He actualizado el clúster de Kubernets (base de datos de 3 servidores maestros, 3 etcd) de 1.18a v1.19.13y ETCD a 3.4.13. Dado que los servidores API no son estables, siga cambiando de servidor etcd diferente, debido a que este clúster no funciona correctamente. estos clústeres se ejecutan en CentOS Steam 8. Este clúster funcionó antes de la actualización, solo después de la actualización vi este problema.
¿Alguna ayuda para resolver este problema? ¿Hay algún problema con esta versión?
