What are the differences between CoreDNS and kube-dns in Kubernetes?
CoreDNS is the default DNS service in Kubernetes, while kube-dns is the older version. CoreDNS is more flexible and extensible.
Can you explain how CoreDNS is more flexible?
CoreDNS uses a plugin architecture, allowing users to customize DNS resolution with various plugins, unlike kube-dns.
What are some common plugins used with CoreDNS?
Common plugins include 'forward' for forwarding queries, 'cache' for caching responses, and 'rewrite' for modifying DNS queries.
Is kube-dns still used in any Kubernetes setups?
While kube-dns is deprecated, some legacy systems may still use it, but it's recommended to migrate to CoreDNS for better support.
