Install on Cobia (23.10)

investigating moving from Truecharts to docker-compose apps via a docker jail using this video as a starting point and 'install' is no longer an option. I can run jlmkr.py list and nothing is created but when I tried to create the docker jail from the jailmaker template it errors-out.

Using image from local cache
Unpacking the rootfs

You just created a Debian bookworm amd64 (20240901_05:24) container.

To enable SSH, run: apt install openssh-server
No default root or user password are set by LXC.
root@truenas:/mnt/tank/jailmaker# ./jlmkr.py start docker

Starting jail docker with the following command:

systemd-run --property=KillMode=mixed --property=Type=notify --property=RestartForceExitStatus=133 --property=SuccessExitStatus=133 --property=Delegate=yes --property=TasksMax=infinity --collect --setenv=SYSTEMD_NSPAWN_LOCK=0 --unit=jlmkr-docker --working-directory=/mnt/tank/jailmaker/jails/docker '--description=My nspawn jail docker [created with jailmaker]' --property=ExecStartPre=/mnt/tank/jailmaker/jails/docker/.ExecStartPre -- systemd-nspawn --keep-unit --quiet --boot --bind-ro=/sys/module --inaccessible=/sys/module/apparmor --machine=docker --directory=rootfs --notify-ready=yes --network-bridge=br1 --resolv-conf=bind-host '--system-call-filter=add_key keyctl bpf'

Job for jlmkr-docker.service failed.
See "systemctl status jlmkr-docker.service" and "journalctl -xeu jlmkr-docker.service" for details.

Failed to start jail docker...
In case of a config error, you may fix it with:
jlmkr.py edit docker

Before I start digging deeper, do I just need to download jlmkr.py into my jailmaker dataset and start creating jails per the jailamaker documentation or is there a step I am missing?

Thanks in advance for help with this noob!

Solved my issue .... default script assumes a bridge interface is in place and I did not have one. changed 'systemd_nspawn_user_args=--network-bridge=br1' to 'systemd_nspawn_user_args=--macvlan=eno1' and things are progressing in what appears to be a normal way.
