Golang: Get stack printed via logrus (useful for logging in syslog)

log.go

// Kata runtime example:
//  sudo journalctl -t kata-runtime -o json -f  | jq .MESSAGE | grep DEBUG --color
import "runtime/debug"

func stackLogger(logger logrus.Entry) {
        stack_bytes := debug.Stack()
        stack := string(stack_bytes)

        for _, l := range strings.Split(stack, "\n") {
                logger.Warnf("DEBUG -> %s", l)
        }
}
