K0smotron allows you to configure k0s via spec.k0sConfig field. If empty, the default configuration will be used.

Note: Some fields will be overwritten by k0smotron. K0smotron will set the following fields:

  • spec.k0sConfig.spec.api.externalAddress will be set to the value of spec.externalAddress if spec.externalAddress is set. If not, k0smotron will use load balancer IP or try to detect externalAddress out of nodes IP addresses.

  • spec.k0sConfig.spec.konnectivity.port will be set to the value of spec.service.konnectivityPort.
