- config templating engine (ignition) - static asset server - matches servers by labels (e.g. MAC address) to Profiles with iPXE configs, Container Linux configs
in /var/lib/matchbox/assets/coreos - structure: /var/lib/matchbox assets/ - free form, files, hashes groups/ - control plane, master groups ignition/ - config mgmt on Container Linux profiles/
location as cluster - use OEM version of Container Linux if needed, e.g. for packet - learned many lessons on k8s internals especially on control plane: etcd, manifests
