Most engineers miss one critical configuration detail.
It crashes everything, not just one service.
Your cluster is one missing limit away from total failure.
A single pod consuming unlimited memory can bring down your entire system.
Then your databases go offline.
Your API stops responding.
Everything stops.
The fix is simple.
Set resource limits on every container.
Memory limits.
CPU limits.
They act as guardrails.
One runaway process can’t drag others down with it.
Check your deployments right now.
Search for containers without limits defined.
You’ll probably find them.
Add those limits today.
Your cluster will stay stable when things go wrong.
This one change prevents catastrophic outages.
