setting ports for container in docker for docker golang api

问题

我期待使用Docker Golang API来执行以下操作:

命令:docker run -t -i -p 8989:8080 "image-name" /bin/bash

我正在使用Golang SDK https://github.com/moby/moby/client 或者 https://godoc.org/github.com/moby/moby/client,我的Docker API版本是1.30(客户端和服务器都是)。

这是我正在使用的代码片段:

package main

import (
    "fmt"
    "github.com/docker/docker/client"
    "github.com/docker/docker/api/types"
    "github.com/docker/docker/api/types/container"
    "golang.org/x/net/context"
    "github.com/docker/go-connections/nat"
)

func check(err error) {
    if err != nil {
        panic(err)
    }
}

func main() {
    ctx := context.Background()
    cli, err := client.NewEnvClient()
    check(err)

    config := &container.Config{
        Image: "image-name",
        ExposedPorts: nat.PortSet{
            "8080/tcp": struct{}{},
        },
        Cmd: []string{"sh", "-c", "while true; do sleep always; done", "/bin/bash"},
    }

    hostConfig := &container.HostConfig{
        PortBindings: nat.PortMap{
            "8080/tcp": []nat.PortBinding{
                {
                    HostIP:   "0.0.0.0",
                    HostPort: "8989",
                },
            },
        },
    }

    resp, err := cli.ContainerCreate(ctx, config, hostConfig, nil, "")
    check(err)

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

编译这段代码后,我得到以下错误:

# command-line-arguments
src\main\createcontainer1.go:53: cannot use "github.com/docker/go-connections/nat".PortSet literal (type "github.com/docker/go-connections/nat".PortSet) as type "github.com/docker/docker/vendor/github.com/docker/go-connections/nat".PortSet in field value

src\main\createcontainer1.go:65: cannot use "github.com/docker/go-connections/nat".PortMap literal (type "github.com/docker/go-connections/nat".PortMap) as type "github.com/docker/docker/vendor/github.com/docker/go-connections/nat".PortMap in field value

如果有人知道问题出在哪里以及如何解决,请回答我。因为我是Docker的初学者。

英文:

I am looking forward to do something below like this using docker golang api

cmd : docker run -t -i -p 8989:8080 "image-name" /bin/bash

Also I am using golang sdk https://github.com/moby/moby/client or https://godoc.org/github.com/moby/moby/client and my docker api version is 1.30 (Client & Server both)

Here is the piece of code I am using

 package main

 import (
       "fmt"

       "github.com/docker/docker/client"
       "github.com/docker/docker/api/types"
       "github.com/docker/docker/api/types/container"
       "golang.org/x/net/context"
       "github.com/docker/go-connections/nat"
    //"github.com/docker/docker/vendor/github.com/docker/go-connections/nat"
)

func check(err error) {
   if err != nil {
       panic(err)
   }
}


func main(){
    ctx := context.Background()
cli, err := client.NewEnvClient()
check(err)


config := &container.Config{
Image : image-name,
ExposedPorts: nat.PortSet{
    "8080/tcp": struct{}{},
},
Cmd : [] string {"sh","-c","while true; do sleep always; done","/bin/bash"},
}

host_config := &container.HostConfig{
     PortBindings: nat.PortMap{
     "8080/tcp": []nat.PortBinding{
         {
             HostIP: "0.0.0.0",
             HostPort: "8989",
         },
      },
   },
}


  resp, err := cli.ContainerCreate(ctx,config,host_config, nil,"")
  check(err)


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


}

After Compiling this code I get the following error

# command-line-arguments
src\main\createcontainer1.go:53: cannot use "github.com/docker/go-connections/nat".PortSet literal (type "github.com/docker/go-connections/nat".PortSet) as type "github.com/docker/docker/vendor/github.com/docker/go-connections/nat".PortSet in field value

src\main\createcontainer1.go:65: cannot use "github.com/docker/go-connections/nat".PortMap literal (type "github.com/docker/go-connections/nat".PortMap) as type "github.com/docker/docker/vendor/github.com/docker/go-connections/nat".PortMap in field value

If somebody knows what could be the problem and how to fix it.
Please answer to it as I am beginner with docker.

这是一个关于vendor/工作方式的Golang问题。

删除嵌套的vendor目录:

rm -rf vendor/github.com/docker/docker/vendor

如果你正在使用glide,在安装依赖时应该使用glide install -v

更多详情,请查看这个已报告的问题

英文:

This is a Golang issue with how vendor/ works.

Remove the nested vendor directory:

rm -rf vendor/github.com/docker/docker/vendor

If you are using glide, you should use glide install -v when installing the dependency.

For more details, check this reported issue

我的OSX解决方案:

mv /Users/<user>/go/src/github.com/docker/docker/vendor/github.com/docker/go-connections/{nat,nat.old}
英文:

My solution for OSX:

mv /Users/&lt;user&gt;/go/src/github.com/docker/docker/vendor/github.com/docker/go-connections/{nat,nat.old}
