The ./data/ directory is used to store all status information of kube-install, including configuration information of all kubernetes clusters. You can share the ./data/ directory through file storage, so as to realize active and standby or load balancing cluster.
You can use software such as Keepalived or Heartbeat to detect and switch between active and standby.
You can use LVS, Nginx or Haproxy software to achieve load balancing and cluster switching.
