Fabric is a great tool at first, but the problem is that it's always procedural. Want a deploy script? Write it. No other way around that.

Something that's more declarative is definitely superior. Why? Because it will be shorter and easier to debug. I am not a fan of `git push` as a deployment strategy (because git is a version control tool, not a deployment tool), but it does force you to create and use a system that's by definition declarative. This is why I use dokku for my new projects.

Because, as mentioned, I already deploy in one line:

    git push deploy/uat

and I didn't have to write a single deployment script to achieve it.

Plus, by using Dokku I get the benefits of containerised apps.
