获取docker API引擎exec输出

我尝试从容器中运行一个命令我得到的输出，但我只到目前为止在RAW文本。 我需要能够得到与PHP输出，似乎我不能这样做，当它返回RAW文本。

这是我的Dockerfile：

FROM phusion/baseimage:0.9.19 CMD ["/sbin/my_init"] WORKDIR /root RUN sed -i "s/^exit 101$/exit 0/" /usr/sbin/policy-rc.d RUN apt-get update RUN DEBIAN_FRONTEND="noninteractive" apt-get install -y \ nginx \ php-fpm php-mysql php-gd php-curl php-cli php-mbstring php-dom unzip RUN service php7.0-fpm start EXPOSE 80 RUN apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* 

这里是我正在运行的curl请求：

 ## Create container curl --unix-socket /var/run/docker.sock -H "Content-Type: application/json" -d '{"Image":"test-container","Env":["VIRTUAL_HOST=test.domain.dev"]}' -X POST http:/v1.27/containers/create?name=test.domain.dev ## Start container curl --unix-socket /var/run/docker.sock -H "Content-Type: application/json" -X POST http:/v1.27/containers/test.domain.dev/start ## Create exec instance curl --unix-socket /var/run/docker.sock -H "Content-Type: application/json" -d '{ "AttachStdin":false,"AttachStdout":true,"AttachStderr":true, "Tty":false, "Cmd":["/bin/bash", "-c", "date"] }' -X POST http:/v1.27/containers/test.domain.dev/exec ## Start exec instance curl --unix-socket /var/run/docker.sock -H "Content-Type: application/json" -d '{ "Detach": false, "Tty": false }' -X POST http:/v1.27/exec/bcd34186a9a7360809cace3674fec03bd1c70c1c453be24ad058a03fa0b0e960/start // Sun Mar 26 23:23:53 UTC 2017 

docker info输出：

那么，有没有什么合适的方法来获得这个输出？ 谢谢你的帮助
