Tengo un clúster K8 que se ejecuta en 2 hosts de VM, con los 6 nodos k8 y los 3 maestros divididos en ambos. Recientemente tuvimos un problema en el que uno de los servidores dejó de funcionar dejándome con solo un maestro y 3 nodos. Todos mis servicios siguen ejecutándose pero no puedo acceder a la API. Al observar el maestro restante, el contenedor del servidor API de Kube no aparece porque parece que no puede registrarse.
Los registros del contenedor de Api Server son los siguientes
