What Happened

Containers were being killed because they exceeded their resource limits for memory and CPU.

Diagnosis Steps

1Used kubectl describe pod to find the resource limits and found that the limits were too low for the workload.
2Analyzed container logs and found frequent OOMKilled events.

Root Cause

The resource limits set for the container were too low, causing the container to be terminated when it exceeded the limit.

Fix/Workaround

• Increased the resource limits for the affected containers.
• Re-applied the pod configurations and monitored for stability.

Lessons Learned

Resource limits should be set based on actual workload requirements.
