I personally used Chef, Salt and Ansible, Ansible was the easiest to start with, but also the least dependable one, and didn't deliver on one thing it supposed to - reproducibility. On the same image it sometimes succeeded and sometimes failed. This was happening on Amazon Linux 2, and basically once in a while yum database got corrupted. I'm suspecting there was a conflict between yum run by Amazon Linux 2 on boot, and ansible didn't respect locks acquired by yum?
