How to pivot bootstrapped controlplane

[sbskas]

Following the bootstraping, instruction for accessing bootstrapped cluster are missing. How does one access the sidero-metadata server and the sidero-controller-manager from the booted machine ?

There are 3 services :

• 9091 : metadaservice
• 8081 : retrieval of images using http protocol
• 69 : tftp retrieval

On the bootstrap server, all services are colocated to the same IP (a.k.a. PUBLIC_IP). On the cluster, a wild guess would be to have all services on the same IP in the same way. Public would be a loadbalancer service with 3 ports defined.

For this, one needs to activate the apiserver featureGate MixedProtocolLBService=true which is supported on k8s 1.20+.

Another way, would be to consume 3 loadbalancer service, one for each service.

In either case, documentation is missing the final detail to complete the bootstrap server.
