如何为私有注册登录凭据创建“RegistryAuth”

Question

我使用以下命令创建了一个私有注册表：

docker run -d -p 5000:5000 --restart=always --name registry -e REGISTRY_STORAGE_DELETE_ENABLED=true registry:2

我正在尝试使用 Golang docker 客户端 API -> ImagePush将图像推送到此注册表

func (cli *Client) ImagePush(ctx context.Context, image string, options types.ImagePushOptions) (io.ReadCloser, error)

当我放大ImagePushOptions我看到该结构是

type ImagePullOptions struct {
    # All bool
    RegistryAuth string // RegistryAuth is the base64 encoded credentials for the registry
    PrivilegeFunc RequestPrivilegeFunc
}

AnyIdea 如何创建 RegistryAuth 字符串

我尝试执行以下操作：

type AuthArgs struct {
    Username string json:"username"
    Password string json:"password"
    Email string json:"email"
    ServerAddress string json:"serveraddress"
}

func() {
    m := AuthArgs{"docker", "docker", "", "localhost:5000"}
    b, err := json.Marshal(m)

    fmt.Println(string(b))
    encodeStr := base64.StdEncoding.EncodeToString(b)

    refStr := "localhost:5000/" + image + ":" + tag
    fmt.Println(refStr)
    resp, err := cli.ImagePush(ctx, refStr, types.ImagePushOptions{RegistryAuth: encodeStr })

我被困了 3 天，任何帮助都会很棒

Answer 1

auth := types.AuthConfig{
    Username: cfg.User,
    Password: cfg.Passwd,
}
authBytes, _ := json.Marshal(auth)
authBase64 := base64.URLEncoding.EncodeToString(authBytes)
