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.
