Pod Isolation Introduction

Pod Isolation enables immediate traffic cutoff to malfunctioning Pods while maintaining their operational state. This feature:

  • Prevents request failures from defective Pods
  • Maintains service availability during troubleshooting
  • Allows seamless reintegration after repair

Core purpose: Ensure service continuity by dynamically managing endpoint participation

Limitations

  • State Constraints Only affects Running Pods, excludes Completed/CrashLoopBackOff

  • Version Compatibility Legacy services require label updates (asm.cpaas.io/msselector)

  • Conflict Scenarios Disabled during canary releases and horizontal scaling events

  • Persistence Isolation resets on pod restart or scale-down operations
