如何在dockerfile from子句中包含凭据

Question

我是Docker的新手。我克隆了GitHub项目，并试图通过运行来创建映像

docker build -t imagename .

但它给出了一个错误：

username@LAPTOP-MMMMBU:~/myfolder/test$ docker build -t newimage .

如果您询问如何向提取基本映像的docker注册表进行身份验证，您可以运行docker login registry.abcd.org，并在提示时输入用户名和密码。然后，您的后续构建命令将能够提取图像。

docker login [OPTIONS] [SERVER]
