-====== Ubuntu - Docker - Launch a Docker Container ======
-Launching a container is simple as **docker run** + the image name you would like to run + the command to run within the container.
-If the image doesn't exist on your local machine, Docker will attempt to fetch it from the public image registry.
-It’s important to note that containers are designed to stop once the command executed within them has exited.  For example, if you ran **/bin/echo hello world** as your command, the container will start, print hello world and then stop:
-<code bash>
-docker run ubuntu /bin/echo hello world
-</code>
-<WRAP info>
-**NOTE**:  Docker containers stop running as soon as the command they issued is complete, so this example will stop the container when the echo command has displayed "hello world".
-</WRAP>
-----
-An alternative method is:
-<code bash>
-docker run -ti ubuntu
-</code>
-  * **-t**:  Runs a terminal.
-  * **-i**:  Allow us to interact with it.
-This allows continuous use of the container until the terminal is exited by running the "exit" command.
