Do we have some Api in Kubernetes to know if we have enough resources to run deployment of pods before sending the request on prem envirenment?

the reason I need it is because I want to run a pod from another pod and I want to make sure I have enough of resources.

To get information about CPU(cores), CPU%, memory, and memory% usage of your nodes, you can run kubectl top nodes command.

For example:

1 kubectl top node --use-protocol-buffers
2 NAME           CPU(cores)   CPU%   MEMORY(bytes)   MEMORY%
3 example-node   500m         50%    573Mi           20%
  • CPU(cores) - 500m means 500 millicpu. 1000m is equal to 1 CPU, hence 500m means 50% of 1 CPU.
  • CPU% - Total CPU usage percentage of that node.
  • Memory - Memory being used by that node.
  • Memory% - Total memory usage percentage of that node.
