Creating a container

Creating a docker container is like creating a virtual machine, but simpler.

$ docker run --interactive --tty ubuntu:bionic

The docker container has a filesystem and a shell which behaves like any other linux environment.

root@8cb04a117f04:/# uname -smr 
Linux 5.0.0-redacted x86_64

root@8cb04a117f04:/# ls
bin  boot  dev  etc  home  lib  lib64  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var

root@8cb04a117f04:/# exit
