Running a host docker command inside a denkins docker container

Question

I have a docker container in which jenkins work. I want another container running inside this container, so outside this container.

I tried to start my jenkins controller using

docker run -v /var/run/docker.sock:/var/run/docker.sock  -v $(which docker):/bin/docker

(As written here: https://jpetazzo.imtqy.com/2015/09/03/do-not-use-docker-in-docker-for-ci/ )

But when inside my container I try to run the Docker command, I have a typical message

 FATA[0000] Get http://%2Fvar%2Frun%2Fdocker.sock/v1.18/containers/json: dial unix /var/run/docker.sock: 
connect: permission denied. Are you trying to connect to a TLS-enabled daemon without TLS? 

And there is no need to run the docker command inside this container.

I tried with and without --privileged = true, it still doesn't work.

If you have any ideas!
