golang 通过私有镜像地址加载生成镜像并且允许用户名和密码

可以通过以下步骤使用私有镜像地址加载生成镜像，并且允许用户名和密码：

在本地机器上安装 Docker 和 Go。
在私有镜像地址上创建一个账户，并获取该账户的用户名和密码。
在 Go 代码中使用 Docker API 创建一个 Docker 客户端，并设置私有镜像地址的认证信息。

import (
    "github.com/docker/docker/client"
    "golang.org/x/net/context"
    "github.com/docker/docker/api/types"
    "github.com/docker/docker/api/types/auth"
)

func main() {
    ctx := context.Background()
    cli, err := client.NewClientWithOpts(client.FromEnv, client.WithAPIVersionNegotiation())
    if err != nil {
        panic(err)
    }

    authConfig := auth.AuthConfig{
        Username: "your_username",
        Password: "your_password",
    }
    encodedAuth, err := json.Marshal(authConfig)
    if err != nil {
        panic(err)
    }

    _, err = cli.ImagePull(ctx, "private_registry/image_name", types.ImagePullOptions{
        RegistryAuth: base64.URLEncoding.EncodeToString(encodedAuth),
    })
    if err != nil {
        panic(err)
    }

    // build your image here
}

使用 Docker API 构建你的镜像。

import (
    "os"
    "github.com/docker/docker/api/types"
    "github.com/docker/docker/api/types/container"
    "github.com/docker/docker/api/types/mount"
    "github.com/docker/docker/api/types/network"
    "github.com/docker/docker/api/types/strslice"
)

func main() {
    // ...

    dockerfile, err := os.Open("Dockerfile")
    if err != nil {
        panic(err)
    }
    defer dockerfile.Close()

    buildContext, err := archive.TarWithOptions(".", &archive.TarOptions{})
    if err != nil {
        panic(err)
    }

    buildResponse, err := cli.ImageBuild(ctx, buildContext, types.ImageBuildOptions{
        Dockerfile: "Dockerfile",
        Tags:       []string{"private_registry/image_name"},
        Remove:     true,
    })
    if err != nil {
        panic(err)
    }

    // ...

    resp, err := cli.ContainerCreate(ctx, &container.Config{
        Image: "private_registry/image_name",
        Cmd:   strslice.StrSlice{"/bin/bash", "-c", "echo hello world"},
    }, &container.HostConfig{
        Mounts: []mount.Mount{
            {
                Type:   mount.TypeBind,
                Source: "/path/on/host",
                Target: "/path/in/container",
            },
        },
    }, &network.NetworkingConfig{}, "container_name")
    if err != nil {
        panic(err)
    }

    // ...
}
