# ZSH Workstation example
This example demonstrate the setup of a ZSH workstation with *cloud-init* support.
*Dockerfile*

```
There is no need to configure the network as **d2vm** will generate a *netplan* configuration that use DHCP.
**Build**
```bash
USER=mygithubuser
PASSWORD=mysecurepasswordthatIwillneverusebecauseIuseMostlySSHkeys
OUTPUT=workstation.qcow2
d2vm build -o $OUTPUT --build-arg USER=$USER --build-arg PASSWORD=$PASSWORD --build-arg SSH_KEY=https://github.com/$USER.keys --force -v .
```
Run it:
```bash
d2vm run qemu --mem 4096 --cpus 4 $IMAGE
```
... you should be automatically logged in with a **oh-my-zsh** shell
You should be able to find the ip address inside the VM using:
```bash
hostname -I
# or
ip a show eth0 | grep inet | awk '{print $2}' | cut -d/ -f1
```
And connect using ssh...
In order to quit the terminal you need to shut down the VM with the `poweroff` command:
```bash
sudo poweroff
```
*I hope you will find it useful and that you will have fun...*
