Running Docker inside Docker container: Cannot connect to the Docker daemon

Question

I created a Dockerfile to run Docker inside Docker:

    FROM ubuntu:16.04
RUN apt-get update && \\
    apt-get install -y \\
    apt-transport-https \\
          


        

Answer 1

The recommendation I received for this was to use the -v parameter in docker run to map the docker socket between containers like this:

-v /var/run/docker.sock:/var/run/docker.sock
