docker - 我尝试构建一个使用 alpine linux 图像并打印 "Hello StackOverflow!"的简单图像。这里的问题是什么？

Question

Windows PowerShell:

PS C:\Users\Administrator> docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

alpine/git          latest              a8b6c5c0eb62        2 weeks ago         28.4MB

PS C:\Users\Administrator> docker build C:\dfiles

dockerfile存放路径:C:\dfiles

我的 Dockerfile.txt 中的代码:

FROM alpine
CMD ["echo", "Hello StackOverflow!"]

简单

仅使用 Dockerfile 而不使用 Dockerfile.txt
