What are HPA limits in Kubernetes?
HPA stands for Horizontal Pod Autoscaler. It automatically scales the number of pods in a deployment based on observed CPU utilization or other select metrics.
How do I set HPA limits for my application?
You can set HPA limits using the kubectl autoscale
command, specifying the deployment name, minimum and maximum replicas, and the target CPU utilization.
What happens if the HPA limits are reached?
If the HPA reaches its maximum limit, it won't scale up any further, even if the resource usage continues to increase. You'll need to manually adjust the limits.
Can I use custom metrics for HPA?
Yes, you can use custom metrics by integrating with the Kubernetes Metrics API or using external metrics providers.
