Error: Missing environment variable MYGATEWAY.

[lukdz]

Maybe i'm making something wrong, but when following instruction i get error "Error: Missing environment variable MYGATEWAY." Despite exporting it. I can fix it by retyping export comand, but I would consider it a bug.

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  sudo usermod -aG docker pi

Remember that you will have to log out and back in for this to take effect!

WARNING: Adding a user to the "docker" group will grant the ability to run
         containers which can be used to obtain root privileges on the
         docker host.
         Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
         for more information.
