====== Docker - Containers - Assign a hostname to the container ======

<code bash>
docker run --hostname=value
</code>

or

<code bash>
docker run -h value
</code>


<WRAP info>
**NOTE:**  **<nowiki>--name</nowiki>** and **<nowiki>--hostname</nowiki>** are both useful for identification of containers.

The value supplied to the **--hostname** command is set inside **/etc/hostname** and **/etc/hosts** inside the container.

Consequently, it appears in the command prompt of the container.

It plays a role in configuring container DNS.

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.
