golang docker client通过ssh调用远程主机的接口

        golang通过tcp方式连接调用远程主机docker的接口

        可参考：https://mp.csdn.net/mp_blog/creation/editor/126315928

        本文主要是用Go通过ssh方式连接到远程主机，调用docker接口

前提

  docker api通过ssh方式调用远程主机的接口，前提是通过免密登陆

    免密登陆可参考：https://mp.csdn.net/mp_blog/creation/editor/126679013

1. 初始化Docker Client

import(
  "net/http"
 
  "github.com/docker/cli/cli/connhelper"
  "github.com/docker/docker/client"
)
 
func getClientBySsh() (cli *client.Client, err error) {
  //user为远程主机的用户名，一般是root，ip是远程主机的具体ip地址
  helper, _ := connhelper.GetConnectionHelper("ssh://user@ip:22")
  httpClient := &http.Client{
    Transport: &http.Transport{
      DialContext: helper.Dialer,
    },
  }
 
  cli, err = client.NewClientWithOpts(
    client.WithHTTPClient(httpClient),
    client.WithHost(helper.Host),
    client.WithDialContext(helper.Dialer),
    client.WithVersion("1.40"),  //指定当前docker部署的版本
  )
 
  return
}

2. 调用docker api去操作容器

相关操作可参考官网：https://docs.docker.com/engine/api/sdk/examples/

官方通过client.FromEnv方式初始化，适用于本级docker client初始化，不适合远程调用
