I am trying to access interactive shell of a running docker container using Golang. Here is what I tried.
package main
import (
"fmt"
"log"
"os"
"os/exec"
)
func main() {
prg := "docker"
arg1 := "exec"
arg2 := "-ti"
arg3 := "df43f9a0d5c4"
arg4 := "bash"
cmd := exec.Command(prg, arg1, arg2, arg3, arg4)
cmd.Stdout = os.Stdout
cmd.Stderr = os.Stderr
fmt.Printf("[Command] %s\n", cmd.String())
log.Printf("Running command and waiting for it to finish...")
err := cmd.Run()
if err != nil {
log.Fatal(err)
}
fmt.Printf("Command finished with error %s\n", cmd.String())
}
AND here is output with error:
> [Command] /usr/bin/docker exec -ti df43f9a0d5c4 bash 2022/07/28
> 19:21:02 Running command and waiting for it to finish... the input
> device is not a TTY 2022/07/28 19:21:02 exit status 1 exit status 1
Note: Interactive shell of running docker container works fine when executing this command directly on the shell
"github.com/docker/docker/client"API client, instead of trying to shell todocker exec? If Docker weren't involved, how would you perform this task to run some command inside some other process? - David Maze
