Calculate the total CPU limit currently used by the existing pods:

• Each of the three existing pods has a CPU limit of 500m, which is equal to 0.5 CPU (since 1000m = 1 CPU).

• Total CPU limit used by existing pods = 3 pods * 0.5 CPU/pod = 1.5 CPUs.

Determine the remaining CPU capacity on the node based on the limits:

• The node has a total of 4 CPUs available.

• Remaining CPU capacity for new pods (based on limits) = Total node CPU - CPU limit used by existing pods

• Remaining CPU capacity = 4 CPUs - 1.5 CPUs = 2.5 CPUs.

Calculate how many additional pods with the given configuration can fit within the remaining CPU limit:

• Each additional pod has a CPU limit of 1 CPU.

• Maximum number of additional pods = Remaining CPU capacity / CPU limit per additional pod

• Maximum number of additional pods = 2.5 CPUs / 1 CPU/pod = 2.5 pods.

Since you can't have a fraction of a pod, the maximum whole number of additional pods that can be scheduled without exceeding the CPU limits is 2.
