Cinc/Chef lab

Isolated sandbox (Incus VMs, not LXC —Linux system containers— — Chef manages the full OS state: sysctl, mounts, kernel modules) to learn Chef/CINC (free distribution of Chef) without risking production. Tested on both architectures of the cluster.

incus launch images:ubuntu/24.04 cinc-lab-x86 --vm --target=@x86-nodes -c limits.cpu=2 -c limits.memory=2GiB
incus launch images:ubuntu/24.04 cinc-lab-arm --vm --target=@arm64-nodes -c limits.cpu=2 -c limits.memory=2GiB

Cookbooks in cinc-lab/cookbooks/.

Also evaluated: installing Cinc/Chef as configuration management for the whole HomeLab — rejected in favor of Ansible (agentless, YAML, gentler learning curve) + OpenTofu (Incus provider) for 3 nodes. Cinc stays as a learning lab, not as a production component for now.
