Python: tool to keep track of deployments

Question

I'm looking for a tool to keep track of "what's running where". We have a bunch of servers, and on each of those a bunch of projects. These projects may be running on a specific version (hg tag/commit nr) and have their requirements at specific versions as well.

Fabric looks like a great start to do the actual deployments by automating the ssh part. However, once a deployment is done there is no overview of what was done.

Before reinventing the wheel I'd like to check here on SO as well (I did my best w/ Google but could be looking for the wrong keywords). Is there any such tool already?

(In practice I'm deploying Django projects, but I'm not sure that's relevant for the question; anything that keeps track of pip/virtualenv installs or server state in general should be fine)

many thanks,

Klaas

EDIT FOR TEMP. SOLUTION

==========

For now, we've chosen to simply store this information in a simple key-value store (in our case: the filesystem) that we take great care to back up (in our case: using a DCVS). We keep track of this store with the same deployment tool that we use to do the actual deploys (in our case: fabric)

Passwords are stored inside a TrueCrypt volume that's stored inside our key-value store.

I will still gladly accept any answer when some kind of Open Source solution to this problem pops up somewhere. I might share (part of) our solution somewhere myself in the near future.

Answer 1

pip freeze gives you a listing of all installed packages. Bonus: if you redirect the output to a file, you can use it as part of your deployment process to install all those packages (pip can programmatically install all packages from the file).

I see you're already using virtualenv. Good. You can run pip freeze -E myvirtualenv > myproject.reqs to generate a dependency file that doubles as a status report of the Python environment.
