|
|
|
|
```
|
|
|
|
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
|
|
```
|
|
|
