docker cli swarm 包导入问题

Question

我试图在我自己的项目中使用docker/cli 客户端库来创建/管理堆栈。

但是，我在构建项目时遇到了问题。

---

代码如下：

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!")
}

我已经设置了一个最小的 go.mod：

module github.com/dev/test

go 1.16

---

当我运行go get;我收到以下错误：

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@9​​87654322@ repo 进行了更深入的研究，似乎该项目不使用 go 模块；而是使用较旧的vendor dir 方法。

我想知道如何编译该项目。 go get有没有办法自动引用导入的docker/cli项目的vendor目录下的包？

默认情况下，go 命令只会添加模块的最新标记版本，以解决缺少的依赖项。

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 包没有还存在。

您可以通过显式传递版本的提交哈希或分支名称来向go 命令询问依赖项的更新版本。例如，在我撰写此评论时，最新的提交是 2dcf70aafdc9ea55af3aaaeca440638cde0ecda6，因此您可以将该提交传递给 go get，并且从那时起它似乎可以正确构建：
