Using NodeLocal DNSCache

Challenges

When the number of DNS requests in a cluster increases, the load of CoreDNS increases and the following issues may occur:

  • Increased delay: CoreDNS needs to process more requests, which may slow down the DNS query and affect service performance.
  • Increased resource usage: To ensure DNS performance, CoreDNS requires higher specifications.

Solution

NodeLocal DNSCache can improve the stability and performance of service discovery.

For details about NodeLocal DNSCache and how to deploy it in a cluster, see Using NodeLocal DNSCache to Improve DNS Performance.
