如何使用cmd创建dockerfile的docker镜像

Question

我有docker文件的样本代码，我从github。我想创建该文件的docker映像，并将其推送到azure容器存储库。我怎么能那样做呢?

当我运行这个命令时，我得到以下错误:

=> ERROR [internal] load metadata for mcr.microsoft.com/windows:1809                                              1.1s
=> CANCELED [internal] load metadata for mcr.microsoft.com/dotnet/framework/sdk:4.8                               1.1s

码头工人文件:

FROM mcr.microsoft.com/dotnet/framework/sdk:4.8 AS build
ARG CallSignalingPort=9441
ARG CallSignalingPort2=9442
ARG InstanceInternalPort=8445

RUN choco install openssl.light -y
EXPOSE $InstanceInternalPort
EXPOSE $CallSignalingPort
EXPOSE $CallSignalingPort2
ENTRYPOINT [ "entrypoint.cmd" ]

这是我从样本代码中得到的docker文件。我想要这个docker文件的docker镜像。请帮助我们如何创建docker文件?

Answer 1

1。要从docker文件构建docker镜像，使用:docker build .您可以使用-t参数用您想要的名称标记图像，否则它将采用一些随机名称。此外，(点)表示dockerfile的位置，假设dockerfile与命令提示符的pwd位于同一位置。更多信息请参考https://docs.docker.com/engine/reference/commandline/build/

2。要在azure中上传docker映像，您可以按照这里的说明:https://learn.microsoft.com/en-us/azure/container-registry/container-registry-get-started-docker-cli?tabs=azure-cli
