How apps work is, guaranteed, going to confuse the hell out of a lot of people come release. The standard line is "Kubernetes is what most(?) businesses use, Ix is focused on the enterprise, e.g. it was the right choice". Yet that isn't universally true, and even if it was they've implimented Kubernetes so that you are meant to use it their way - through the UI - with no guarantees that any command-line tools will work, or keep working. Even kubectl, the basic cli tool for Kubernetes, needs to be aliased i.e. it doesn't appear available at first to users. I found that out digging around the forum.
Anyone schooled in K8s is going to be confused by this approach, since it's not how you work with it in many other environments. And if you aren't schooled in it, even the simplified UX - and I appreciate the work that's gone in to abstracting this, I know it isn't easy - is confusing. I'm puzzled by who this is aimed at.
Business that use K8s for container orchestration, or plan to, will want to do so in a standardized, cross platform way. End users who want a nice ZFS based NAS that runs easy to deploy docker apps will find this to be massively over-complicated. And the official stance of "well, you can use the cli tools, but no guarentees it won't break anything" or "you can leverage docker-compose, but no guarentees it won't break anything (in fact, in order to use docker - outside of the docker container support they made part of the K8s deployment - you have to modify the daemon.json file to get iptables support and host networking, and that file gets over-written on updates) or "if you really want docker just run it in a VM" - something that people already do today with TrueNAS Core and find lacking - none of this is particularly comforting.
I also appreciate what the Truecharts folks are doing with their curated apps, but that also introduces problems. Official docker-compose support - or at least semi-official - would have been a lot simpler for those that don't use K8s and there are a million support resources for it.
