 The container would be accessed using port 8080.
 
 To see the exposed ports of a container run `docker port <CONTAINER_NAME>`. In this example run `docker port webserver`.

+To change the hostname of a container use the `-h` or the `--hostname` argument when running a container.

+For example to create a container with the hostname of `abc` run the following
+
+```bash
+docker run -it -h abc ubuntu bash
+```
+This will create a Ubuntu container with the hostname `abc`. This container will be running bash and the terminal will have a similar output
+```bash
+$ root@abc:/#
+```
+
+Setting a hostname of a container will also alter the containers host file.

+To check this run the following `cat /etc/host`

+```bash
+127.0.0.1 localhost

+// Other entries

+172.17.0.2 abc abc
+```

+Please note, your container IP will be different.

+## Types of Docker volumes
+There are two type of volumes in Docker.  
+The first is a Docker bind mount which is a path from the host machines directory structure to a mount point inside the container.
+The second is a Docker named volume. This is a managed mount point in Docker which allows the attachment from multiple containers.

+## How to create a bind mount
+
+To create a bind mount use the `-v` argument when running a container. This argument has two parts seperated by a `:`. 
+
+```bash
+-v <HOST_DIR>:<CONTAINER_DIR>
+```
+The left hand-side of the `:`  is the directory structure from the host machine. 
+The right hand-side of the `:` is the mount point of the container.  
+
+To mount the host machines home directory into a new directory called data on the container run the following
+```bash
+$ docker run -it -v ~/home/peterfisher:/data ubuntu bash
+```
+
+## How to crate a Docker volume
+To create a Docker volume when running a container use the `-v` argument like the bind example but instead of supplying a path from the host machine pass a name of the volume that you wish to create,
+```bash
+-v <VOLUME_NAME>:<CONTAINER_DIR>
+```
+To create a Docker volume called `data` which is mounted to the container at the path `/data`  run the following
+
+```bash
+$ docker run --name test1 -it -v data:/data ubuntu bash
+```
+A named Docker volume can also be attached to another container at a different mount point.
+The following example attaches the same data Docker volume to a new container called `test2`. The Docker volume is mounted at the path `/data/store` in the container.
+```bash
+$ docker run --name test2 -it -v data:/data/store ubuntu bash
+```
+## To list Docker volumes
+To list all the docker volumes on the hostmachine run the following
+```bash
+$ docker volume list
+```
+
+## To create a Docker volume
+To create a Docker volume without create or running a Docker container run the following
+```bash
+$ docker volume create <VOLUME_NAME>
+```
+
+## How to attach volumes from another container
+To mount volumes that are attached from other containers pass the `--volumes-from` argument when creating a new container.
+The above command could be simplified by replacing the `-v` argument with the `--volumes-from` argument.  Please note that both the name of the Docker volume and the original mount point inside the container will be copied. 
+```bash
+$ docker run --name test2 -it --volumes-from test1 ubuntu bash
+```
+
+## How to inspect volume configuration
+To inspect the mounts of a container run the following command and look for the mounts section in the JSON output.
+```bash
+$ docker inspect <CONTAINER_NAME_OR_ID>
+```
+
+
+To inspect the configuration of a Docker volume run the following 
+```bash
+$ docker volume inspect <VOLUME_NAME>
+```
+This will show the name of the volume, the driver and the mount point of the container.
