Persistent Debian 'jail' on TrueNAS SCALE to install software (docker-compose, portainer, podman, etc.) with full access to all files via bind mounts. Without modifying the host OS at all thanks to systemd-nspawn!

Development of Jailmaker continues in this git repo.

I've opened up Github Discussions to further discuss Jailmaker.

can you define safe? If you add an external interface is any network traffic to/from the Docker going through that interface or is there still shared network resources of the host?

By safe I mean if IX decides to remove Docker from their base Scale host install (like they going to do I believe) and just keep k3s/containerd, my install of Docker (running under their system) shouldn't be affected. As it's really no different than any other custom container running. So unless they do away with all custom containers, leaving only installs from app catalogs, it should be fine. That would be extreme IMO, and even then I guess it could be done by creating a catalog and config, etc -- but would be a pain.

As far as networking goes, adding other interfaces just gives flexibility. Basically I wanted my Docker apps with their own interface (leaving NAS & Plex stuff alone on my main 10G interface). So I gave it one interface on the LAN one one that's a private network for internal service backends for other machines (dbs, message bus, etc) as I do dev work. Both show (net1, net2) in the docker container with local routes to their subnets. So local traffic from Docker apps to the LAN uses net1 for example. But by default the default internet route would be the eth0 interface that the custom container provides via k3s. But that can be changed by just changing the default route within the Docker container to point to my gateway off net1 for example.

Anyway, I have messages from you guys on Discord so we can continue there. : )

I think it makes more sense now to continue the discussion over here:
