《自己动手写docker》之namespace部门实验

动手写一遍，印象不一样！

package main

import (
    "log"
    "os"
    "os/exec"
    "syscall"
)

func main() {
    cmd := exec.Command("sh")
    cmd.SysProcAttr = &syscall.SysProcAttr{}
    cmd.SysProcAttr.Cloneflags = syscall.CLONE_NEWNS | syscall.CLONE_NEWUTS | syscall.CLONE_NEWPID | syscall.CLONE_NEWIPC | syscall.CLONE_NEWNET
    cmd.SysProcAttr.Credential = &syscall.Credential{Uid: uint32(1), Gid: uint32(1)}
    cmd.Stdin = os.Stdin
    cmd.Stdout = os.Stdout
    cmd.Stderr = os.Stderr

    if err := cmd.Run(); err != nil {
        log.Fatal(err)
    }
    os.Exit(-1)
}
