Step-by-Step Solution
Solution:
Step 1: Identify the problem with pod IPs
Pods get new IPs on restart, so direct IP communication is unstable.Step 2: Use Kubernetes Service for stability
Services provide a stable DNS name and load balancing to reach pods regardless of IP changes.Step 3: Evaluate other options
Static IPs for pods are not practical; host networking breaks isolation; direct IP use is unreliable.Final Answer:
Use a Kubernetes Service to provide a stable DNS name and load balancing -> Option AQuick Check:
Service = stable pod communication [OK]
Quick Trick: Use services for stable pod communication despite IP changes [OK]
Common Mistakes:
- Hardcoding pod IPs in configs
- Trying to assign static IPs to pods
- Using host networking unnecessarily
