What are Kubernetes pod limits and how do they work?

Kubernetes pod limits are constraints that define the maximum resources (CPU and memory) a pod can use. They help manage resource allocation and ensure that no single pod can consume all the resources of a node.

How do I set these limits for my pods?

You can set resource limits in the pod specification under the resources field. For example:

resources:
  limits:
    memory: "512Mi"
    cpu: "500m"

What happens if a pod exceeds its limits?

If a pod exceeds its memory limit, it may be terminated by the Kubernetes system. For CPU, it will be throttled, meaning it will be limited in how much CPU it can use.

Can I set different limits for different containers in the same pod?

Yes, you can set different resource limits for each container within the same pod by specifying the resources field for each container individually.
