docker - 为什么我无法为 docker 获取 go sdk？

Question

我正在尝试运行 docker go SDK 示例文件。我对 Go 语言很陌生；我不确定如何在 docker SDK API 代码下运行。但是我以某种方式尝试过；请帮我解决以下错误。

当我尝试运行此 go run example-ps.go

example-ps.go - 内容如下

package main

import (
  "io"
  "os"

  "github.com/docker/docker/client"
  "github.com/docker/docker/api/types"
  "github.com/docker/docker/api/types/container"
  "golang.org/x/net/context"
)

func main() {
  ctx := context.Background()
  cli, err := client.NewEnvClient()
  if err != nil {
    panic(err)
  }

  _, err = cli.ImagePull(ctx, "docker.io/library/alpine", types.ImagePullOptions{})
  if err != nil {
    panic(err)
  }

  resp, err := cli.ContainerCreate(ctx, &container.Config{
    Image: "alpine",
    Cmd:   []string{"echo", "hello world"},
  }, nil, nil, "")
  if err != nil {
    panic(err)
  }

  if err := cli.ContainerStart(ctx, resp.ID, types.ContainerStartOptions{}); err != nil {
    panic(err)
  }

  if _, err = cli.ContainerWait(ctx, resp.ID); err != nil {
    panic(err)
  }

  out, err := cli.ContainerLogs(ctx, resp.ID, types.ContainerLogsOptions{ShowStdout: true})
  if err != nil {
    panic(err)
  }

  io.Copy(os.Stdout, out)
}

我遇到了以下错误。如何导入这些库文件？

如果您正确安装了 golang，只需在您的 golang 代码所在的目录中发出此命令

go get -v -t ./...

这将安装上游库......然后你可以编译你的代码......详情问题

go help packages

简而言之，./... 将安装在任何 go 文件的 import 中提到的所有包 [并递归地安装其上游包等]你当前的目录

如果您曾花费数天时间为任何其他语言手动安装上游库，您会明白这真的是多么救命稻草……是的，我在看你 c、c++、java，尤其是 python，它具有最粗糙的最不相交的库导入 machination 咒语炼金术
