我正在尝试官方链接中提到

构建。

但是我无法获得文件中的内容：示例请求：

POST /v1.24/build HTTP/1.1
{{ TAR STREAM }}

有几件事使我感到困惑，

1）在哪里提到的？

2）“归档文件必须在归档文件的根目录中包含一个构建指令文件，通常称为Dockerfile。” 来自docker docs的此声明，这里的困惑

是？

3）是什么？

回答：

最后，能够。

样本Dockerfile：

# cat Dockerfile FROM ubuntu:14.04 RUN mkdir demo RUN apt-get update RUN apt-get -y install vim

创建一个包含您的Dockerfile的tar文件。

# tar -cvf Dockerfile.tar.gz Dockerfile

执行以下API，有关更多选项，请参考此。

# curl -v -X POST -H "Content-Type:application/tar" --data-binary '@Dockerfile.tar.gz' http://127.0.0.1:5000/build?t=build_test
