Ansible is abysmal. I don't know why anyone still chooses it. It's a mess of yaml and what feels like a million yaml files that is always extremely hard to follow. Honestly writing some python, or bash is a lot easier to follow, read, and understand. The only thing it has going for it is the inventory system. I wish ansible would die already.
The tips mentioned in the article are helpful, but still beyond the initial development of roles, maintaining roles is a pain no one can alleviate. It is the perl of automation. I wish people would stop using it. I've yet to start a job where people haven't regretted going towards ansible.
Do you have any suggestions on good set of sdk or library for writing those automations in python? The main reason for using ansible for me was always because of their rich built in tasks. I tried writing in python my automations but even very simple tasks were needed too much effort compare to ansible so I had to return back.
