The process will setup DHCP dnsmasq on opnsense to boot the correct ipxe file depending on the architecture Then ipxe will chainload to either a mac-specific ipxe boot file or the fallback inventory boot file Then a kickstart pre script will setup the cluster ssh key to allow ssh connections to the machine and also setup and start harmony_inventory_agent to allow being scraped Note: there is a bug with the inventory agent currently, it cannot find lsmod on centos stream 9, will fix this soon
Here lies all the data files required for an OKD cluster PXE boot setup.
This inclues ISO files, binary boot files, ipxe, etc.
TODO as of august 2025 :
harmony_inventory_agentshould be downloaded from official releases, this embedded version is practical for now though- The cluster ssh key should be generated and handled by harmony with the private key saved in a secret store
