Failed to connect to bus: No such file or directory

I have created a docker 16.4 container and trying to run a docker within the container. Following this article.

https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-16-04

I followed everything but when I start the container I get the following issues.

root@1c2464056cff:/# sudo systemctl status docker
