我能够建立一个Dockerfile像
Docker build -t deepak/ruby。
但是对于一个Dockerfile,它不叫Dockerfile
# DOCKER-VERSION 0.4.8
FROM deepak/ruby
MAINTAINER Deepak Kannan "deepak@example.com"
RUN ./bin/rails s
我们假设它叫Dockerfile.app
我们用它来建造
Dockerfile.app . docker build -t deepak/app
然后得到错误
Uploading context 0 bytes
Error build: EOF
EOF
对我来说,一旦我把整个路径放在文件选项中,它就起作用了:

这对我来说是失败的:

dockerfeed试试。它使用docker特性通过stdin构建上下文。我写这个剧本就是为了解决你的问题。
用一个不同的Dockerfile替换一个Dockerfile,你可以这样做:
dockerfeed -d Dockerfile.app . | docker build -t deepak/ruby -
瞧。Dockerfeed和docker build做的是一样的。它将源文件与Dockerfile打包在一起,但允许您用所需的Dockerfile替换旧的Dockerfile。在此过程中不会创建任何文件,也不会更改源。生成的tar归档文件通过管道传输到docker, docker又将其发送到docker守护进程。
更新:
在以前没有-f开关的时候,这是一个有效的答案。在docker 1.5版中引入了这个选项。现在你可以像这样构建一个不同的Dockerfile:
docker build -f other-Dockerfile .
