AI Technical Summary
In Kubernetes cluster federation, the parsing cluster acts as a single point of failure, causing cross-cluster parsing interruptions, resulting in long periods of abnormality and slow recovery.
A primary-backup DNS cluster architecture is adopted. The domain name resolution rules of the primary DNS cluster are deleted by the downgrade command, the DNS resolution rules of the backup DNS cluster are generated by the upgrade command, and the switch command is sent to switch the backup DNS cluster to the primary DNS cluster, thereby achieving high availability.
When the primary DNS cluster fails, the backup DNS cluster is quickly switched to become the primary cluster, reducing the time of cross-cluster DNS interruption and ensuring the continuity and high availability of the DNS service.
