I want to use docker command inside image
Here is my Dockerfile
FROM ubuntu:16.04
USER root
RUN apt-get update -y && \
apt-get install -y curl && \
curl -fsSL get.docker.com -o get-docker.sh && \
sh get-docker.sh && \
usermod -aG docker daemon && \
curl -L https://github.com/docker/compose/releases/download/1.18.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose && \
chmod +x /usr/local/bin/docker-compose && \
service docker start && \
docker ps && \
docker-compose --version
But I got this error. How could I fix this?

docker in docker is usually just used for testing new docker versions…but even there it has side effects.
Details: http://jpetazzo.github.io/2015/09/03/do-not-use-docker-in-docker-for-ci/
depending on your use case, you probably should consider different approaches. you could:
just install the docker client and map the docker socket from outside in
map docker socket and docker binary from outside in
put your compose app into just a single docker file
provide your software as docker-stack-file

I try to use docker to run a docker compose to test my project.
So I want to build a image with docker compose.
I am not sure is it possible to use docker in side docker.

i would prefer to mount in your docker.sock into your docker or to use probably Vagrant to set up your defined lightweight docker compose environment.
