# d2vm full example

This example demonstrate the setup of a ZSH workstation.

*Dockerfile*
```dockerfile
FROM ubuntu

# Install some system packages
RUN apt update && DEBIAN_FRONTEND=noninteractive apt install -y --no-install-recommends \
      qemu-guest-agent \
      netplan.io \
      ca-certificates \
      dnsutils \
      sudo \
      openssh-server

# Setup default network config
COPY 00-netconf.yaml /etc/netplan/
# Add a utility script to resize serial terminal
COPY resize /usr/local/bin/

# User setup variables
ARG USER=d2vm
ARG PASSWORD=d2vm
ARG SSH_KEY=https://github.com/${USER}.keys

# Setup user environment
RUN DEBIAN_FRONTEND=noninteractive apt install -y --no-install-recommends \
      bash-completion \
      curl \
      zsh \
      git \
      vim \
      tmux \
      htop

# Create user with sudo privileged and passwordless sudo
RUN useradd ${USER} -m -s /bin/zsh -G sudo && \
      echo "${USER}:${PASSWORD}" | chpasswd && \
      sed -i 's|ALL=(ALL:ALL) ALL|ALL=(ALL:ALL) NOPASSWD: ALL|g' /etc/sudoers

# Add ssh public keys
ADD ${SSH_KEY} /home/${USER}/.ssh/authorized_keys
# Setup permission on .ssh directory
RUN chown -R ${USER}:${USER} /home/${USER}/.ssh

# Run everything else as the created user
USER ${USER}

# Setup zsh environment
RUN bash -c "$(curl -fsSL https://gist.githubusercontent.com/Adphi/f3ce3cc4b2551c437eb667f3a5873a16/raw/be05553da87f6e9d8b0d290af5aa036d07de2e25/env.setup)"
# Setup tmux environment

# Setup auto login serial console
RUN sudo sed -i "s|ExecStart=.*|ExecStart=-/sbin/agetty --autologin ${USER} --keep-baud 115200,38400,9600 \%I \$TERM|" /usr/lib/systemd/system/serial-getty@.service
```

*00-netconf.yaml*
```yaml
network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      dhcp4: true
      nameservers:
        addresses:
        - 8.8.8.8
        - 8.8.4.4

```

**Build**

```bash
USER=mygithubuser
PASSWORD=mysecurepasswordthatIwillneverusebecauseIuseMostlySSHkeys
OUTPUT=workstation.qcow2

d2vm build -o $OUTPUT --force --build-arg USER=$USER --build-arg PASSWORD=$PASSWORD --build-arg SSH_KEY=https://github.com/$USER.keys .
```

Run it using *libvirt's virt-install*:

```bash
virt-install --name workstation --disk $OUTPUT --import --memory 4096 --vcpus 4 --nographics --cpu host --channel unix,target.type=virtio,target.name='org.qemu.guest_agent.0'
```
... you should be automatically logged in with a **oh-my-zsh** shell

From an other terminal you should be able to find the VM ip address using:
```bash
virsh domifaddr --domain workstation
```

And connect using ssh...
