansible, Salt, Chef. SSH into hosts, describe desired state, it diffs and converges. No agent, no central server, no daemon.

The difference: your "playbook" is just Python. Not Python cosplaying as YAML. Not Jinja smuggled inside YAML inside a Helm chart inside a Kustomize overlay. Actual Python:

    from pyinfra.operations import apt, files, server

    apt.packages(packages=["nginx"], update=True)
    files.template(src="nginx.conf.j2", dest="/etc/nginx/nginx.conf")
    server.service(service="nginx", running=True, enabled=True)

Idempotent operations. Facts gathered from hosts, branched on with normal `if` statements. Real loops, real imports, a real debugger, real type hints. Your editor autocompletes arguments because, brace yourself, they are just function signatures. About YAML. Wonderful format. For about eleven minutes. Then someone needs an `if`, and you have `{% if %}` inside a string inside a list inside a map. Then someone types `no` as a country code for Norway and it ships to prod as `False`. Then someone indents with a tab and the parser dies without saying where. Congratulations, you reinvented a programming language. Badly. The honest move is to admit you wanted code, then write code.

PyInfra skips the eleven good minutes and goes straight to code.

Release notes in the link. Happy to answer questions.

Infrastructure as Code, not infrastructure as YAML.

There is a PR open for llms.txt and llms-full.txt. We'll try to merge it soon!

Disclosure: another contributor here.

It's amazing to see more contributors!

TBH, I was worried a few years ago that there was basically just one (original) contributor. This now gives me added trust that I'm taking the right decision to lean heavily into it.

I hope more people start using pyInfra.

Thank You for your contribution and attention!

		Indeed! (I am that original contributor :)), lots of work ongoing to address this, we now have a small maintainers group and are sharing out review and release loads.

		Thanks! There are currently 3 active maintainers incl. the creator of pyinfra. But there are many more contributors incl. repeat contributors.

+100 to pulumi, I love it with TypeScript
