TrueNAS SCALE can create persistent Linux ‘jails’ with systemd-nspawn. These containers are very similar to Jails from TrueNAS CORE or LXC, LXD and Incus containers on Linux. Jailmaker helps with the following: Setting up the jail so it won’t be lost when you update SCALE Choosing a distro (Debian…

Tried --bind=/dev/sda:/dev/sda, but still not works.

Solution (thanks to @Jip-Hop scrutiny docker container - /dev/sd* · Jip-Hop/jailmaker · Discussion #62 · GitHub ) docker_compatible=1 and --bind-ro=/dev/sda in systemd_nspawn_user_args was the solution.

I have problem with jailmaker on freshly installed 24.04 RC1 with root account disabled (recommended option during installation). Documentation on TrueNAS website and github page says Jailmaker installation and operation has to be done with root account, i had to append sudo with every command until…

Can’t you become root with sudo su?

To rule out it has anything to do with the jlmkr alias I recommend you to run ./jlmkr.py create directly from the jailmaker directory. In case you’re not already root, you’d probably have to put sudo in front.

Anyone might know offhand why bridge networking might not be working? I get these errors when I try: root@dockerrt:/etc/docker# docker container start 7a6d30e48198 Error response from daemon: failed to add interface vethaa2cec3 to sandbox: error setting interface "vethaa2cec3" IP to 172.31.0.2/16: …

I found docker - Failed to add interface to sandbox - Stack Overflow and docker compose - cannot program address in sandbox interface because it conflicts with existing route - Stack Overflow From the looks of it it doesn’t seem to be a jailmaker specific issue.

I have found several issues with the latest version of Docker, 26.0.2. Many containers stopped working with networking errors, after upgrading to it. I have managed to get them working by downgrading Docker to 26.0.1, with the following shell command: apt-get install docker-ce=5:26.0.1-1~debian.1…

Considering I just did the cross-grade from ubernerd/nerdctl to jailmkr only today, I might have been bitten in the ass by this then. The containers that were configured with host networking started fine, while the bridged ones didn’t. I’m gonna try downgrading Docker. –edit: Yay, it fixed it!
