Thanks, will take a look at that curl thing. We are still using this and been working for us for ~15 years (python 2, ported to python 3) and this is just an example of how to take https://fabfile.org to the extreme but still is not the best way to do it. We only ~50 servers so it is not a massive fleet. The convenience of typing `fab <env> <role> <task>` to do things under control is still better than nothing :)
