What are Kubernetes namespace limits and how do they work?

Kubernetes namespace limits are resource quotas that restrict the amount of resources a namespace can use. They help manage resources effectively.

Can you give me an example of how to set these limits?

Sure! You can set limits using a ResourceQuota object in YAML. For example:

apiVersion: v1
kind: ResourceQuota
metadata:
  name: my-quota
  namespace: my-namespace
spec:
  hard:
    requests.cpu: "2"
    requests.memory: "4Gi"
    limits.cpu: "4"
    limits.memory: "8Gi"

What happens if a namespace exceeds its limits?

If a namespace exceeds its resource limits, Kubernetes will prevent new pods from being scheduled until the usage is reduced.

Are there any best practices for setting these limits?

Yes, it's best to analyze your workloads, set realistic limits based on usage patterns, and regularly review and adjust them as needed.
