-====== Ubuntu - Docker - Assign a hostname to the container ======
-The value supplied to the **--hostname** command is set inside **/etc/hostname** and **/etc/hosts** inside the container.  Consequently, it appears in command prompt.  It plays a role in configuring container DNS and can be helpful while in the learning stages of a multi-container setup.  It is not easy to access from outside the container, but it will appear in the container's log files, and when those files are written to a volume independent of the host, it can make it easier to identify the container.

-While **<nowiki>--name</nowiki>** and **<nowiki>--hostname</nowiki>** are both useful for identification of containers, sometimes, it's not about naming the container at all.  Rather, it's about having a container clean up after itself without having to remember to do it yourself.
