NumCPU()
How many cpu's does my pod see?
kubectl exec -it $pod -- /bin/bash apt-get update apt-get install golang
tmp.go
package main
import "fmt"
import "runtime"
func main() {
var i interface{} = runtime.NumCPU()
fmt.Printf("%v\n", i)
fmt.Println("hello world")
}
$ go run tmp.go 8 hello world
The answer is 8 , same as what I see if I look in /proc/cpuinfo in the pod.
