I try to get the output from a command Im running inside a container, but I only get it in RAW text so far. I need to be able to get the output with PHP, seems like I cant do that when it returns in RAW text.
Here is my 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/*
And here is the curl requests Im running:
## 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

So, is there any proper way to get this output? Thanks for any help
I am set "AttachStdout" in true and "Tty" in true, when create exec instance. In the request start exec i am set "Tty" in true.
This shows me the values in the tty but I can't capture it from an application.
# 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
}'
