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：

  1. package main
  3. import (
  4.     "fmt"
  5.     "github.com/docker/docker/client"
  6.     "github.com/docker/docker/api/types"
  7.     "github.com/docker/docker/api/types/container"
  8.     "golang.org/x/net/context"
  9.     "github.com/docker/go-connections/nat"
  10. )
  12. func check(err error) {
  13.     if err != nil {
  14.         panic(err)
  15.     }
  16. }
  18. func main() {
  19.     ctx := context.Background()
  20.     cli, err := client.NewEnvClient()
  21.     check(err)
  23.     config := &container.Config{
  24.         Image: "image-name",
  25.         ExposedPorts: nat.PortSet{
  26.             "8080/tcp": struct{}{},
  27.         },
  28.         Cmd: []string{"sh", "-c", "while true; do sleep always; done", "/bin/bash"},
  29.     }
  31.     hostConfig := &container.HostConfig{
  32.         PortBindings: nat.PortMap{
  33.             "8080/tcp": []nat.PortBinding{
  34.                 {
  35.                     HostIP:   "0.0.0.0",
  36.                     HostPort: "8989",
  37.                 },
  38.             },
  39.         },
  40.     }
  42.     resp, err := cli.ContainerCreate(ctx, config, hostConfig, nil, "")
  43.     check(err)
  45.     if err := cli.ContainerStart(ctx, resp.ID, types.ContainerStartOptions{}); err != nil {
  46.         panic(err)
  47.     }
  48. }

编译这段代码后，我得到以下错误：

  1. # command-line-arguments
  2. 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
  4. 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

  1.  package main
  3.  import (
  4.        "fmt"
  6.        "github.com/docker/docker/client"
  7.        "github.com/docker/docker/api/types"
  8.        "github.com/docker/docker/api/types/container"
  9.        "golang.org/x/net/context"
  10.        "github.com/docker/go-connections/nat"
  11.     //"github.com/docker/docker/vendor/github.com/docker/go-connections/nat"
  12. )
  14. func check(err error) {
  15.    if err != nil {
  16.        panic(err)
  17.    }
  18. }
  21. func main(){
  22.     ctx := context.Background()
  23. cli, err := client.NewEnvClient()
  24. check(err)
  27. config := &container.Config{
  28. Image : image-name,
  29. ExposedPorts: nat.PortSet{
  30.     "8080/tcp": struct{}{},
  31. },
  32. Cmd : [] string {"sh","-c","while true; do sleep always; done","/bin/bash"},
  33. }
  35. host_config := &container.HostConfig{
  36.      PortBindings: nat.PortMap{
  37.      "8080/tcp": []nat.PortBinding{
  38.          {
  39.              HostIP: "0.0.0.0",
  40.              HostPort: "8989",
  41.          },
  42.       },
  43.    },
  44. }
  47.   resp, err := cli.ContainerCreate(ctx,config,host_config, nil,"")
  48.   check(err)
  51.   if err := cli.ContainerStart(ctx, resp.ID, types.ContainerStartOptions{}); 
  52.       err != nil {
  53.         panic(err)
  54.   }
  57. }

After Compiling this code I get the following error

  1. # command-line-arguments
  2. 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
  4. 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：

  1. 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:

  1. 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：

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

My solution for OSX:

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