+===== Run a Container and Publish Container Ports =====
-If the image doesn't exist on your local machine, Docker will attempt to fetch it from the public image registry.
+<code bash>
+docker container run --name docker-nginx -d -p 8080:80 nginx
+</code>
+where:
+  * **8080** is the port of the Docker host.
+  * **80** is the port of the container where the application is running.
+<WRAP info>
+**NOTE:**  You can verify the port 8080 using the URL http://docker-host-ip:8080 in your web browser.
+An optional host-ip can also be set:
+<code bash>
+docker container run -p [host-ip]:[host-port]:[container-port]
+</code>

+===== Remove the Container After Exit =====
+<code bash>
+docker container run --rm mongo
+</code>
+----
+===== Run a Container and Mount Host Volumes =====
+By default, Docker containers do not save the data. When a container is stopped and the process is completed, all data generated by the container is removed.
+Sometimes you may need to run a container that requires persistent storage. In that case, you can use Docker volume to make the data persist and also share it across the multiple containers.
+<code bash>
+docker container run --name docker-nginx -d -p 8080:80 -v /mnt:/var/www nginx
+</code>
+<WRAP info>
+**NOTE:**  Any data written to **/var/www** within the container is actually accessing **/mnt** on the host.
+This option is useful for anyone running a database or application that requires persistence within Docker.

+===== Example =====
 For example, if you ran **/bin/echo hello world** as your command, the container will start, print hello world and then stop:
