#### Building with predefined docker images
If you want to custom an ISO file to address your offline scenario, you can predefined images for system-docker and user-docker.
RancherOS supports `APPEND_SYSTEM_IMAGES`, it can save images to the initrd file, and loaded with system-docker when booting.
You can build ISO like this:
```
APPEND_SYSTEM_IMAGES="rancher/os-openvmtools:10.3.10-1" make release
```
RancherOS also supports APPEND_USER_IMAGES, it can save images to the initrd file, and loaded with user-docker when booting.
You can build ISO like this:
```
APPEND_USER_IMAGES="alpine:3.9 ubuntu:bionic" make release
```
Please note that these will be packaged into the initrd, and the predefined images will take up the resource footprint at startup.
