Curl 获取docker API引擎exec输出

我试图从容器中运行的命令中获取输出，但到目前为止，我只从原始文本中获取它。我需要能够得到PHP的输出，似乎我不能这样做，当它返回原始文本

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/*

下面是我正在运行的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

那么，有没有合适的方法来获得这个输出呢？感谢您的帮助

在创建exec实例时，我被设置为“AttachstOut”为true，而“Tty”为true。 在request start exec中，我被设置为true中的“Tty”

这向我显示了tty中的值，但我无法从应用程序中捕获它

# Create the exec
#
EXEC_CREATE=`curl --silent --unix-socket /var/run/docker.sock "http:/containers/${CONTAINER_NAME}/exec" -XPOST \
  -H "Content-Type: application/json" \
  -d '{
    "AttachStdout": true,
    "Tty": true,
    "Cmd": [ "ruby", "-e", "5.times { puts :hi; sleep 1 }"]
  }'
`
echo $EXEC_CREATE | jq '.'

# Run the exec
#
EXEC_ID=$(echo $EXEC_CREATE | jq -r '.Id')
curl --silent --unix-socket /var/run/docker.sock "http:/exec/${EXEC_ID}/start" -XPOST \
  -H "Content-Type: application/json" \
  -d '{
    "Detach": false,
    "Tty": true
  }'

有人找到了答案吗？
