How to Spin up docker container & run some command via golang script?
问题
我计划自动化创建容器并在其中运行一些命令。但是我遇到了以下错误：
docker run -it alpine sh ls
我得到的错误是：
docker错误：输入设备不是TTY。
所以我去掉了交互部分，运行了以下命令：
docker run -t alpine sh ls
我没有得到shell，但是docker正在运行。
我在golang的os.exec包中运行了上述docker命令。
package main
import (
"fmt"
"os"
"os/exec"
"sync"
)
func main() {
var wg sync.WaitGroup
wg.Add(1)
go func() {
defer wg.Done()
cmd := exec.Command("docker", "run","-it","alpine","sh","ls")
cmd.Stdout = os.Stdout
cmd.Stderr = os.Stderr
cmd.Run()
// log.Println(cmd.Run())
}()
wg.Wait()
}
我的意图是在启动docker后运行多个shell脚本。
如果有任何帮助，将不胜感激。谢谢。

I am planning to automate spinning up container and run some commands on it.
But I get the below error
docker run -it alpine sh ls
Error I get is
docker error : the input device is not a TTY.
So I removed interactive part and ran
docker run -t alpine sh ls
I don't get the shell but docker is spinning
I run above docker commands in golangs os.exec package.
package main
import (
"fmt"
"os"
"os/exec"
"sync"
)
func main() {
var wg sync.WaitGroup
wg.Add(1)
go func() {
defer wg.Done()
cmd := exec.Command("docker", "run","-it","alpine","sh","ls")
cmd.Stdout = os.Stdout
cmd.Stderr = os.Stderr
cmd.Run()
// log.Println(cmd.Run())
}()
}()
wg.Wait()
}
My intention is to run multiple shell scripts after spinning up the docker.
Any help would be appreciated. Thanks

一个可以探索的途径是使用官方的包moby/moby integration-cli和moby/moby integration-cli/cli with cli.go。
func Docker(cmd icmd.Cmd, cmdOperators ...CmdOperator) *icmd函数用于运行docker命令，带有参数。
例如，对于docker run命令的示例：
cli.Docker(cli.Args("run", "--name", name, "--rm", "busybox", "sh", "-c", "sleep 30; echo hi"))
英文:
One avenue to explore is the official packages moby/moby integration-cli and moby/moby integration-cli/cli with cli.go.
The func Docker(cmd icmd.Cmd, cmdOperators ...CmdOperator) *icmd is made to run a docker command, with parameters.
cli.Docker(cli.Args("run", "--name", name, "--rm", "busybox", "sh", "-c", "sleep 30; echo hi"))
