Sure, legacy exists but as a systems principal engineer I would always look to improve the platform. Puppet/chef/ansible all the problems those solved are kind of moot with a kubernetes ecosystem. The only thing they might be useful for would be installing the software to get those nodes added and maybe security updates in you’re running 1k+ of bare metal. And something that could all be solved with something light like dancers shell. At home I’ve even just moved to k3 since the containerize is just so much more consistent. Ansible not maintaining state is also a massive headache.
