alt Hacker News> Puppet or terraform or something more declarative would have been such a better alternative
Until you need to do something that isn't covered with its DSL, and you extend it with an external command execution declaration... At which point people will just write bash scripts anyway and use your declarative language as a glorified exec.
If you have 90-95% of everyone's needs (installing packages, compiling, putting files) covered in your DSL, and it has strong consistency and declarativeness, it's not that big of a problem if you need an escape hatch from time to time. Terraform, Puppet, Ansible, SaltStack show this pretty well, and the vast majority of them that isn't bash scripts is better and more maintainable than their equivalents in pure bash would be.
