go - Docker API 调用返回 "server gave HTTP response to HTTPS client"

Question

我有以下代码，调用 API 返回错误如下，我还在下面粘贴了 Docker Daemon 命令。我已经尝试了 HTTP/HTTPS/TCP 的一些组合，有/没有 TLS。

我哪里错了？

“ panic :尝试连接时发生错误:获取 https://172.28.8.212:2375/v1.24/containers/json?limit=0:http:服务器向 HTTPS 客户端提供 HTTP 响应"

func main() {
    var headers map[string]string

    tr := &http.Transport{
        TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
    }

    cl := &http.Client{Timeout: time.Minute}

    cli, err := client.NewClient("tcp://172.28.8.212:2375", "1.24", cl, headers)
    if err != nil {
        panic(err)
    }

    containers, err := cli.ContainerList(context.Background(), types.ContainerListOptions{})
    if err != nil {
        panic(err)
    }

    for _, container := range containers {
        fmt.Printf("%s %s\n", container.ID[:10], container.Image)
    }
}

我的Docker Daemon启动如下

[Unit]
Description = Docker Service Daemon
[Service]
ExecStart=/usr/bin/docker daemon -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock --cluster-store=consul://172.28.8.211:8500

func main() {
    var headers map[string]string

    tr := &http.Transport{} <---- Note the difference here. 

    tr.Dial = func(proto, addr string) (net.Conn, error) {
        fmt.Println("Dial called")
        conn, err := net.DialTimeout(proto, addr, time.Minute)
        if err != nil {
            fmt.Println("There was  an err", err)
        }
        return conn, err
    }

    cl := &http.Client{Transport: tr}
    cli, err := client.NewClient("http://x.y.z.w:2376", "1.24", cl, headers)
    if err != nil {
        panic(err)
    }

    containers, err := cli.ContainerList(context.Background(), types.ContainerListOptions{})
    if err != nil {
        panic(err)
    }

    for _, container := range containers {
        fmt.Printf("%s %s\n", container.ID[:10], container.Image)
    }
}
