docker cli swarm包导入问题

Question

我试图在自己的项目中使用docker/cli客户端库来创建/管理堆栈。

然而，我在建设这个项目时遇到了一些问题。

---

下面的代码：

package main
import (
"fmt"
"log"
"github.com/docker/cli/cli/command"
"github.com/docker/cli/cli/command/stack"
"github.com/docker/cli/cli/flags"
)
func main() {
cli, err := command.NewDockerCli(command.WithStandardStreams())
if err != nil {
log.Fatal(err)
}
cli.Initialize(flags.NewClientOptions())
cmd := stack.NewStackCommand(cli)
cmd.SetArgs([]string{"deploy", "--compose-file", "docker-compose.yml", "test"})
err = cmd.Execute()
if err != nil {
log.Fatal(err)
}
fmt.Println("success!")
}

我已经设置了最小go.mod:

module github.com/dev/test
go 1.16

---

当我运行go get时；我得到以下错误：

github.com/dev/test imports
github.com/docker/cli/cli/command/stack imports
github.com/docker/cli/cli/command/service imports
github.com/docker/swarmkit/api/defaults: cannot find module providing package github.com/docker/swarmkit/api/defaults
github.com/dev/test imports
github.com/docker/cli/cli/command/stack imports
github.com/docker/cli/cli/command/service imports
github.com/docker/swarmkit/api/genericresource: cannot find module providing package github.com/docker/swarmkit/api/genericresource
github.com/dev/test imports
github.com/docker/cli/cli/command/stack imports
github.com/docker/cli/cli/command/service imports
github.com/docker/swarmkit/api imports
google.golang.org/grpc/transport: cannot find module providing package google.golang.org/grpc/transport

我对docker/cli repo进行了更深入的研究，发现该项目似乎不使用go模块；而是使用较旧的CCD_ 2 dir方法。

我想知道如何才能编译这个项目。go get是否有方法自动引用导入的docker/cli项目的vendor目录中的包？

默认情况下，go命令将只添加模块的最新标记版本，以解决丢失的依赖项。

根据https://github.com/docker/swarmkit/tags，github.com/docker/swarmkit的最新(也是唯一(标记版本是v1.12.0，早在2016年(！(，当时api/defaults和api/genericresource包还不存在。

您可以通过显式传递依赖项的提交哈希或分支名称，向go命令请求一个比标记的版本更新的依赖项。例如，当我写这条评论时，最新的提交是2dcf70aafdc9ea55af3aaaeca440638cde0ecda6，所以您可以将该提交传递给go get，从那时起，它似乎可以正确构建：
