Docker run
The `docker run` command is one of the most used commands when we use the docker CLI (Command Line Interface).

Under the Hood, `docker run` are 2 commands:
docker create+docker start
- a container layer is created on the top of an image
- the container just created is started
It's important to understand this to avoid confusion between docker run, docker start, and docker create

Assign a name (--name)
By default, a random name is assigned, but in general is a good idea to assign a custom name to our containers, as we do to our pets!

Remove the container when exits (--rm)
Useful for disposable containers and examples. When a container is stopped, it’s automatically removed. Handy
