See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1 . Configure CoreDNS with Namespace-Specific DNS:
- In the CoreDNS ConfigMap, configure the 'kubernetes' plugin to restrict DNS resolution based on namespaces.

2. Use Network Policies for Cross-Namespace Communication: - If you need pods in one namespace to communicate with services in another namespace, use network policies to explicitly allow the communication.
