How to build and deploy Python web applications

I have a Python web application consisting of several Python packages. What is the best way of building and deploying this to the servers?

Currently I'm deploying the packages with Capistrano, installing the packages into a virtualenv with bash, and configuring the servers with puppet, but I would like to go for a more Python based solution.

I've been looking a bit into zc.buildout, but it's not clear for me what I can/should use it for.

Answer 1

Depends on what Your infrastructure is. We're just using debian packages and buildbot to make them.

On other setups, I use Fabric scripts. As for format, I'm just using tbz2 files, but I've heard about people just depoloying eggs.

I'd strongly recommend having proper build and having BuildBot/Hudson to build packages, as using SCM beats the purpose and encourage bad practices.

Answer 5

I use Mercurial as my SCM system, and also for deployment too. It's just a matter of cloning the repository from another one, and then a pull/update or a fetch will get it up to date.

I use several instances of the repository - one on the development server, one (or more, depending upon circumstance) on my local machine, one on the production server, and one 'Master' repository that is available to the greater internet (although only by SSH).

The only thing it doesn't do is automatically update the database if it is changed, but with incoming hooks I could probably do this too.
