Jailmaker won't install Docker for you, but it can setup the jail with the capabilities required to run docker. You can manually install Docker inside the jail using the [official installation guide](https://docs.docker.com/engine/install/#server) or use [convenience script](https://get.docker.com).

## Nvidia GPU
To make passthrough of the nvidia GPU work, you need to schedule a Pre Init command. The reason is that TrueNAS SCALE by default doesn't load the nvidia kernel modules (and jailmaker doesn't do that either).
```
[ ! -f /dev/nvidia-uvm ] && modprobe nvidia-current-uvm && /usr/bin/nvidia-modprobe -c0 -u
```
