Interesting subject, thank you! I have a cluster of 2 Orange Pis (16 GB RAM each) plus a Raspberry Pi. I think it's high time to get them back on my desk. I never had time to get very far with the setup due to a lack of time. It took so long to write the Ansible scripts/playbooks, but with Claude Code, it's worth a try now. So thanks for the article; it makes me want to dust it off!
