AWS Provision on the Flatcar Linux OS

Flatcar default network interface name might require specifying. It is most likely to be ens192 requiring passing the parameter --virtual-ip-interface ens192  to the dkp create cluster aws command. Otherwise, the cluster creation might fail because kube-vip can not configure the first control-plane virtual IP.

Flatcar Linux example

These flags are also shown in context on the Create Cluster page for either air-gapped or non-air-gapped environments:

dkp create cluster aws \
    --cluster-name ${CLUSTER_NAME} \
    --os-hint flatcar

For provisioning DKP on Flatcar, DKP configures cluster nodes to use Control Groups (cgroups) version 1. In versions prior to Flatcar 3033.3.x, a restart is required in order to apply the changes to the kernel. For more information, refer to the Flatcar documentation.

Also note that once Ignition runs, it is not available on reboot.
