tachyon's Introduction

tachyon

Tachyon is an experimental configuration management tool inspired by ansible implemented in golang.

Ok.. why?

I find the best way to learn something is to try to implement it. I'm curious about ansible's model for configuration management and as a fun weekend project began I this project.

Is this usable?

If you need to run some yaml that executes commands via shell/command, sure! Otherwise no. I'll probably continue to play with it, adding more functionality and fleshing out some ideas I've got.

Oohh what ideas?

Exploit golang's single binary module to bootstrap machines and run plays remotely.
Use golang's concurrency to make management of large scale changes easy.
Use github.com/evanphx/ssh to do integrated ssh
Allow creation of modules via templated tasks

Is that a lisp directory I see?

It is! ansible uses python as it's implementation lang and thus also uses it as it's runtime eval language. Obviously I can't do that and I don't wish to runtime eval any golang code. Thus I have opted to embed a simple lisp intepreter (taken and modified from https://github.com/janne/go-lisp) to run code. For instance:

name: Tell everyone things are great
action: shell echo wooooo!
when: $(== everything "awesome")

What should I do with this?

Whatever you want. Play around, tell me what you think about it. Send PRs for crazy ass features!

Please don't call this a port

Call this a different tool, there are lots of different things here.

Thanks!

Could you add the LICENSE file?

Hi @vektra, thanks for a nice software!
Could you add the LICENSE file?

Choosing an Open Source License might helps for choosing a license.

Use `otto`, the JS interpreter instead of LISP!

Just because there's a larger public with js knowledge :)

Still Maintained?

Is this project still maintained?

want to join you

I like tachyon!! I am a golang developer, can I join your organization?

More code comments, please!

Hey there, I'd be interested in using code from this package or contributing to it. However, a lot of source files have zero comments or sometimes just one. Would the author mind filling some in? Thank you!

Failing travis build

Hey there, your Travis build is failing and it looks like a configuration issue (rather than a test failure). Might want to check it out!

Question: why no user-side golang code for the tasks / playbooks?

Hello there.
You project seems to be the only CMS written in Go at the moment. So it would be nice to hear some elaboration on this bit of your README file:

don't wish to runtime eval any golang code

As being something important / worthwhile to comment about in terms of feasibility, some technical analysis.

The thing is that I do find ansible can be very slow... and it's based on python. It would be great to keep the successful ideas of ansible while improving the performance / execution time. Maybe you do already achieve right now quite a good performance with your stated Lisp interpreter. Unfortunately I can't cope with lisp myself. And I suspect it's also a view shared by many others. Tried lisp with emacs and just hated it. Too many ((())) brackets.

So my question really is: what would a GO-based CMS actually look like if it were like Ansible?

We would need the host control machine to have golang (in the same way that ansible requires python as a dependancy). In order to compile user code fragments (modules, user tasks, playbooks) into runtime executable(s). Perhaps cached. Then to run them either locally on the control machine (to exec sequences of SSH cmds / copy over shell scripts) or else to transfer them onto the target machine to be executed directly there. Depending if the target machine's architecture can be compiled or not.

It is feasible? Well I don't know that. Would it work? Don't know. But I think that using the popular implementation language GO throughout may help to gain more interest / community momentum from outside contributors.
