Golang - Incorrect CPU Numbers of GOMAXPROCS in Docker

The runtime.GOMAXPROCS(??) will read the host machine's CPU numbers instead of container's (--cpus=??). We can use UBER's automaxprocs to solve it.

go get -u go.uber.org/automaxprocs

import _ "go.uber.org/automaxprocs"

func main() {
  // Your application logic here.
}
