Will Fangtooth have a path to migrate jailmaker jail?

[mooglestiltzkin]

holy cow. thx for the ping stux.

hm… is incus good?

sorry i have zero info prior to this.

Docker in Incus is Awesome

Incus Docker Containers

Incus Containers Step by Step

i’m sure other newbies like me will be thinking, how to deploy containers using incus in the new incus system? using existing docker containers.

Anyway i imagine migrating would be similar to this somewhat

TrueNAS Scale: Migrating Sandboxes to Docker in Electric Eel // Compose, Dockge & Jailmaker

but that’s using docker containers, so not sure if incus uses the same? or not

How to run Docker inside Incus containers

Incus and Docker both use Linux kernel features to containerize your applications. Incus is best suited when you need system-level containers that act like traditional VMs and provide a persistent developer experience. On the other hand, Docker containers are ephemeral, i.e., temporary in nature. All files created inside Docker containers are lost when your Docker container is stopped or removed unless you stored them using volumes in different directories outside Docker. Docker is created as a disposable app deployment system. Incus containers are not typically created as disposables, and data is kept inside when they are stopped. Because of the Linux kernel support nesting feature, you can run Docker inside Incus. This page explains how to run Docker inside Incus containers.

Step 1- Creating an Incus container with a Docker and btrfs filesystem

I’ve tested this with only the BTRFS filesystem. ZFS is not supported for Docker and it is not recommended it is not recommended to use the zfs Docker storage driver for production use unless you have substantial experience with ZFS on Linux.) to use the zfs Docker storage driver for production use unless you have substantial experience with ZFS on Linux. So, it is best to stick with BTRFS as the backend driver.

Running Docker in Incus Containers

ByPieter Bakker 22/11/2024

This guide demonstrates how to properly set up and run Docker inside an Incus container on Debian 12. It builds upon our previous article “Installing Incus on Debian 12 with ZFS Storage” and focuses on the secure deployment of Docker in a containerized environment.

Prerequisites

• Incus installed and configured with ZFS storage (refer to our previous article)
• Debian 12 (Bookworm) host system
• Root or sudo access
• ZFS 2.2 or later (for proper overlay support)

ok this one by pieter sounds more promising.

Anyway i hope stux or someone releases a youtube explaining this whole thing and what to do.

to keep it simple, i’m sure most newbs like myself will know about docker deployment. so they want to know if they can do the same with the incus change or not… nevermind jailmaker as that seems to be a dead end at that point. but how to deploy docker if possible under incus?

in eel using the inbuilt docker support, you can pick the image from catalog and deploy that way. OR, use the advance, then add your own docker compose yaml, and deploy that way.

I’m the type of user who deploys using a docker compose yaml, so wondering how that would work in the incus change

In the Docker in Incus is Awesome youtube video @ 2:00 he examines how to use a docker compose yaml and see if it can be deployed in Incus somehow. I guess this is really i want to know

as long as i can get dockge up and running (with the new change), and deploy all my docker container yaml from dockge, i’d be happy if that was possible in fangtooth

@etorix

Sub-question: Will existing jailmaker/systemd sandboxes keep running after upgrade to Fangtooth?

this would be ideal for me also. if i can just leave my jailmaker as is, and it will continue to work in fangtooth

May also want to check out this thread in regards to incus

Linux Jails (containers/vms) with Incus (PoC)

INTRODUCTION For those who have or currently use Jailmaker, we know that the project is EOL and has no maintainer (Thank you for all your effort @Jip-Hop!). It provided an easy solution for creating jails using systemd-nspawn. This was useful for creating highly customizable environments that are not as heavy as full virtual machines. IX is moving in a different direction in TrueNAS SCALE 25.04 with inclusion of Incus. With that in mind, Jailmaker isn’t really needed in it’s current form. Th…

This thing Dan is working on seems like a possible solution. But have to see how Fangtooth works on release.

The important part mentioned for Dan’s project (jailmaker substitute using incus, in preparation for fangtooth)

Does this work?

Yes! Standard containers work, install docker, and can install and run docker images. Mounts can write data through to your host and datasets you are assigning to your containers which are configured under devices: and type: disk with shift: true enabled.

I guess will all these big changes, i’ll just sit out fangtooth, see what the situation is then decide what to do then
