An insight on CPU requests in Kubernetes
Jan 19, 2023
- CPU requests specify the amount of CPU a Pod will be allocated
- If there not enough resources on your cluster to satisfy the CPU requests the pod won’t be scheduled
- That means you should probably imagine the CPU requests as 100% of the CPU available to the pod
- Anything after the requests can either run at full speed or be throttled (if nodes are already saturated)
- Of course anything after the CPU limit (if specified) will be artificially throttled
- The beauty of Docker and Kubernetes is that you can slice the CPU power in uneven pieces instead of allocating 1 machine per application
