jailmaker VS iocage

I run docker on scale using a Debian jail. It works great, and has basically no overhead or networking/device issues like a VM.

I decided not to go the Truecharts or even TrueNas charts way for running my apps and instead used this script to set up what's effectively a low-overhead VM to run Docker in: https://github.com/Jip-Hop/jailmaker

Personally, I just switched from Openmediavault to Truenas. Truenas handles storage much better. For docker apps I run a Debian jail, rather than a VM. Jails are more performant and easier to manage IMHO. This is what I used to create the jail: https://github.com/Jip-Hop/jailmaker

An alternative is this. I have migrated all my apps to a “jail” (basically a Debian vm that runs on top of the scale os). It gives you full control of your containers. You could use the same compose or docker run that you used on unraid to recreate the container.

I've been using the jail maker script https://github.com/Jip-Hop/jailmaker in bridge networking mode and it works great. Host networking (which is the default) is a bit annoying because you can use any of the normal ports 22/80/443 since they're all used by TrueNAS.

Either I'll spin up a VM and pass through a GPU or I'll try this out.

Check out https://github.com/Jip-Hop/jailmaker. I love it. Have all my containers and docker compose running through there. No need to recreate the wheel, mess around with gui apps and the like.

Also recommend you take a look at Jailmaker, which runs docker in a SystemD-based jail and will save you from a lot of potential grief in the future when Ix Systems changes something again.

100% OP. iX' path with SCALE and Truecharts is heartbreaking. Fencing themselves in to this ecosystem, deleting the Linux -open way of doing things with like docker or else. Hopefully they get the community vibe against k3s and will build something useful into truenas in the future. For now there is this LXC-like linux jails: https://github.com/Jip-Hop/jailmaker

Pains me immensely to say this, but that's the direction things have been moving in for a while now. The list of services I run on FreeBSD versus Linux hosts is steadily growing smaller. iocage hasn't had any changes in a year and a half and I'm not convinced iXsystems will still be developing CORE in the five-to-ten year timeframe.

I am was considering writing a PR for iocage but looking through the github (https://github.com/iocage/iocage) I see there have been no commits in a year and A PR for a decent features has sat waiting for review for over a year and a half. There are also open multiple PR's for bug fixes which are failing CI, with multiple contributors saying it's the CI tests that are broken, not their code.

Install https://github.com/iocage/iocage, it will make your life a lot easier

While trying to move jails between servers using iocage export and import, I found that iocage 1.2 (the currently packaged version) was reading the entire imported file into RAM. For a large jail, this is a clear problem. I found that there was a bug filed for it - and even a fix! - but a version containing the fix had not been released.

That looks like a solid guide. I use iocage to manage my jails. It takes care of a lot of details. Certainly more user-friendly for the first time getting jails set up.
